1 Introduction
1.1 KMC is retained by LW Developments Ltd to provide transport advice in relation to the
proposed redevelopment of Northaw House in Northaw, Hertfordshire from office use to
provide 27 residential units. This Transport Statement has been prepared to support the
detailed planning application made to Welwyn Hatfield Borough Council.
1.2 The Transport Statement has been prepared in accordance with planning practice guidance
on ‘Travel Plans, Transport Assessment and Statements’ (March 2014) and the Roads in
Hertfordshire Highway Design Guide 3rd Edition.
1.3 A Transport Statement Scoping Note was submitted to Hertfordshire County Council (HCC)
in March 2018 and the Scoping Note along with the pre-application response received from
HCC are included in Appendix A.
Site History
1.4 Northaw House is a Grade II Listed building originally constructed in 1698. Set in circa 10
hectares, the property has been used as a private dwelling, boys preparatory school and
hospital until it was purchased in 1972 by a firm of architects and converted to office use. It
continued to be used by the architects until 2014. Whilst the main house is now vacant, some
of the other buildings on the site were until recently occupied by office tenants and there is
also a single residential flat. The majority of the buildings have a lawful B1 office use. Oak
Cottage has a lawful use as a single dwelling (use class C3).
1.5 The most relevant recent planning history is the planning permission granted by Welwyn
Hatfield Borough Council, on 1 October 2009 (ref S6/2004/0573/FP). The consent was for 13
residential units comprising the conversion of the main building to a single large house; the
stable block to a single 5 bedroom dwelling; the ballroom wing to 3 dwellings and 7 new
build dwellings; extensions and alterations to Oak Cottage to create a 3 bedroom house; car
parking and associated landscape works. It was proposed for all development traffic to be
accessed via the western access. This consent was for 5 years and expired on 1 October
2014.
1.6 At the time of the 2009 consent, HCC concluded that the proposals were acceptable in
transport terms given the net reduction in traffic generated by the scheme compared to the
extant office use. Based on this, HCC concluded that the proposal would not have an
unreasonable impact on the safety and operation of the adjoining highways subject to the
inclusion of conditions.

2 Existing Conditions
Site Location
2.1 The site is located on the western edge of the village of Northaw, approximately 2 miles east
of Potters Bar. The location of the site is illustrated in Figure 2.1 below.
Figure 2.1 – Site Location
2.2 The site is bound to the north and east by Judge’s Hill, to the west by Coopers Lane and to
the south by fields. The site plan with red line boundary is included as Appendix B.
Walk and Cycle Accessibility
2.3 Facilities within easy walking distance of the site include Northaw Church of England Primary
School, a pre-school, public houses and a sports field. A footway is provided on at least one
side of the roads connecting to these local facilities.
2.4 It is reasonable to expect that able-bodied people are capable of walking at least 2km for
day to day activities. The thrust of sustainable policy is that there will be an increasing
propensity for people to use non-single car occupancy modes of which walking is one. The
2km walking isochrone from the centre of the site is provided at Figure 2.2 below and shows
that all of Northaw village is within walking distance as well as some of Potters Bar.

December 2018
2.6 The footpaths to the west of the site connect to Great North Road and Hatfield Road in
Potters Bar. The footpath to the east of the site provides a connection to Cuffley.
2.7 With regards to cycling, the nearest National Cycle Route to the site is Route 12, which starts
at Haddley Wood and routes north connecting to towns in the vicinity of the A1, including
Hatfield, Welwyn Garden City and Stevenage.
2.8 Central Government research states that cycling has the potential to substitute for short car
trips, particularly those under 5km, and to form part of a longer journey by public transport.
Cycling is an attractive form of travel and it is reasonable to expect that for able-bodied
people a cycle distance of 5km is readily achievable and attractive. Figure 2.4 below shows
the 5km cycle isochrone from the existing western access.

Public Transport
Bus
2.9 An eastbound bus stop is located opposite the western access to Northaw House on
Coopers Lane and a westbound bus stop is located 100m to the south of the western site
access. This set of bus stops is served by Route 242, which provides a service between
Potters Bar and Waltham Cross via Cuffley and Cheshunt.
2.10 There are 1 to 2 services an hour in each direction in the morning and evening peak periods
and two services in each direction during the day. The timetable is included as Appendix C.
2.11 Route 242 provides access to Cuffley railway station to the east, which is 5 minutes by bus
from Northaw. It also provides access to Potters Bar railway station to the south-west of the
site, which is 10 minutes by bus from Northaw.
Rail
2.12 The site is a similar distance from Cuffley and Potters Bar railway stations. Cuffley railway
station is on the Great Northern Hertford Loop and services run to Finsbury Park, Moorgate,
Hertford and Letchworth Garden City. Potters Bar station provides services to London Kings
Cross, Moorgate and Welwyn Garden City. Table 2.1 below summarises the services from
these stations.

2.13 It can be seen from Table 2.1 that the site has good access to rail to a number of London
railway stations as well as towns within Hertfordshire.

Highway Network
2.14 Access to the existing site is from Coopers Lane to the west of Northaw House. Coopers
Lane has a speed limit of 40mph, which reduces to 30mph within Northaw village and on the
approach to Potters Bar.
2.15 An Automatic Traffic Count (ATC) was commissioned for 7 days commencing 11/1/18. The
ATC was located immediately to the south of the western access on Coopers Lane and the
raw survey data is included in Appendix D.
2.16 Table 2.2 below summarises the weekday vehicular flows recorded on Coopers Lane.
Table 2.2 – Baseline Traffic Flows on Coopers Lane
Direction AM Peak

PM Peak
Hour 1700-
1800
Eastbound / Northbound 252 360
Westbound / Southbound 293 179
Two-way 545 539
2.17 It can be seen that the two-way vehicular flows are similar in the AM and PM peak hours with
just over 500 two-way vehicles per hour, which equates to less than 10 two-way vehicles per
minute.
2.18 Table 2.3 below summarises the average and 85th percentile speeds recorded over the
survey period in each direction on Coopers Lane in the vicinity of the western access.

Percentile
Speed
Eastbound / Northbound 31 mph 35 mph
Westbound / Southbound 32 mph 36 mph
Two-way 32 mph 36 mph
2.19 The speed limit on this part of Coopers Lane is 40mph and the survey shows that the average
and 85th percentile speeds are below the speed limit (i.e. 32mph average speed and 36mph
85th percentile speed).

December 2018
2.20 With regards to the Strategic Road Network (SRN), the site is within close proximity to the
M25 and A1. The nearest access to the M25 is from Junction 24 to the south of Potters Bar.
Access to the A1 is from Junction 23 of M25.
Accident History
2.21 Accident data for the most recent 5 year period (i.e. since 1st January 2013) has been
obtained from the Crashmap database, which summarises the Personal Injury Collisions (PICs)
for the surrounding highway network. Figure 2.5 shows the location of the PICs and Table 2.4
below summarises the PICs.

2.22 It can be seen from Table 2.4 that there have been 13 PICs in the last 5 years in the vicinity of
the site. None of these involved vulnerable road users and all but one were slight incidents.
The 1 serious PIC involved a male crashing his car at 7am on a Sunday morning on Northaw
Road West and no other vehicles were involved.
2.23 There have been no PICs at the eastern access within the last 5 years. The nearest PIC to the
eastern site access was a slight PIC at the junction of Northaw Road West with Vineyards
Road, circa 120m to the east of the eastern site access.
2.24 There have been no PICs at the western access in the last 5 years but there have been 3
slight PICs at the junction of Coopers Lane with Wells Road, which is opposite the site
access. The PICs involved a vehicle colliding with a vehicle turning right. 2 of the PICs were in
2014 and one in 2016 and there have not been any other collisions at the junction since then.

December 2018
2.25 The speed survey demonstrates that the speeds are well within the speed limit in the vicinity
of the site access and there are warning signs in place eastbound warning vehicles of the
bend in Coopers Lane.
2.26 PIC data for a further 5 years (i.e. 2008 – 2012) has also been reviewed to determine if there
is an accident issue at either of the proposed site accesses. This showed that there was only 1
further PIC in the vicinity of the western site access during this period. It was a slight PIC in
December 2011 in the dark and involved a car proceeding around the bend and crashing
into a ditch. There were no PICs in the vicinity of the eastern access.
2.27 Therefore, over the last 10 year period there have been 3 slight PICs in the vicinity of the
western access and no PICs in the vicinity of the eastern access. This was during the period
that the western access was being utilised as offices at a far higher intensity than proposed as
part of this application. As such, it is considered that there is not an existing accident issue at
the site accesses.
2.28 Notwithstanding this, a number of improvements are proposed to the site accesses based on
a Stage 1 Road Safety Audit commissioned by KMC and audited by HCC, which are
summarised in Section 4.

