Framework Traffic Management for Shared Zones in Large Private EstatesAITPM 2014 National Conference
Presented by : Wayne JohnsonSenior Project ManagerGTA Consultants Wayne.johnson@gta.com.au
Introduction• Large private estates include:
• retirement villages • industrial estates • sporting venues and • tourism precincts
• Contains Internal Road Networks• Shared road environment• Shared Zone users:
• Pedestrians and Cyclists• Mobility Scooters• Cars• Delivery and maintenance
vehicles
Introduction• Inconsistency in shared
road treatments
• Causing confusion and misinterpretation of road rules
• Framework traffic management plan - provides best practice guidance .
Characteristics of Large Private Estates• Road Network & Access
• Estates with single access point• Controlled access• Contributes to changed driver behaviour
• Intersection Configuration• Minimal to no controls
used• Unclear priorities• Inconsistent treatments
• Intersections which appeared to operate best contained• No indication of priority• Repeater speed signs• Clear sight lines• No on-road markings• Clear way finding
signage
Characteristics of Large Private Estates
• Local Area Traffic Management (LATM) measures
• speed humps• pedestrian crossings
etc• LATM measures vary
significantly
• Non-standard signage
• A consistent approach is required
Characteristics of Large Private Estates
• Pedestrian Facilities• Variety of treatments• Do not comply with Australian
Standards• Some crossings direct
pedestrians into traffic flow
Characteristics of Large Private Estates
Road Users
Typical Safety Issues
• The RMS Guide to Traffic Generating Developments
• Example:• Housing for aged and disabled person
• 1-2 trips per dwelling per day• 0.1-0.2 trips per dwelling per evening peak hour
• Car parking requirements• 2 spaces per 3 units (residents) and • 1 space per 5 units (visitors)
• Example - retirement village of 600 dwellings• 1200 trips per day; 120 trips per evening peak hour• 400 resident plus 120 visitor parking spaces
Traffic and Car Parking Generation
Shared Zone Practice & Principles
The principle objective of a Shared Zone is to provide an area where the speed of vehicles is at a walking pace, so that they constitute the minimum threat to pedestrians sharing the space.
Conditions of use for Shared Zones are outlined by Austroads and State/ Territory guidelines
• Shared Zones have been in Australia for a considerable period of time and are well documented in both historic and modern guidelines
Shared Zone LegislationNational Best Practice
• Austroads Guide to Traffic Management, Part 8: Local Area Traffic Management
• Shared Zone is declared by the use of regulatory signage.
Shared Zone Legislation
New Zealand Signage
• Commonality amongst the Shared Zone guidelines
• Priority to pedestrians• Safety for pedestrians• Speed limits of 10km/hr• Entry treatments• Restricted car parking and
loading requirements• Approval from road authority required.
Shared Zone Legislation
Purpose: to provide a framework of guidance for the planning, design and management of the traffic and transport environment within private residential,
industrial and tourism/recreational precincts.
Frame Traffic Management Plan
• Pedestrian priority• Self enforced speed• No separation of pedestrian
paths• Strictly marked parking bays• For locations where traffic
>50 vph:• Vehicle priority• Traffic calming devices• Separated pedestrian
routes
Road Design
• It is recommended that all entries to a Shared Zone feature an ‘entry treatment’ providing drivers with visual cues for the changed traffic conditions.
Entry Treatments
Traffic Calming
Preferred Option(Ideal)
*Regularly spaced LATM or curved road alignment*Landscaping*Pavement colour/ texture*No linemarking or kerbs
*Regularly spaced LATM or curved road alignment*Landscaping*Pavement colour/ texture*No linemarking or kerbs
Alternative Option
(Some Separation)
*Separated pedestrian paths and kerbs*Street narrowing*Landscaping*Pavement colour/ texture
*Regularly spaced LATM or curved road alignment*Landscaping*Pavement colour/ texture*No linemarking or kerbs
General Guidance
*Traffic islands and street narrowings are preferred, avoid raised thresholds
*Maximum spacing between LATM should be 50metres on a straight road.
*Limited formal traffic control required
*Seating, landscaping and flush pavements to properties will emphasize the shared street space
*Bollards may be used.

Intersection Design
Signage and Linemarking
• Simplified and uniform scheme
• Follow public street practices
• Uniform Colour (White)
• Standard provision for disability access is detailed in AS/ISO 1428.1-2009 Design for Access and Mobility, General Requirements
DDA and Mobility Access
• On-street parking • Reduces sight
distances • Reduces safety
for pedestrians• Traffic Calming
• Marked Bays in Shared Zones
Car Parking
• Access for emergency vehicles• emergency vehicle widths• turning circles • reporting procedures • contact information
• Clear way-finding signs
• Building numbering
• Consult state fire services for requirements
Emergency Response
• Self enforcing Shared Zones
• Consistent features
• Distinctive features
• Clear signage
• Pedestrian friendly
• Minimum intersection controls
• Follow National/State Standards
Conclusions
Thank you!
