1. Approach and Methodology

Context

1.1 This technical background report supports the analysis of how people are

travelling within South East Wales, made in Emerging Conclusions and Chapter

4 of Summary Background.

1.2 The South East Wales Transport Model (SEWTM) is a multi-modal disaggregate

transport model of the South East Wales Area. It comprises highway and public

transport assignment models linked together by a policy-responsive variable

demand model. It was built by a team led by Mott MacDonald between 2015

and 2017 and has a base year of 2015. The model is owned by Welsh

Government, managed by Transport for Wales (TfW) and operated by a team

led by Mott MacDonald.

1.3 The Fully Modelled Area (Figure 1) consists of the local authorities of Neath

Port Talbot, Bridgend, Rhondda Cynon Taf, Vale of Glamorgan, Cardiff, Merthyr

Tydfil, Caerphilly, Blaenau Gwent, Torfaen, Newport and Monmouthshire.

Figure 1: SEWTM Study Area

1.4 The model was built to provide a strategic analysis tool for assessing a wide

variety of transport and policy interventions. In particular, its relative strengths

are to:

understand the current travel patterns and the performance of the

transport system

predict future travel patterns and conditions on the transport network

assess the impacts of possible interventions in the transport system in a

consistent manner

assess the impacts of land use changes such as new housing developments

and employment locations in a consistent manner

provide inputs required for transport appraisals and business case

development

provide data required for development control work

1.5 The SEWTM has been used to identify the patterns underpinning the main

travel movements in the South East Wales Transport Commission (SEWTC)

study area, which covers highway, bus and rail trips.1 This has been done by

investigating movements across eight screenlines in the model.

1.6 It should be noted that SEWTM model outputs used in this report do not

account for the removal of the Severn Bridge tolls. The model is currently being

updated to reflect this. Whilst we expect traffic volumes to have increased as a

result of this change, we do not expect the overall distribution of origin-

destination movements to have been altered.

Screenlines

1.7 Model outputs are summarised based on the screenlines in Figure 2 below. Any

highway, bus or rail trip which crosses these lines was extracted. Details of all

the links included in each screenline are given in Section 9.

1 Walk/cycle trips are represented in the demand model but have not been included in this report.

Figure 2: Baseline Screenlines

Methodology

1.8 Figure 3 shows how the Fully Modelled Area was split into different sectors

(geographical zones). The sector system is largely based on local authority

boundaries in South East Wales.

1.9 Trips were assigned to the transport network based on where they start and

finish (i.e. origin and destination).

1.10 The following analysis was completed:

Trip purpose split of vehicles crossing a screenline at different times of the

day, summarised in Sections 2 and 3

Trip lengths of vehicles crossing a screenline, summarised in Section 4

Modal share of bus, highway and rail crossing a screenline, summarised in

Section 5

Trip lengths of vehicles crossing a screenline at different times of the day,

summarised for each screenline in Section 6

The top five origin-destination movements between sectors crossing a

screenline are identified with coloured arrows in Section .

More detailed analysis of trips crossing a screenline between SEWTM

sectors is shown on choropleth maps in Section 7 and 8. These show trip

numbers in terms of trips per km2 over 24 hours (measured per vehicle for

highway movements and per person for public transport movements)2


Figure 3: Sector System

2 Note that the same logarithmic scales are used for all figures, and that intra-zonal (trips that start and finish within the same model zone) are not included.