3 Policy Context
3.1 This section summarises the relevant national and local policy in the context of the site and
the proposed development.
National Policy and Guidance
National Planning Policy Framework (NPPF)
3.2 The National Planning Policy Framework (July 2018) sets out the Government’s planning
policies for England and how these are expected to be applied.
3.3 Section 9 of the newly published NPPF sets out the national policy on promoting sustainable
transport.
3.4 Paragraph 108 states that it should be ensured that:
a) “appropriate opportunities to promote sustainable transport modes can be – or have
been – taken up, given the type of development and its location;
b) safe and suitable access to the site can be achieved for all users; and
c) any significant impacts from the development on the transport network (in terms of
capacity and congestion), or on highway safety, can be cost effectively mitigated to an
acceptable degree.”
3.5 Paragraph 109 goes on to state that:
“Development should only be prevented or refused on highways grounds if there would be
an unacceptable impact on highway safety, or the residual cumulative impacts on the road
network would be severe.”
3.6 The framework supports the provision of Travel Plans to manage demand and the provision
of sustainable facilities on site to reduce the need to travel where practical. Paragraph 111
states that:
“All developments that will generate significant amounts of movement should be required to
provide a travel plan, and the application should be supported by a transport statement or
transport assessment so that the likely impacts of the proposal can be assessed.”
Northaw House Transport Statement Page | 12
December 2018
National Planning Practice Guidance
3.7 Following the withdrawal in October 2014 of The Department for Transport (DfT) ‘Guidance
on Transport Assessment’ (March 2007) , the DfT published the Planning Practice Guidance
(NPPG) suite of guidance, which is continually being updated. This guidance is intended to
assist all stakeholders in determining whether an assessment may be required and, if so, what
level and scope that assessment should include.
3.8 The “Travel Plans, Transport Assessments and Statements” section of NPPG was last
updated in March 2014 and summarises what these documents are and how they relate to
each other. It goes on to summarise the key principles of a Travel Plan, Transport Assessment
and Transport Statement and what should be included in them.
3.9 With regards to scope and level of detail to be included in a Transport Assessment or
Statement the guidance states that this will vary from site to site but the following should be
considered when settling the scope of the proposed assessment:
• “information about the proposed development, site layout, (particularly proposed
transport access and layout across all modes of transport)
• information about neighbouring uses, amenity and character, existing functional
classification of the nearby road network;
• data about existing public transport provision, including provision/ frequency of services
and proposed public transport changes;
• a qualitative and quantitative description of the travel characteristics of the proposed
development, including movements across all modes of transport that would result from
the development and in the vicinity of the site;
• an assessment of trips from all directly relevant committed development in the area (ie
development that there is a reasonable degree of certainty will proceed within the next
3 years);
• data about current traffic flows on links and at junctions (including by different modes of
transport and the volume and type of vehicles) within the study area and identification of
critical links and junctions on the highways network;
• an analysis of the injury accident records on the public highway in the vicinity of the site
access for the most recent 3-year period, or 5-year period if the proposed site has been
identified as within a high accident area;
• an assessment of the likely associated environmental impacts of transport related to the
development, particularly in relation to proximity to environmentally sensitive areas
(such as air quality management areas or noise sensitive areas);
Northaw House Transport Statement Page | 13
December 2018
• measures to improve the accessibility of the location (such as provision/enhancement of
nearby footpath and cycle path linkages) where these are necessary to make the
development acceptable in planning terms;
• a description of parking facilities in the area and the parking strategy of the
development;
• ways of encouraging environmental sustainability by reducing the need to travel; and
• measures to mitigate the residual impacts of development (such as improvements to the
public transport network, introducing walking and cycling facilities, physical
improvements to existing roads.”
Manual for Streets
3.10 Manual for Streets (2007) provides guidance for new streets and modifications to existing
streets. It aims to increase the quality of life through good design which creates more
people-oriented streets. Although the detailed guidance in the document applies mainly to
residential streets, the overall design principles apply to all low speed streets.
3.11 Manual for Streets provides geometric guidelines for low trafficked residential streets,
examines the effect of the environment on road user behaviour, and draws on practice in
other countries. Research undertaken by Transport Research Laboratory (TRL) provides the
evidence base upon which the geometric guidelines in Manual for Streets are based,
including link widths, forward visibility, visibility splays and junction spacing. Also introduced
in Manual for Streets is the Quality Audit which replaces the Safety Audit as the assessment
tool for interventions. The Quality Audit ensures that more than just safety is considered
during assessment.
3.12 It is recommended that the design of a scheme should follow the user hierarchy shown in the
table below.
Table 3.2: Road User Hierarchy
Source: Department for Transport, MfS
Northaw House Transport Statement Page | 14
December 2018
3.13 The ‘Road User Hierarchy’ as shown above puts forward walking and cycling as the two
preferred modes of travel, followed by public transport. It is recommended that where
possible a scheme should follow this proposed hierarchy.
Local Policy
Welwyn Hatfield District Local Plan (2005)
3.14 Local policy is contained within the Welwyn Hatfield District Plan adopted in 2005, with
saved polices in place until they are replaced by the adoption of the emerging Local Plan.
3.15 Transport policy is set out in the Movement chapter. Policy M1 relates to integrating
movement and land use and states:
“Through the development process the Council will take every opportunity to integrate
different modes of travel. Development proposals, except for those which are necessary in
rural areas, will be permitted only in locations with accessibility to pedestrian and cycle
routes and passenger transport services, or where this can be created, and where the
environment and infrastructure can accommodate the amount and type of transport
movement likely to be generated. In considering development proposals, the Council will
give priority to walking and more sustainable modes of travel.
Internal layouts in development schemes must demonstrate priority to non-car users. They
must include safe and effective routes for pedestrians and cyclists, with appropriate facilities,
as well as catering for people with mobility difficulties and making provision for passenger
transport and where appropriate the needs of horse riders.”
3.16 Policy M5 relates to pedestrian facilities and states:
“…..The Council will require proposals for new development to give priority to pedestrian
access in their layouts through the inclusion of safe and direct routes linking to existing or
proposed footpath networks and facilities…….”
3.17 Policy M6 relates to cycling facilities and states:
“The Council will require proposals for new development to encourage cycling through the
inclusion of safe cycle routes and parking for cycles, and where appropriate secure
waterproof storage and changing and showering facilities for cyclists. New cycle routes
should link with existing or proposed cycle paths. Developers may be required to provide or
contribute towards off-site facilities and the overall planned cycle network……”
Northaw House Transport Statement Page | 15
December 2018
Welwyn Hatfield Emerging Core Strategy
3.18 In 2009, Welwyn Hatfield Borough Council consulted on issues and options for the Core
Strategy. In 2012, the Council consulted on the Emerging Core Strategy, which set out the
Council’s preferred strategy and objectives for guiding the future development of Welwyn
Hatfield up to 2029 in terms of housing, jobs and the infrastructure that needs to accompany
growth - including schools, shops and roads.
3.19 Policy CS1 on Delivering Sustainable Development and states, amongst other things “that
the location of new development should deliver a sustainable pattern of development which
protects areas of highest environmental value; minimises the need to travel by directing
growth to those areas with good transport networks and which are well served by jobs,
services and facilities.”
Welwyn Hatfield Emerging Local Plan
3.20 The Welwyn Hatfield Local Plan was submitted for examination in May 2017 and the
examination is currently ongoing.
3.21 Section 7 of the Emerging Local Plan deals with Movement and Policy SP4, with regards to
transport and travel states that:
“Consistent with the vision and objectives of this Local Plan, the Council will seek to support
both planned growth and existing development with appropriate transport infrastructure,
with the emphasis on promoting the use of sustainable modes of travel and on improving
safety for all highway users. The Council will work together with the County Council as the
local highway authority, Highways England, public transport operators, developers and other
relevant bodies to design and fund improvements to transport infrastructure where these are
necessary to support growth or to improve accessibility to existing centres, employment
areas and community facilities.”
3.22 Policy SADM2 is with regard to highway network and safety and states:
“Development proposals will be permitted provided:
i) There would be no unacceptable impacts on the local and /or strategic transport
network. Development proposals which generate a significant amount of traffic
movements must be accompanied by either a Transport Assessment or Transport
Statement as appropriate in accordance with the criteria in the Hertfordshire County
Council Highway Design Guidance;
Northaw House Transport Statement Page | 16
December 2018
ii) There would be no negative impacts on highway safety;
iii) They are designed to allow safe and suitable means of access and site operation; and
iv) They provide satisfactory and suitable levels of parking.”
Roads in Hertfordshire Highway Design Guide 3rd Edition
3.23 Hertfordshire County Council has produced a design guide, 'Roads in Hertfordshire -
Highway Design Guide 3rd Edition' that gives details of the design and construction
standards that must be met before roads are adopted.
3.24 Northaw House is currently accessed via a simple priority junction with Coopers Lane. It is
proposed that the internal road within the site is extended, which will connect to the mini-
roundabout on Judges Hill to the east. As a result, there would be two vehicular access
points to the proposed development, which would be connected by the internal road.
3.25 The internal access road is not being sought for adoption by HCC and will remain as a
private road maintained by the landowner. The internal access road is 4.8m wide.
Welwyn Hatfield Supplementary Planning Guidance Parking Standards
(January 2004)
3.26 In January 2004, the Council adopted new parking standards as Supplementary Planning
Guidance (SPG) to the District Plan Review. The SPG sets maximum standards for provision in
new development and enables these to be reduced in accessible locations.
3.27 The parking standards for residential use outside of Zones 1 and 2 are as follows:
• 1.25 spaces per bedsit or 1 bedroom unit;
• 1.5 spaces per 2 bedroom unit;
• 2.25 spaces per 3 bedroom unit; and
• 3 spaces per 4+ bedroom unit.
3.28 Disabled parking standards are for 1 space for every dwelling built to mobility standards.
3.29 Cycle parking standards are 1 long term space per unit if no garage or shed provided.
Northaw House Transport Statement Page | 17
December 2018
Welwyn Hatfield Interim Policy for Car Parking Standards and Garage Sizes
(August 2014)
3.30 Welwyn Hatfield Borough Council issued Interim Policy for Car Parking Standards and
Garage Sizes in August 2014. Within this Policy, the Council has e agreed to treat its existing
car parking standards as guidelines rather than maximums. This means that higher or lower
car parking standards than those set out in the SPG can be proposed (by landowners,
developers, etc) and determined (by officers and elected councillors) on a case-by-case basis
taking account of the relevant circumstances of the proposal, its size context and its wider
surroundings, as well as the NPPF guidance. The onus is on developers to demonstrate
through transport information submitted alongside their planning applications that a greater
or lesser level of car parking provision is appropriate.

4 Development Proposals
4.1 This section summarises the development proposals with a focus on the transport aspects of
the proposals.
Development Quantum
4.2 It is proposed to provide 27 residential dwellings on the site, which comprise the conversion
of Northaw House to provide 11 apartments and the development of 16 houses either
through the conversion of existing buildings or new-build. The proposed site layout is
included in Appendix E.
4.3 Table 4.1 below summarises the proposed development in terms of residential units.

• 4 x 1 bedroom flats;
• 6 x 2 bedroom flats;
• 1 x 4 bedroom flat;
• 6 x 3 bedroom houses; and
• 10 x 4 bedroom houses.
• 1.25 spaces per bedsit or 1 bedroom unit; 1.25
• 1.5 spaces per 2 bedroom unit; 6 * 1.5 = 9
• 2.25 spaces per 3 bedroom unit; and 6 x 2.25 = 13.5
• 3 spaces per 4+ bedroom unit. 11*3 = 33
Northaw House Transport Statement Page | 19
December 2018
Car Parking
4.5 It is proposed to provide a total of 57 car parking spaces for the residential units, in
accordance with the current Welwyn Hatfield parking guidelines. In addition, it is proposed
to provide 12 visitor car parking spaces for the residential units, which is an average of 0.4
visitor parking spaces per unit. It is therefore proposed to provide a total of 69 car parking
spaces for the development. 16 of the car parking spaces will be provided in a basement car
park to be accessed to the front of Northaw House.
4.6 By way of comparison, it is understood that the extant office use previously provided over
100 car parking spaces on the site, all of which were at grade. There will therefore be a net
reduction in car parking.
Access Strategy
4.7 The vehicle access for the extant office use of the site was solely via the western access with
all traffic entering and exiting the site to/from Coopers Lane. However, the east and west
accesses from Judges Hill and Coopers Lane, respectively, have always been operational,
albeit over recent years the eastern access has only been used by the Eastern Lodge, which
lies just outside of the redline boundary.
4.8 Originally the internal access road to Northaw House connected the east and west accesses.
However, over time a section of the internal access road was taken out of use. It is proposed
to reinstate this section of internal access road as shown in Figure 4.1 below.
Figure 4.1 - Section of Internal Access Road to be Reinstated
Northaw House Transport Statement Page | 20
December 2018
4.9 The land required to extend the internal estate road and connect with the eastern access is
within land owned by the developer and will enable residential traffic to access and egress
the site from both the east and the west. This will act to disperse traffic onto the highway
network and provide pedestrian access to the local facilities within Northaw village.
4.10 It is envisaged that the eastern site access will only be used for travelling to and from the east
and that the western access will be used for travelling to and from the north and west, due to
these routes being the most direct. The proposed access strategy is shown in Figure 4.2
below.
Figure 4.2 – Proposed Access Strategy
4.11 The western access is currently a priority junction with Coopers Lane and the eastern access
is currently a mini-roundabout with Judges Hill and Northaw Road West.
4.12 Coopers Lane in the vicinity of the western access has a 40mph speed limit and the ATC
survey showed that the 85th percentile speed northbound is 35mph and southbound is
36mph. Judges Hill and Northaw Road West in the vicinity of the eastern access both have a
30mph speed limit.
4.13 The visibility splays at the western and eastern accesses are shown on Drawings KMC-01 and
KMC-02 respectively and are included in Appendix F.
Northaw House Transport Statement Page | 21
December 2018
4.14 Drawing KMC-01 shows the visibility splays in each direction of 2.4m x 59m, which is for a
vehicle speed of 37mph in accordance with Table 7.1 of Manual for Streets. This is the splay
that should be provided for the observed 85th percentile speeds of 35 and 36mph.
4.15 Drawing KMC-01 shows that this splay is achievable to the right but that a splay of 2.4m x
45m not 59m is achievable to the left. This is commensurate with vehicle speeds of 31mph,
which is in accordance with the observed average speed of 32mph but slightly below the
observed 85th percentile speed of 35mph.
4.16 Drawing KMC-02 shows the visibility splays in each direction of 2.4 x 43m, which is for a
vehicle speed of 30mph in accordance with Table 7.1 of Manual for Streets. Drawing KMC-02
shows that this visibility splay is achievable in both directions.
4.17 Based on the pre-application advice from HCC, a Stage 1 Road Safety Audit (RSA) was
commissioned by KMC to audit the existing site accesses to the development. The RSA is
included in Appendix G of this report.
4.18 Five problems were identified by the RSA, four at the western access and one at the eastern
access. The Designer’s Response to the RSA is included in Appendix H of this report.
4.19 The Stage 1 RSA and the Designer’s Response were submitted to HCC for review by the
Road Safety Officer. The HCC review is included as Appendix I.
4.20 To address the issues identified in the RSA and the subsequent HCC review, it is proposed to
make a number of improvements to the site accesses. The proposed improvements are
illustrated in Drawing KMC001-001 Rev 2 included in Appendix J and meet all of the
requirements set out by HCC in the Safety Review. HCC concluded that, the proposed
highway works would result in a low risk of reduction in service level and, as such, are
considered appropriate to proceed to the next stage in the design process.
4.21 In summary it is proposed to implement the following improvements at the site accesses:
4.22 Western Access at Coopers Lane:
• Width of the site access to be reduced to reduce the width of the crossing route for
pedestrians and encourage reduced vehicular speeds to and from the highway;
• Existing centre line road markings on Coopers Lane in the vicinity of the western access
to be reinstated in accordance with Traffic Signs Regulations and General Directions
(TSRGD) Diagram 1004 and any broken road studs replaced as necessary;
Northaw House Transport Statement Page | 22
December 2018
• ‘Slow’ markings in accordance with TSRGD Diagram 1024 to be installed in each
direction on the approach to the bend on Coopers Lane in the vicinity of the western
access; and
• Overgrown vegetation to be cut back and hard standing area provided at the
northbound bus stop on Coopers Lane opposite the western access to improve the
boarding and alighting facilities.
4.23 Eastern Access at Judges Hill:
• Existing mini-roundabout road markings and associated signs to be removed and
replaced with priority junction road markings, with the eastern site access the minor arm
to the junction and Judges Hill and Northaw Road West the major arms. The changes
will include:
• remove of the existing mini-roundabout and give-way markings for the roundabout
and centre line markings to TSRGD Diagram 1004 extended along Judges Hill and
Northaw Road West in the vicinity of the eastern access;
• extend the length of full height kerb on the Northaw Road West approach to the
junction to improve the carriageway edge definition and reduce the length of
pedestrian crossing route across the access;
• replace the existing roundabout warning sign (for eastbound traffic) with a road
hump warning sign on a yellow backing board with appropriate distance plate;
• repeat the road hump warning sign and distance plate on the opposite side of
Judges Hill facing eastbound traffic;
• remove the existing mini-roundabout and give way signs on the westbound
approach to the mini-roundabout; and
• provide give-way road markings and sign on eastern access arm of the proposed
priority junction.
Refuse and Delivery Strategy
4.24 Welwyn Hatfield Borough Council collect household waste and recycling on alternate weeks.
It is therefore expected that there would be one refuse collection for the proposed
development each week, and currently this is scheduled to take place on Fridays.
4.25 Each house has been designed with refuse storage as shown on the Proposed Site Layout
included in Appendix E of this report. In addition, refuse storage has been designed at the
front of Northaw House.
Northaw House Transport Statement Page | 23
December 2018
4.26 Swept path analysis has been undertaken for a 12.1m long refuse vehicle, which are the
maximum length of refuse vehicles currently used in Hertfordshire. The swept path analysis is
included in Appendix J and shows the refuse vehicle entering the site via the western access,
travelling through the site within 10m of each refuse bin store and egressing the site via the
eastern access. It also shows the refuse vehicle entering from the eastern access,
manoeuvring through the site to each of the refuse bins and exiting via the western access.
The internal access road is 4.8m in width throughout the site.

5 Traffic Generation
5.1 This section summarises the traffic generation of the extant use, the proposed residential use
and the forecast net change in trips. The trip rates were agreed with HCC as part of the pre-
application scoping exercise.
Extant Trip Generation
5.2 The existing lawful land uses on the site are as follows:
• B1 offices use: 19,448 sqft / 1,789 sqm (GIA); and
• C3 residential use: 1 bedroom residential unit.
5.3 Office TRICS trip rates were provided by HCC as part of the pre-application scoping exercise
to be used to derive the extant office vehicular trips. The TRICS output for the extant office
use is included in Appendix K.
5.4 The TRICS trip rate database has been interrogated to derive vehicle trip rates for the extant
residential use and the TRICS output is included in Appendix K. These trip rates have been
agreed with HCC as part of the pre-application scoping exercise. The following search
criteria were used to derive the agreed private flats trip rates:
• South East, West Midlands, Yorkshire & North Lincolnshire, North West and North
• Suburban and Edge of Town
• Less than 100 private flats
5.5 Tables 5.1 and 5.2 below summarise the trip rates and associated trip generation for the
extant use.

5.6 Tables 5.1 and 5.2 demonstrate that the extant use of the site could generate in the region
of 52 two-way vehicle trips in the AM peak hour and 44 two-way vehicle trips in the PM peak
hour.
Proposed Residential Use
5.7 It is proposed to provide a mixture of houses and flats on the site. The TRICS trip rate
database has been interrogated to derive appropriate vehicle trip rates for private houses
(N.B. the same agreed trip rates for private flats has been applied as for the extant use). The
TRICS output is included as Appendix K. These trip rates have been agreed with HCC as part
of the pre-application scoping exercise. The following search criteria were used to derive the
trip rates:
• England, excluding Greater London
• Suburban and Edge of Town
• Less than 100 private houses
• Car Ownership 1.1 – 1.5 per household within 5 miles
5.8 Tables 5.3 and 5.4 below summarise the trip rates and associated trip generation for the
proposed 16 residential houses and 11 residential flats.

Net Vehicle Trip Generation
5.10 Based on the trip generation assessment, it has been demonstrated that there would be a
net reduction in vehicular traffic as a result of the proposed development. This is summarised
in Table 5.5 below.

6 Effects of the Development
Traffic Effects
6.1 As part of the pre-application consultation with HCC it was agreed that the proposed
development would generate considerably less vehicular trips in both the AM and PM peak
hours than the extant use. There will therefore be no impact on the highway network. In
addition, the proposed development is to utilise both the eastern and western site accesses,
which will further disperse traffic onto the highway network.
6.2 As part of the pre-application consultation with HCC it was agreed that, given the net
reduction in vehicular trips, an assessment of committed development and trip distribution is
not necessary. It was also agreed that junction modelling is not required.
Highway Safety Effects
6.3 A review of the PIC data has been undertaken in Section 2 of this report. The analysis
demonstrated that, over the last 10 year period, there have been 3 slight PICs in the vicinity
of the western access and no PICs in the vicinity of the eastern access. This was during the
period that the western access was being utilised as offices at a far higher intensity than
proposed as part of this application. As such, it is considered that there is not an existing
accident issue at the site accesses.
6.4 A Stage 1 RSA has been undertaken and HCC has also undertaken a Safety Review. A
number of improvements to the site accesses are proposed, which are summarised in Section
4 and illustrated in Drawing KMC001-001 Rev 2 included in Appendix J. HCC concluded that
the proposed highway works would result in a low risk of reduction in service level and, as
such, the proposed improvements are considered appropriate to proceed to the next stage
in the design process.
Construction Effects
6.5 Prior to commencement of the development, a Construction Traffic Management Plan
(CTMP) will be prepared and agreed with HCC. As part of the CTMP there will be a
commitment to provide adequate parking on site for construction vehicles to prevent on-
street conflict and impacts to highway safety.

7 Conclusions
7.1 KMC is retained by LW Developments Ltd to provide transport advice in relation to the
proposed redevelopment of Northaw House in Northaw, Hertfordshire from office use to
provide 27 residential units. This Transport Statement has been prepared to support the
detailed planning application made to Welwyn Hatfield Borough Council.
7.2 The conclusions can be summarised as follows:
• The site is within walk and cycle distance of local facilities at Northaw and Potters Bar;
• The site is also accessible to nearby train stations via the local bus service that routes
passed the site;
• A review of the PIC data shows that there is not an existing accident issue at the site
accesses;
• It has been demonstrated and agreed that the proposed development will have a net
reduction in vehicular trips compared to the extant use and there will therefore be no
impact on the surrounding highway network;
• Notwithstanding this, improvements are proposed to the east and west site accesses to
improve highway safety and provide enhanced bus stop facilities; and
• A CTMP will be prepared and agreed with HCC prior to commencement of the
development.
7.3 In summary, there are no transportation reasons why the proposals should not receive
planning consent.

Introduction
1. KMC is retained by LW Developments Ltd to provide transport advice in relation to the
proposed redevelopment of Northaw House in Northaw from office uses to provide 31
residential units. This technical note has been prepared to scope the Transport Statement
with Hertfordshire County Council (HCC). A Transport Statement will support the detailed
planning application to be made to Welwyn Hatfield District Council.
Site History
2. Northaw House is a Grade II Listed building originally constructed in 1698. Set in circa 10
hectares, the property has been used as a private dwelling, boys preparatory school and
hospital until it was purchased in 1970 by a firm of architects and converted to office use. It
continued to be used by the architects until 2014. Whilst the main house is now vacant,
some of the other buildings on the site are occupied by office tenants and there is also a
single occupied flat. In summary, the majority of the buildings have a lawful B1 office use.
The exception is Oak Cottage which has a lawful use as a single dwelling (use class C3).
3. The most relevant recent planning history was the planning permission granted by Welwyn &
Hatfield District Council, on 1 October 2009 (ref S6/2004/0573/FP). The consent was for 13
residential units comprising the conversion of the main building to a single large house; the
stable block to a single 5 bedroom dwelling; the ballroom wing to 3 dwellings and 7 new
build dwellings; extensions and alterations to Oak Cottage to create a 3 bedroom house; car
parking and associated landscape works. It was proposed for all development traffic to be
accessed via the western access. These consents were for 5 years and expired on 1 October
2014.
4. At the time of the 2009 consent, HCC concluded that the proposals were acceptable given
the net reduction in traffic generated by the scheme compared to the extant office use. HCC
considered the proposal would not have an unreasonable impact on the safety and
operation of the adjoining highways subject to the inclusion of conditions.

Existing Conditions
5. The location of the site is shown in Figure 1. The existing site plan is included in Appendix A.
6. The site is located on the western edge of the village of Northaw, approximately 2 miles east
of Potters Bar. Facilities within easy walking distance include Northaw Church of England
Primary School, a pre-school, public houses and a sports field. A footway is provided on at
least one side of roads connecting to these local facilities.
7. Access to the existing site is from Coopers Lane to the west of Northaw House. Coopers Lane
has a speed limit of 40mph, which reduces to 30mph within Northaw village and on the
approach to Potters Bar. The site is within close proximity to both M25, A1(M) and the A10.
8. A pair of bus stops are located at the western site access to Northaw House, which is served
by bus route 242 providing access to Cuffley railway station (5 minute journey time) and
beyond to Cheshunt and Waltham Cross to the east. Bus route 242 also provides access to
Potters Bar railway station to the south-west (10 minute journey time).
9. Cuffley railway station is on the Great Northern Hertford Loop and services run to Finsbury
Park, Moorgate, Hertford and Letchworth Garden City. Potters Bar station provides services
to London Kings Cross, Moorgate and Welwyn Garden City.
Development Proposals
10. It is proposed to provide 31 residential dwellings on the site, which comprise the conversion
of Northaw House to provide 11 apartments and the development of 20 houses either
through the conversion of existing buildings or new-build. The proposed site layout is
included in Appendix A.
11. Table 1 below summarises the proposed development in terms of residential units.
Table 1: Summary of Proposed Development
Building Type Residential Units
Northaw House Conversion 4 x 1 bedroom flats
6 x 2 bedroom flats
1 x 3 bedroom flat

Gate Lodges New Build 2 x 3 bedroom houses
Orchard Cottage New Build 1 x 4 bedroom house
Settlement Area New Build 6 x 3 bedroom houses
East Drive New Build 4 x 4 bedroom houses
Total 31 units
Page | 3
12. In summary, there are proposed to be:
• 4 x 1 bedroom flats;
• 6 x 2 bedroom flats;
• 1 x 3 bedroom flat;
• 11 x 3 bedroom houses; and
• 9 x 4 bedroom houses.
13. It is proposed to provide a total of 68 car parking spaces for the residential units, in
accordance with the current Welwyn Hatfield parking guidelines. In addition, it is proposed
to provide 16 visitor car parking spaces for the residential units, which is an average of 0.5
visitor parking spaces per unit. It is therefore proposed to provide a total of 84 car parking
spaces for the development. 22 of the car parking spaces will be provided in a basement car
park to be accessed to the front of Northaw House.
14. By way of comparison, it is understood that the extant office use previously provided over
100 car parking spaces on the site, all of which were at grade. This is consistent with the trip
generation forecast for the extant use set out below. There will therefore be a net reduction
in car parking.
Vehicle Trip Generation
Extant Use
15. The existing lawful land uses on the site are as follows:
• B1 offices use: 19,253 sqft / 1,789 sqm (GIA)
• C3 residential use: 1 bedroom residential unit
16. The TRICS trip rate database has been interrogated to derive vehicle trip rates for the extant
use and the TRICS output is included as Appendix B. The following search criteria were used
to derive the trip rates:
• England, excluding Greater London
• Suburban and Edge of Town
• GFA 1,000 – 3,000 sqm for the office use
• Less than 100 private flats
• Car Ownership 1.1 to 1.5 per household within 5 miles
17. Tables 2 and 3 below summarise the trip rates and associated trip generation for the extant
use.

18. Tables 2 and 3 demonstrate that the extant use of the site could generate in the region of 54
two-way vehicle trips in the AM peak hour and 67 two-way vehicle trips in the PM peak hour.
Proposed Residential Use
19. It is proposed to provide a mixture of houses and flats on the site. The TRICS trip rate
database has been interrogated to derive appropriate vehicle trip rates for private houses
(N.B. the same trip rates for private flats has been applied as for the extant use). The TRICS
output is included as Appendix B. The following search criteria were used to derive the trip
rates:
• England, excluding Greater London
• Suburban and Edge of Town
• Less than 100 private houses
• Car Ownership 1.1 – 1.5 per household within 5 miles
20. Tables 4 and 5 below summarise the trip rates and associated trip generation for the
proposed 20 residential houses and 11 residential flats.

21. Tables 4 and 5 demonstrate that the proposed use of the site would generate in the region
of 14 two-way vehicle trips in the AM peak hour and 15 two-way vehicle trips in the PM peak
hour.
Net Vehicle Trip Generation
22. Based on the trip generation assessment, it has been demonstrated that there would be a
net reduction in vehicular traffic as a result of the proposed development. This is
summarised in Table 6 below.
Table 6: Net Vehicle Trip Generation

Extant Trips 50 4 54 7 60 67
Proposed Trips 4 11 14 9 4 15
Net Change -46 +7 -40 +2 -56 -52
23. Table 6 shows that the proposed residential use of the site would generate considerably less
traffic in the AM and PM peak hours when compared against the extant use.
Access Strategy
24. The vehicle access for the extant use of the site was solely via the western access with all
traffic entering and exiting the site to/from Coopers Lane. Therefore, based on the trip
generation exercise set out earlier, 55-68 two-way vehicles would have used the western site
access in the AM and PM peak hours to access the former office use.
25. As part of the redevelopment of Northaw House, it is proposed to extend the historic
internal estate road to connect with the existing eastern access, which is currently only used
by the East Lodge beyond the site boundary.
26. The land required to extend the internal estate road and connect with the eastern access is
within land owned by the developer and will enable residential traffic to access and egress
the site from both the east and the west. This will act to disperse traffic onto the highway
network and provide pedestrian access to the local facilities within Northaw village.
27. Based on the forecast trip generation for the proposed residential units and assuming an
even distribution of traffic between the accesses, there would only be circa 7-8 two-way
vehicles using each of the accesses in the AM and PM peak hours.
28. The western access is a priority junction with Coopers Lane and the eastern access is a mini-
roundabout with Judges Hill. It is proposed that both accesses are retained as existing. The
layout of the existing site accesses with associated visibility splays is included within
Appendix C.

Transport Statement Scope
29. The application will be supported by a Transport Statement, which will summarise the
following:
• A review of relevant local and national planning policy;
• A summary of the existing transport accessibility by all modes of transport;
• A summary of the development proposals providing details on the parking, servicing
and access arrangements;
• Details of the extant and proposed trip generation and the net change in trips in the
AM and PM peak hours; and
• A summary of the transport effects of the proposed development.
30. Based on HCC Guidance for Business and Residential Development (May 2014), a Travel Plan
Statement is not required as the proposed development is less than 50 residential units.
Summary
31. This note sets out the proposed scope and strategy to be set out in the Transport Statement
to support the Northaw House detailed planning application.
32. It has demonstrated that the proposed redevelopment of Northaw House will generate
considerably less traffic in the AM and PM network peak hours than the extant use.
33. In addition, the note has summarised the proposed access strategy via the east and west
accesses, which will disperse traffic onto the highway network and improve walk/cycle
access to the local facilities in Northaw village.

Application type Pre application
Proposal Provision of 31 residential dwellings on the site, which comprise the conversion of Northaw House to provide 11 apartments and the development of 20 houses either through the conversion of existing buildings or new-build.
Decision Other
Description of the Proposal The proposal is for the redevelopment of Northaw House in Northaw to provide 31 residential dwellings. The proposed dwelling mix is as follows: - 4 x one bedroom dwellings; - 6 x two bedroom dwellings; - 12 x three bedroom dwellings; and, - 9 x four bedroom dwellings. It is proposed that a combination of both apartments and houses are provided within the dwelling mix. Northaw House is currently accessed via a simple priority junction with Coopers Lane. It is proposed that the internal road within the site is extended, which will connect to the mini-roundabout on Judges Hill to the east. As a result, there would be two vehicular access points to the proposed development, which would be connected by the internal road. No improvements are proposed to either junction.
Site Description Northaw House is currently used as B1 office land use, with 1 residential dwelling on site. The site is bound to the north, east, south and west by green open space. Judges Hill runs in an east - west direction further to the north of the site. Coopers Lane is situated to the west of the site and runs in a north - south direction. Coopers Lane and Judges Hill are classified as B, secondary distributor roads and are both subject to a 40mph speed limit. Analysis The applicant has provided a Transport Statement Scoping Note for consideration by Hertfordshire County Council (HCC). The purpose of the Transport Statement (TS) is to ensure that minimal impacts to safety and functionality of the highway network occur as a result of the new development. The applicant will need to ensure the TS is prepared in accordance with the Roads in Hertfordshire Highway Design Guide 3rd Edition. A Design and Access Statement (DAS) is required for all planning applications that have an impact on the highway, as outlined in Roads in Hertfordshire: Design Guide (3rd Edition). The DAS needs to include three potential aspects of access: - Why the access points for the development have been chosen; - How the site responds to road layout, road safety, and public transport provision; and - How everyone can move through the place on equal terms regardless of age, disability, ethnicity or social grouping. Policy Review The Transport Statement Scoping Note does not include a review of any policy documents. The applicant is required to consider the following policy documents within their Transport Statement: - National Planning Policy Framework (2012) - National Planning Practice Guidance - Manual for Streets - Welwyn Hatfield District Plan (2005) - Welwyn Hatfield Emerging Core Strategy - Welwyn Hatfield Emerging Local Plan - Roads in Hertfordshire Highway Design Guide 3rd Edition. Transport Assessment Trip Generation A trip generation profile for the existing site and proposed development has been provided as part of the Transport Statement Scoping Note. Existing Situation The TRICS database has been used to determine the vehicular trip generation for the existing office land use and residential dwelling. The following criteria was used in the site selection process: - Vehicle trip rates were considered; - Weekday surveys were chosen; - Category -02 - Employment - A - Office- was used for the office land use; - Category -03 - Residential - C - Flats Privately Owned- was used for the residential dwelling; - Suburban and edge of town sites were chosen; - Sites in England, excluding Greater London, were considered; - Sites with a GFA between 1000-3000sqm were chosen for the office land use; and, - Sites with less than 100 private flats were chosen for the residential land use.
The AM Peak has been identified as 08:00 - 09:00 and the PM Peak has been identified as 17:00 - 18:00. The vehicular trip rates presented in the TS for the office land use are as follows: - AM Peak: 2.880 arrivals, 0.208 departures and 3.008 two-way trips - PM Peak: 0.416 arrivals, 3.327 departures and 3.743 two-way trips The resultant trip generation for the 1789 GIA office is as follows: - AM Peak: 52 arrivals, 4 departures and 54 two-way trips - PM Peak: 7 arrivals, 60 departures and 67 two-way trips However, a review of the TRICS online database has resulted in a lower trip rate for the office use, in particular for the PM Peak. Therefore, the above trip rates are not considered acceptable. The trip rates obtained from HCC’s interrogation were as follows: - AM Peak: 2.604 arrivals, 0.292 departures and 2.896 two-way trips - PM Peak: 0.203 arrivals, 2.245 departures and 2.448 two-way trips The resultant trip generation for the 1798sqm GIA at the existing site is as follows: - AM Peak: 47 arrivals, 5 departures and 52 two-way trips - PM Peak: 4 arrivals, 40 departures and 44 two-way trips The vehicular trip rates presented in the TS for the residential dwelling are as follows: - AM Peak: 0.068 arrivals, 0.233 departures and 0.301 two-way trips - PM Peak: 0.226 arrivals, 0.102 departures and 0.328 two-way trips The resultant trip generation for the one dwelling at the existing site is as follows: - AM Peak: 0 arrivals, 0 departures and 0 two-way trips - PM Peak: 0 arrivals, 0 departures and 0 two-way trips This is considered acceptable. Proposed Development The TRICS database has been used to determine the trip generation for the proposed residential development. Different trip rates have been used for the proposed houses and the proposed flats at the development. This is considered acceptable. The following criteria was used in the site selection process for the houses: - Vehicle trip rates were considered; - Weekday surveys were chosen; - Suburban area and edge of town sites were considered; - Category -03 - Residential - A - Houses Privately Owned- was selected; - Sites in England, excluding Greater London were considered; and, - Sites with less than 100 dwellings were chosen. The vehicular trip rates presented in the TS for the houses are as follows: - AM Peak: 0.137 arrivals, 0.421 departures and 0.558 two-way trips - PM Peak: 0.366 arrivals, 0.164 departures and 0.530 two-way trips
The resultant trip generation for the 20 houses is as follows: - AM Peak: 3 arrivals, 8 departures and 11 two-way trips - PM Peak: 7 arrivals, 3 departures and 11 two-way trips The following criteria was used in the site selection process for the flats: - Vehicle trip rates were considered; - Weekday surveys were chosen; - Suburban area and edge of town sites were considered; - Category -03 - Residential - C - Flats Privately Owned- was selected; - Sites in England, excluding Greater London were considered; and, - Sites with less than 100 dwellings were chosen. The vehicular trip rates presented in the TS for the flats are as follows: - AM Peak: 0.068 arrivals, 0.233 departures and 0.301 two-way trips - PM Peak: 0.226 arrivals, 0.102 departures and 0.328 two-way trips The resultant trip generation for the 11 proposed flats is as follows: - AM Peak: 1 arrival, 3 departures and 3 two-way trips - PM Peak: 2 arrivals, 1 departure and 4 two-way trips The total trip generation profile for the 20 houses and 11 flats is as follows: - AM Peak: 4 arrivals, 11 departures and 15 two-way trips - PM Peak: 9 arrivals, 4 departures and 15 two-way trips This is considered acceptable. The Transport Statement Scoping Note does not include a multi-modal trip generation profile for the proposed development. Given the scale of the proposed development, this is considered acceptable. Net Impact The net impact of the vehicle trip generation following the closure of the offices and the development of the 31 residential dwellings, as presented in the Transport Statement Scoping Note, is as follows: - AM Peak: -46 arrivals, +7 departures and -40 two-way trips - PM Peak: +2 arrivals, -56 departures and -52 two-way trips However, with the amended trip generation, the net impact would be as follows: - AM Peak: -43 arrivals, +6 departures and -37 two-way trips - PM Peak: +5 arrivals, -56 departures and -36 two-way trips Committed Development The Transport Statement Scoping Note does not include consideration of any committed developments. Given the scale of the proposed development, this is considered acceptable. Trip Distribution The Transport Statement Scoping Note does not include a trip distribution profile for the proposed development. Due to the reduction in two-way vehicle trips during both peak periods, this is considered acceptable. It is not expected that the proposed development will have a detrimental impact on the surrounding network.
Impact on the Highway Network Junction Assessment The Transport Statement Scoping Note does not include any information on junction modelling. Due to the decrease in the number of two-way trips generated during both peak periods, this is considered acceptable and junction modelling is not required. Highway Safety The Transport Statement Scoping Note does not include a review of any collision data for the highway network surrounding the site. In any future submissions, the applicant is recommended to obtain and provide a review of collision data for the latest five year period from Hertfordshire County Council. Refuse and Service Delivery It is assumed that servicing and deliveries will take place within the curtilage of the site. The applicant will need to provide details on the number of service vehicles that will access the site, the size of the vehicles and the likely times of use. Highway Layout Vehicle and Pedestrian Access The Transport Statement Scoping Note states that the existing vehicular access to the site via the simple priority junction with Coopers Lane will be retained. In addition, the internal road within the site will be extended to connect to the Judges Hill roundabout to the east of the site. All new or altered site accesses will be required to be designed in accordance with Roads in Hertfordshire: Highway Design Guide 3rd Edition and will be subject to S278 agreements. The internal layout will need to be provided and the design will need to provide appropriate parking provisions in line with the Welwyn Hatfield parking standards and must provide appropriate arrangements to allow the largest vehicles accessing the development site to enter and exit the proposed access in forward gear. Therefore, the internal layout must provide sufficient space to ensure all vehicles using the proposed site are able to safely manoeuvre through, turn around and re-enter the highway in a forward gear. The proposed site access arrangements must be supported by a Stage 1 Road Safety Audit. If the roads of the internal layout are to be adopted by HCC, the roads must also be designed in accordance with Roads in Hertfordshire: Highway Design Guide 3rd Edition. Swept Path Analysis The applicant will need to provide swept path assessments of the proposed development for the internal layout and for the access proposals to ensure that servicing and refuse vehicles, and the largest delivery vehicles, can access and safely manoeuvre through the proposed development site. Road Safety Audit A Stage 1 Road Safety Audit will be required, at a minimum, to illustrate that proposed access arrangements are safe and appropriate. The Safety Audit should consider the road network through the site as well due to the interactions with pedestrians. Road Safety Audits will be required for all new or improved junctions as well. Parking Provision Car Parking Provision The Welwyn Hatfield Parking Standards set out the following maximum parking standards for new residential developments: - 1.25 spaces per one bedroom dwelling; - 1.5 spaces per two bedroom dwelling; - 2.25 spaces per three bedroom dwelling; and, - 3 spaces per four bedroom dwelling.
Based on the proposed dwelling mix, this equates to a maximum provision of 68 car parking spaces. The Transport Statement Scoping Note states that 68 car parking spaces will be provided for the residential units. An additional 16 visitor spaces will be provided. This equates to a total of 84 car parking spaces at the proposed development. Justification for the over-provision of the car parking at the proposed development should be provided in any future submissions. However, it will be the responsibility of the LPA to determine the acceptability of the vehicle parking provision. Cycle Parking Provision The anticipated cycle parking requirements for the proposed development are to be provided based on the standards set out in Welwyn Hatfield District Plan Supplementary Planning Guidance Parking Standards (January 2004). Accessibility Public Transport The closest bus stops to the proposed development are located on Coopers Lane, to the west of the site. Both bus stops comprise of a flag pole. The bus serving the stop can be used to reach Potters Bar and Waltham Cross. The site is serviced by Potters Bar Railway Station within a 2.1 mile distance from the proposed development location. The station is accessible by public transport and is reasonable cycling distance. Great Northern provide services from Potters Bar Station to many local areas including Finsbury Park and Hatfield. A summary of the accessibility of the site will be required as part of any future Transport Statement submission. Walking and Cycling A footway is provided on the east side of the Coopers Lane carriageway. Street lighting is not provided along Coopers Lane. A footway is provided on the south side of Judges Hill. There are no dedicated cycle facilities in the vicinity of the site. Travel Plan Due to the scale of the proposed development, a Travel Plan will not be required. Construction A Construction Traffic Management Plan (CTMP) will be required to ensure construction vehicles will not have a detrimental impact on the vicinity of the site and a condition will be required to provide adequate parking for construction vehicles on-site to prevent on-street conflict and impacts to the highway safety. Planning Obligations/Community Infrastructure Levy (CIL) Planning obligations will be determined at the planning application stage. Summary Hertfordshire County Council as Highway Authority have no objection to the proposed development in principle, subject to additional information to support that the proposed development would not have a detrimental impact on the local highway network.
The contents of this letter are an informal officer opinion and should not be taken as a formal response to a planning application. It may not reflect the contents of any formal reply made by the Highway Authority in response to an official consultation from the LPA on a planning application for a similar proposal.

1 INTRODUCTION
1.1 This report presents the findings from a Stage 1 Road Safety Audit (RSA) undertaken on the proposed site access arrangements to a residential development to the north-west of Northaw, Hertfordshire.
1.2 The audit was carried out by the following:
Tristan Brooks BSc (Hons), MBA, CMILT, MCIHT, MSoRSA, HE RSA Cert of Competency
- Road Safety Audit Team Leader
R Lister BSc (Hons), MSc, MRTPI, CMILT, MCIHT, MSoRSA
- Road Safety Audit Team Member
1.3 The RSA was commissioned by KMC Transport Planning who issued the Audit Brief and approved the Audit Team on behalf of LW Developments (the developer of the scheme). The overseeing organisation is Hertfordshire County Council.
1.4 The site visits were undertaken on Thursday 3rd May 2018 between 13:45-14:25 and on Tuesday 22nd May between 18:45-19:15 and comprised a walk and drive through of the area in the vicinity of the access arrangements. During the site visits both the weather and road surface were dry. Traffic in the vicinity of the scheme was considered to be relatively light.
1.5 Coopers Lane in the vicinity of the proposed western site access is subject to a 40mph speed limit and has no street lighting. It is noted that there is a double headed lighting column to the north of the western site access at the Coopers Lane/ Judges Hill/ Well road priority controlled ‘T’ junction. It was noted during the site visits that the carriageway markings were illegible and a number of the centreline road studs appeared to be damaged with the reflective lenses missing/damaged.
1.6 Judges Hill/ Northaw Road (w) in the vicinity of the proposed eastern site access is subject to a 30mph speed limit and is street lit. It was noted during the site visits that the carriageway markings on the approach to and at the mini roundabout were illegible.

1.7 The drawings and documents supplied for audit are listed at Appendix A. An annotated drawing showing the locations of the problems identified is provided at Appendix B.
1.8 The terms of reference of the audit are as that described in DMRB HD19/15 Guidelines on Road Safety Audits. This standard has been used for guidance only. The team has examined and reported only on the road safety implications of the scheme as presented and has not examined or verified the compliance of the designs to any other criteria.
1.9 The scope of the RSA is limited to the proposed access arrangements to the site that in summary will retain the existing site access arrangements to the site. The western site access will be provided via the 3 arm priority controlled ‘T’ junction with Coopers Lane. The eastern site access will be provided via the 3 arm Judges Hill/Site Access/ Northaw Road (w) mini roundabout.
1.10 Information included as part of the audit brief has indicated the following:
• The proposed development will see the existing office use and 1 apartment within the site redeveloped to accommodate 31 residential units comprising 11 apartments and 20 houses;
• The proposed use of the site is forecast to generate less traffic movements than the sites extant use i.e. office;
• The eastern access to the site via the Judges Hill/Site Access/ Northaw Road (w) mini roundabout currently only serves 1 residential property; and
• The development proposals will permit access to/from the development via both the eastern and western access points;
• It is anticipated that the peak hour two-way traffic movements to/from each of the proposed site access points will be in the order of 7-8 vehicle movements during the AM and PM peak periods; and

• Vehicle speed data recorded on Coopers Lane in the vicinity of the western site access has indicated that the 7 day average and 85th percentile vehicle speeds in either direction were 37mph and 32mph respectively.
1.11 A review of the Personal Injury Collisions (PIC) data between 01/01/2013 and 31/06/2017 in the vicinity of the proposed site accesses has indicated that there have been 3 PICs recorded in the vicinity of the western site access of which all resulted in injuries that were slight in severity.
1.12 A review of PIC descriptions has indicated the following:
• 2 of the PICS occurred in 2014 and 1 in 2016;
• All occurred during the hours of daylight;
• All occurred at the Coopers Lane/Well Road junction; and
• All involved vehicles in the act of turning right, which would indicate failure to give way type collisions.
1.13 The Audit Team have not been made aware of any previous RSA’s undertaken on the scheme, or have they been made aware of any departures or relaxations from standard within the design of the scheme.
1.14 The recommendations included within this report should not be regarded as being prescriptive design solutions to the problems raised. They are intended only to indicate a proportionate and viable means of eliminating or mitigating the identified problem, in accordance with HD19/15. There may be alternative methods of addressing a problem which would be equally acceptable in achieving the desired elimination or mitigation and these should be considered when responding to this report.

2 ROAD SAFETY AUDIT FINDINGS FROM RSA 1
WESTERN SITE ACCESS VIA COOPERS LANE
PROBLEM 1
LOCATION: Site access.
SUMMARY: Excessive junction radii may result in the level of visibility to the right for drivers egressing the site being reduced due to the angle drivers would approach the junction.
2.1 It is likely that due to the what is considered to be an excessive junction radii (at the south west corner of the junction) that vehicles egressing the site will be positioned at an undesirable angle (deflection angle) which will necessitate them to turn their head significantly to the right in order to see vehicles approaching the junction from the north-east Coopers Lane, which could potentially result in an increased risk of injudicious exit manoeuvres into the path of oncoming vehicles.
2.2 This issue would also be more prevalent for elderly drivers who often have less mobility and have difficulty in turning their head, reducing the level of visibility achievable.
RECOMMENDATIONS
2.3 It is recommended that the junction radii are reduced at the south west corner of the junction to encourage drivers to approach the junction at a 90 degree angle.
2.4 It is recommended that any change to the junction radii should be accompanied by vehicle swept path analysis to ensure that the proposed layout does not result in vehicle encroachment into opposing lanes when using the junction.
PROBLEM 2
LOCATION: Site access.
SUMMARY: Conspicuity of the junction and potentially excessive vehicle speeds may result in an increased risk of shunt or failure to give type collisions.
Proposed Site Access Arrangements, Northaw House, Hertfordshire – Stage 1 RSA 6 /go-surveys/Road Safety Audits/GS602 - Northaw, Stage 1 RSA/GS602-2018 - Proposed Site Access Arrangements Northaw House - Stage 1 RSA - Final.docx May 2018
2.5 It was noted during the site visits that:
• what appeared to be ‘slow’ carriageway markings and centreline road markings were illegible on the approach to the junction from the south; and
• a number of the centreline road studs appeared to be damaged with the reflective lenses missing/damaged.
2.6 It is considered that the omission of road markings, centre line road studs or the legibility of both could result in insufficient warning to drivers approaching the junction of the carriageway layout ahead, potentially resulting in excessive vehicle speeds on the approach to the junction which could result increased risk of shunt or failure to give type collisions.
2.7 It is noted that this is an existing issue, although the proposed use of the site may exacerbate this matter, due to the volume of traffic movements using the site access during a typical day.
RECOMMENDATION
2.8 It is recommended that ‘slow’ and centreline carriageway markings and road studs be reinstated in the vicinity of the site access.
PROBLEM 3
LOCATION: Site access.
SUMMARY: Inter-visibility to/from the site access obscured by a large tree within the visibility splay could increase the risk of side swipe type collisions.
2.9 The inter-visibility to/from the site access is in part restricted by the presence of a large tree within the verge to the north east of the site access (Ref: Photograph 1 and 2). Restricted inter-visibility to/from the site access could increase the risk of injudicious turning manoeuvres potentially resulting in an increased risk of side swipe type collisions.

Photograph 1 and 2: Tree within the visibility splay.
RECOMMENDATION
2.10 It is recommended that, if possible, the tree be removed from within the visibility splay.
PROBLEM 4
LOCATION: Bus stop opposite the site access.
SUMMARY: No footway/waiting facilities at the bus stop may result in pedestrian/ vehicle collisions.
2.11 The bus stop opposite the site (that serves northbound services) has no footway area for users wait on whilst boarding/alighting a bus (Ref: Photograph 2), nor does it have any dropped kerbs etc should a user with mobility impairments or user with a pushchair etc want to use this facility.
2.12 A lack of suitable boarding/alighting facilities at the bus stop could result in an increased risk of pedestrian/ vehicle collisions due to pedestrians crossing to use the bus stop at inappropriate locations or potentially waiting within the carriageway if using the bus stop.

Photograph 2: Bus stop opposite the western site access.
RECOMMENDATIONS
2.13 It is recommended that boarding/alighting facilities at the bus stop are improved to remove the problems identified.
EASTERN SITE ACCESS VIA MINI ROUNDABOUT
PROBLEM 5
LOCATION: Eastern site access -Northaw Road (w).
SUMMARY: Increase in vehicle movements at the site access arm of the mini roundabout may result in an increased risk of failure to give-way type collisions.
2.14 It is proposed that that the existing site access i.e. mini roundabout will be retained as part of the development proposals. It is considered that the retention of this junction type to

serve the access, would, due to the relatively low vehicle movements that will use the site access arm of the junction compared to the vehicle flows on the Northaw Road (w) and Judges Hill approaches to the junction, result in the imbalance in vehicle movements on the site access arm of the junction compared with the other arms of the roundabout. This is likely to result in a lack of compliance to the priority at the roundabout potentially resulting in an increased risk of failure to give-way type collisions.
RECOMMENDATION
2.15 It is recommended that the type of junction proposed is changed to remove this problem.

Subject Stage 1 Road Safety Audit – Designer’s Response
Ref 18001/N03
Date 24 May 2018
Page | 1 Company Number: 07988377
Registered Address: 82b High Street, Sawston, Cambridge, CB22 3HJ
Introduction
1. KMC is retained by LW Developments Ltd to provide transport advice in relation to the
proposed redevelopment of Northaw House in Northaw from office uses to provide 31
residential units.
2. Based on the pre-application advice from Hertfordshire County Council (HCC), a Stage 1 Road
Safety Audit (RSA) was commissioned by KMC for the site accesses to the development.
3. The scope of the RSA was limited to the proposed accesses to the site, which retain the
existing access arrangements. The western site access will be provided via the three-arm
priority controlled ‘T’ junction with Coopers Lane. The eastern site access will be provided via
the three-arm Judges Hill/Site Access/Northaw Road mini roundabout.
4. This note provides the designer’s response to the Stage 1 RSA.
Western Access via Coopers Lane
Problem 1 – Coopers Lane Site Access
Problem Summary
5. Excessive junction radii may result in the level of visibility to the right for drivers egressing
the site being reduced due to the angle drivers would approach the junction.
Recommendation
6. It is recommended that the junction radii are reduced at the south west corner of the
junction to encourage drivers to approach the junction at a 90 degree angle.
7. It is recommended that any change to the junction radii should be accompanied by vehicle
swept path analysis to ensure that the proposed layout does not result in vehicle
encroachment into opposing lanes when using the junction.
Page | 2
Designers Response
8. The Personal Injury Collision (PIC) data for the last 10 years has been analysed and
demonstrates that there has not been a PIC at the western site access during this period.
9. This was during the period that the western access was being utilised as offices at a far
higher intensity than proposed as part of this application. As such, the evidence
demonstrates that the junction radii does not present a highway safety issue and it is
considered that physical alterations are not necessary.
Problem 2 – Coopers Lane Site Access
Problem Summary
10. Conspicuousness of the junction and potentially excessive vehicle speeds may result in an
increased risk of shunt or failure to give type collisions.
11. It was noted during the site visits that:
• what appeared to be ‘slow’ carriageway markings and centreline road markings were
illegible on the approach to the junction from the south; and
• a number of the centreline road studs appeared to be damaged with the reflective
lenses missing/damaged.
Recommendation
12. It is recommended that ‘slow’ and centreline carriageway markings and road studs be
reinstated in the vicinity of the western site access.
Designers Response
13. The proposed development will generate considerably less than the extant use.
Notwithstanding this, it is recognised that the road markings in the vicinity of the western
site access have been eroded away and the road studs are damaged.
14. It is therefore proposed to provide ‘slow’ road markings and reinstate the centreline
carriageway markings and road studs in the vicinity of the site access.
Problem 3 – Coopers Lane Site Access
Problem Summary
15. Inter-visibility to/from the site access obscured by a large tree within the visibility splay could
increase the risk of side swipe type collisions.
Recommendation
16. It is recommended that, if possible, the tree be removed from within the visibility splay.
Page | 3
Designers Response
17. The tree is within the highway boundary and not on land within the ownership of the
developer. It is therefore outside of the control of the developer to remove the tree from the
visibility splay but is within the control of HCC.
18. Notwithstanding this, there have been no PICs at the western site access within the last 10
years during the period that the western access was being utilised as offices at a far higher
intensity than proposed as part of this application. As such, the evidence demonstrates that
the presence of the tree within the visibility splay does not present a highway safety issue
and it is considered that it is not necessary to remove the tree.
Problem 4 – Coopers Lane Northbound Bus Stop
Problem Summary
19. No footway/waiting facilities at the bus stop may result in pedestrian/vehicle collisions. A
lack of suitable boarding/alighting facilities at the bus stop could result in an increased risk of
pedestrian/ vehicle collisions due to pedestrians crossing to use the bus stop at
inappropriate locations or potentially waiting within the carriageway if using the bus stop.
Recommendation
20. It is recommended that boarding/alighting facilities at the bus stop are improved to remove
the problems identified.
Designers Response
21. The PIC data analysis over the last 10 years demonstrates that there has not been a PIC
involving a vulnerable road user anywhere in the vicinity of the site. There have not been any
PICs as a result of the lack of waiting facilities at the northbound bus stop. As such, it is
considered that the lack of waiting facilities at the bus stop does not pose a highway safety
issue.
22. Notwithstanding this, it is proposed to provide improved boarding and alighting facilities at
the northbound bus stop to enhance the accessibility of the development. Further details are
provided in the Transport Statement.
Eastern Access via Northaw Road
Problem 5 – Northaw Road Site Access
Problem Summary
23. Increase in vehicle movements at the site access arm of the mini roundabout may result in
an increased risk of failure to give-way type collisions.
Page | 4
24. It is proposed that that the existing site access i.e. mini roundabout will be retained as part
of the development proposals. It is considered that the retention of this junction type to
serve the access, would, due to the relatively low vehicle movements that will use the site
access arm of the junction compared to the vehicle flows on the Northaw Road (w) and
Judges Hill approaches to the junction, result in the imbalance in vehicle movements on the
site access arm of the junction compared with the other arms of the roundabout. This is
likely to result in a lack of compliance to the priority at the roundabout potentially resulting
in an increased risk of failure to give-way type collisions.
Recommendation
25. It is recommended that the type of junction proposed is changed to remove this problem.
Designers Response
26. It is likely that the eastern site access will only be used for travelling to and from the east and
that the western access will be used for travelling to and from the north and west as shown
in Figure 1 below.
Figure 1 – Proposed Access Strategy
27. It is considered unlikely that residents will use the eastern access to travel to/from the north
on Well Road or west on Coopers Lane as it would be quicker and simpler to use the western
access for these movements.
28. As such, the current alignment of the eastern access is designed to cater for the proposed
vehicle movements generated by the development. It is only the junction type that is raised
as a safety issue in the RSA due to the relatively low vehicle movements generated by the
Page | 5
development and the resultant imbalance of flows between the three mini-roundabout arms
and potential failure to give-way type collisions.
29. It is therefore proposed to remove the mini-roundabout and associated signage and change
the carriageway markings to a priority junction arrangement with the site access the minor
arm of the junction.

Development Management - Road Safety Review
Scheme Northaw House, Northaw. – Access Arrangements
App Ref: Road Safety Audit Ref – Go Surveys Ltd - RSA Stage 1 (Ref GS602-2018)
Review prepared by: Graham Beviss
Date: 25th July 2018
The following observations and comments are recorded in relation to the following “Problems” identified in the Stage 1 Road Safety Audit for the proposed highway works associated with the above site. The Reference Nos quoted in the later sections of this RSR document refer to the items identified in the Road Safety Audit prepared by Go Surveys Ltd dated 25th May 2018 and the Designers Response incorporated within that report. Any other concerns that are considered relevant are reported at the end of this document.
Safety Assessment ( to be completed by HCC Officer)
Consideration: In consideration of the comments recorded in the following sections of this review and assuming the additional HCC comments and recommendations are incorporated within the proposed works, the risk of a reduction in the level of road safety associated with the development proposal is assessed as:-
HCC (delete as appropriate):-
Safety Positive?
Safety Neutral?
Low Risk of reduction in service level.
*Medium Risk of reduction in service level?
**High Risk of reduction in service level?
** Assessments judged at “High Risk Reduction” will be followed up with a letter advising that the proposals will be the subject of a formal Road Safety Audit process at the current design stage. The primary concerns identified can be notified to the Applicant in the letter. * Assessments judged as “Medium Risk Reduction” will be discussed via a Safety Review meeting to confirm the Assessment and agree if the proposal should be the subject of a formal Road Safety Audit at the current design stage. - Assessments judged as “Low Risk Reduction”, “Safety Neutral” or “Safety Positive” are considered appropriate to proceed to the next stage in the design process.
2
RSA Problem Ref 1 – Coopers Lane Site Access.
Consideration: Possible risk of conflicts associated with wide access geometry.
Road safety audit concern and recommendation:
“Excessive junction radii may result in the level of visibility to the right for drivers egressing the site being reduced due to the angle drivers would approach the junction.”
Stage 1 RSA Recommendation – “It is recommended that the junction radii are reduced at the south west corner of the junction to encourage drivers to approach the junction at a 90 degree angle.
It is recommended that any change to the junction radii should be accompanied by vehicle swept path analysis to ensure that the proposed layout does not result in vehicle encroachment into opposing lanes when using the junction.”
Designers response:-
“The personal Injury collision (PIC) data for the last 10 years has been analysed and demonstrates that there has not been a PIC at the western site access during this period.
This was during the period that the western access was being utilised as offices at a far higher intensity than proposed as part of this application. As such, the evidence demonstrates that the junction radii does not present a highway safety issue and it is considered that physical alterations are not necessary.”
HCC Road Safety Review comment:-
The details identified in the designer’s response are not considered to be acceptable. The existing junction layout does not comply with current highway design standards. The width of the crossing route for pedestrians is too long to deliver a safe facility. The junction geometry also encourages high vehicle speeds to and from the highway. The Highway Authority will require that these issues are addressed as part of any proposed development of the site.
3
RSA Problem Ref 2 – Coopers Lane Site Access.
Consideration: Possible risk of conflicts associated with poor driver awareness of the road layout.
Road safety audit concern and recommendation:
“Conspicuousness of the junction and potentially excessive vehicle speeds may result in an increased risk of shunt or failure to give type collisions.
It was noted during the site visits that:
What appeared to be ‘slow’ carriageway markings and centreline road markings were illegible on the approach to the junction from the south; and
A number of the centreline road studs appeared to be damaged with the reflective lenses missing / damaged.”
Stage 1 RSA Recommendation – “It is recommended that ‘slow’ and centreline carriageway markings and road studs be reinstated in the vicinity of the western site access.”
Designers response:-
“The proposed development will generate considerably less than the extant use. Notwithstanding this, it is recognised that the road markings in the vicinity of the western site access have been eroded away and the road studs are damaged.
It is therefore proposed to provide ‘slow’ road markings and reinstate the centreline carriageway markings and road studs in the vicinity of the site access.”
HCC Road Safety Review comment:-
The details identified in the designer’s response are considered to be acceptable.
4
RSA Problem Ref 3 – Coopers Lane Site Access.
Consideration: Possible risk of conflicts associated with inadequate driver visibility.
Road safety audit concern and recommendation:
“Inter-visibility to/from the site access obscured by a large tree within the visibility splay could increase the risk of side swipe type collisions.”
Stage 1 RSA Recommendation – “It is recommended that, if possible, the tree be removed from within the visibility splay.”
Designers response:-
“The tree is within the highway boundary and not on land within the ownership of the developer. It is therefore outside of the control of the developer to remove the tree from the visibility splay but is within the control of HCC.
Notwithstanding this, there have been no PICs at the western site access within the last 10 years during the period that the western access was being utilised as offices at a far higher intensity than proposed as part of this application. As such, the evidence demonstrates that the presence of the tree within the visibility splay does not present a highway safety issue and it is considered that it is not necessary to remove the tree.”
HCC Road Safety Review comment:-
The details identified in the designer’s response are considered to be acceptable in principle. The alterations to the junction geometry identified and requested under Problem Ref 1 will improve the positioning of vehicles at the ‘Give Way’ position and improve driver visibility to and from it.
5
RSA Problem Ref 4 – Coopers Lane Northbound Bus Stop
Consideration: Possible risk of conflicts associated with inadequate bus stop facilities.
Road safety audit concern and recommendation:
“No footway/waiting facilities at the bus stop may result in pedestrian/vehicle collisions. A lack of suitable boarding/alighting facilities at the bus stop could result in an increased risk of pedestrian /vehicle collisions due to pedestrians crossing to use the bus stop at inappropriate locations or potentially waiting within the carriageway if using the bus stop.”
Stage 1 RSA Recommendation – “It is recommended that boarding/alighting facilities at the bus stop are improved to remove the problems identified.”
Designers response:-
“The PIC data analysis over the last 10 years demonstrates that there has not been a PIC involving a vulnerable road user anywhere in the vicinity of the site. There have not been any PICs as a result of the lack of waiting facilities at the northbound bus stop. As such, it is considered that the lack of waiting facilities at the bus stop does not pose a highway safety issue.
Notwithstanding this, it is proposed to provide improved boarding and alighting facilities at the northbound bus stop to enhance the accessibility of the development. Further details are provided in the Transport Statement.”
HCC Road Safety Review comment:-
The details identified in the designer’s response are not agreed in full. The proposed development will generate changes in the travel patterns to and from the site and the references to the previous road safety history in the vicinity of the site is not entirely relevant.
The proposed improvements to boarding and alighting facilities at the bus stop are considered relevant to the travel patterns associated with the development and are therefore supported.
6
RSA Problem Ref 5 – Eastern site access junction on Northaw Road.
Consideration: Possible risk of conflicts associated with failure to Give Way on the mini roundabout junction.
Road safety audit concern and recommendation:
“Increase in vehicle movements at the site access arm of the mini roundabout may result in an increased risk of failure to give-way type collisions.
It is proposed that the existing site access i.e. mini roundabout will be retained as part of the development proposals. It is considered that the retention of this junction type to serve the access, would, due to the relatively low vehicle movements that will use the site access arm of the junction compared to the vehicle flows on the Northaw Road (W) and Judges Hill approaches to the junction, result in the imbalance in vehicle movements on the site access arm of the junction compared with the other arms of the roundabout. This is likely to result in a lack of compliance to the priority at the roundabout potentially resulting in an increased risk of failure to give-way type collisions.”
Stage 1 RSA Recommendation – “It is recommended that the type of junction proposed is changed to remove this problem.”
Designers response:-
“It is likely that the eastern site access will only be used for travelling to and from the east and that the western access will be used for travelling to and from the north and west ……….
It is considered unlikely that residents will use the eastern access to travel to/from the north on Well Road or west on Coopers Lane as it would be quicker and simpler to use the western access for these movements.
As such, the current alignment of the eastern access is designed to cater for the proposed vehicle movements generated by the development. It is only the junction type that is raised as a safety issue in the RSA due to the relatively low vehicle movements generated by the development and the resultant imbalance of flows between the three mini-roundabout arms and potential failure to give-way type collisions.
It is therefore proposed to remove the mini-roundabout and associated signage and change the carriageway markings to a priority junction arrangement with the site access the minor arm of the junction.”
7
HCC Road Safety Review comment:-
The details identified in the designer’s response are not agreed in full. The existing mini roundabout serves as a speed reducing feature for southbound traffic on Judges Hill on the approach to the speed cushions on Northaw Road West. The conversion of the junction to a priority arrangement is acceptable but the proposals presented on Drawing No. KMC001-001 will need to be supported with the following additional measures:
Replace the existing roundabout warning sign (between the roundabout and the Northaw gateway feature) with a road hump warning sign (on a yellow backing board) and appropriate distance plate.
Repeat the road hump warning sign and distance plate on the opposite side of Judges Hill (facing southbound traffic).
Extend the length of full height kerb on the Northaw Road West approach to the junction by approximately 8m to improve the carriageway edge definition and reduce the length of the pedestrian crossing route across the access.
The comments recorded above are made with reference to my 20+ years experience in Road Safety Engineering including Road Safety Audit and the design of casualty reduction proposals. They are provided to promote safety related and general improvements considered appropriate to the proposed development layout but do not represent any approval of the scheme proposals. These comments and recommendations should be read in the full context of this Road Safety Review document with particular reference to the Safety Assessment presented on page 1 of the document.

This section displays the trip rate results based on the selected set of surveys and the selected count type (shown just
above the table). It is split by three main columns, representing arrivals trips, departures trips, and total trips (arrivals
plus departures). Within each of these main columns are three sub-columns. These display the number of survey days
where count data is included (per time period), the average value of the selected trip rate calculation parameter (per
time period), and the trip rate result (per time period). Total trip rates (the sum of the column) are also displayed at the
foot of the table.
To obtain a trip rate, the average (mean) trip rate parameter value (TRP) is first calculated for all selected survey days
that have count data available for the stated time period. The average (mean) number of arrivals, departures or totals
(whichever applies) is also calculated (COUNT) for all selected survey days that have count data available for the stated
time period. Then, the average count is divided by the average trip rate parameter value, and multiplied by the stated
calculation factor (shown just above the table and abbreviated here as FACT). So, the method is: COUNT/TRP*FACT. Trip
rates are then rounded to 3 decimal places.

This section displays the trip rate results based on the selected set of surveys and the selected count type (shown just
above the table). It is split by three main columns, representing arrivals trips, departures trips, and total trips (arrivals
plus departures). Within each of these main columns are three sub-columns. These display the number of survey days
where count data is included (per time period), the average value of the selected trip rate calculation parameter (per
time period), and the trip rate result (per time period). Total trip rates (the sum of the column) are also displayed at
the foot of the table.
To obtain a trip rate, the average (mean) trip rate parameter value (TRP) is first calculated for all selected survey days
that have count data available for the stated time period. The average (mean) number of arrivals, departures or totals
(whichever applies) is also calculated (COUNT) for all selected survey days that have count data available for the
stated time period. Then, the average count is divided by the average trip rate parameter value, and multiplied by the
stated calculation factor (shown just above the table and abbreviated here as FACT). So, the method is:
COUNT/TRP*FACT. Trip rates are then rounded to 3 decimal places.

This section displays the trip rate results based on the selected set of surveys and the selected count type (shown just
above the table). It is split by three main columns, representing arrivals trips, departures trips, and total trips (arrivals
plus departures). Within each of these main columns are three sub-columns. These display the number of survey days
where count data is included (per time period), the average value of the selected trip rate calculation parameter (per
time period), and the trip rate result (per time period). Total trip rates (the sum of the column) are also displayed at the
foot of the table.
To obtain a trip rate, the average (mean) trip rate parameter value (TRP) is first calculated for all selected survey days
that have count data available for the stated time period. The average (mean) number of arrivals, departures or totals
(whichever applies) is also calculated (COUNT) for all selected survey days that have count data available for the stated
time period. Then, the average count is divided by the average trip rate parameter value, and multiplied by the stated
calculation factor (shown just above the table and abbreviated here as FACT). So, the method is: COUNT/TRP*FACT. Trip
rates are then rounded to 3 decimal places.

This section displays the trip rate results based on the selected set of surveys and the selected count type (shown just
above the table). It is split by three main columns, representing arrivals trips, departures trips, and total trips (arrivals
plus departures). Within each of these main columns are three sub-columns. These display the number of survey days
where count data is included (per time period), the average value of the selected trip rate calculation parameter (per
time period), and the trip rate result (per time period). Total trip rates (the sum of the column) are also displayed at the
foot of the table.
To obtain a trip rate, the average (mean) trip rate parameter value (TRP) is first calculated for all selected survey days
that have count data available for the stated time period. The average (mean) number of arrivals, departures or totals
(whichever applies) is also calculated (COUNT) for all selected survey days that have count data available for the stated
time period. Then, the average count is divided by the average trip rate parameter value, and multiplied by the stated
calculation factor (shown just above the table and abbreviated here as FACT). So, the method is: COUNT/TRP*FACT. Trip
rates are then rounded to 3 decimal places.
