Wellingborough Part 2 Local Plan Transport Modelling
Technical note
Introduction
The North Northamptonshire Joint Core Strategy was adopted in July 2016 and
provides the overarching strategic policies for North Northamptonshire. Policies
specific to the local context are provided by Part 2 Local Plans.
The Borough Council of Wellingborough (BCW) has started to prepare their Local
Plan, called the Plan for the Borough of Wellingborough and undertook public
consultation on an Emerging Plan in 2016. Although the housing and employment
figures in the Local Plan are aligned to what is outlined within the Joint Core Strategy,
there have been some refinements, mostly within the town centre.
Northamptonshire County Council worked very closely with the Joint Planning Unit to
forecast the impact of the housing and employment growth outlined within the Joint
Core Strategy on the highway network and identify the infrastructure necessary to
meet the increase in demand.
The infrastructure that was tested in the Northamptonshire Strategic Transport Model
(NSTM) to support the Joint Core Strategy was informed by previous modelling work.
In Wellingborough town centre, the infrastructure requirement drew directly from the
adopted Town Centre Area Action Plan which was based on higher levels of housing
and retail growth in the town centre.
As part of the development of the Plan for the Borough Council of Wellingborough, it
was appropriate to look again at the infrastructure requirements in the town centre,
now a further refinement of the allocated growth in the town centre is known. In
particular, re-looking at the need for the Northern Interceptor and the associated
changes to the one-way system, as well as other infrastructure on the edge of the town
centre such as the north-south link road.
In order to do this, the revised housing, jobs and retail figures were tested to identify
the forecast impact on the highway network.
This technical report outlines the methodology used, the inputs, results and
conclusions that can be drawn from the transport modelling.
Background
The Northamptonshire Strategic Transport Model (NSTM) is Northamptonshire
County Council’s tool for testing major transport and development proposals. It is a full
four stage transport model covering; trip generation, mode choice, trip distribution and
assignment.
2
The demand model (trip generation/mode choice/trip distribution) and the public
transport model are created using EMME31 software. The highway model is created
using a suite of software called SATURN2 (Simulation and Assignment of Traffic to
Urban Road Networks) originally developed by the University of Leeds and since
marketed and developed in association with Atkins.
The model covers the whole of the county, with an increasingly less detailed coverage
beyond the county borders and is created in accordance with guidance issued by the
Department for Transport.
The model is developed for an average weekday (Monday to Friday) in the AM peak
hour (08:00-09:00) and in the PM peak hour (17:00-18:00). All directional link flows
are shown as actual flows and are measured in Passenger Car Units3 (PCUs). The
baseline model year is 2014.
Inputs
Land use and infrastructure assumptions were provided by the BCW for job, housing
and retail completions from 2014 to 2016 and planned growth to 2031. To avoid
having to build an entirely new baseline model at large expense, the completion
figures were included in the 2031 model to capture the sites that have already come
forward. The 2014 baseline model is the same that was used for the baseline Joint
Core Strategy modelling.
Completions and sites under 10 dwellings within Wellingborough were proportioned
across zones within the urban Wellingborough area, as for smaller villages there is
only one base zone to assign the housing to. Windfall and lapse rate housing was
proportioned across all the base year zones in the District.
The total job, housing and retail figures are provided in Table 1 below, with a more
detailed breakdown available in Appendix A.
Table 1: Job, housing and retail figures to 2031
The infrastructure included in the 2031 model is as outlined in Table 2 (which was
identified in the Joint Core Strategy).
As outlined previously, one of the aims of this transport modelling was to identify
whether in light of the revised housing, jobs and retail proposals for the town centre,
there was still a need for the following pieces of infrastructure:
Northern Interceptor Road
Queen Street two-way; and

conversion factor based on Department for Transport guidance

Church Street as bus only
In order to assess the impact on the highway network, these pieces of infrastructure
were not modelled.
Please note that transport modelling for the Joint Core Strategy had already
demonstrated that the Wellingborough Inner Relief Road, also known as north-south
link road, was not required.

The outputs from the transport modelling of the Plan have been interpreted not only
in light of the change from the baseline figures but also by referencing the transport
modelling produced for the Joint Core Strategy. A summary of the actual flow results
grouped by area is described below.
Town centre
As a consequence of modelling no increase in retail within the town centre, there are
lower traffic flows within the town centre compared to the Joint Core Strategy
scenario. As a consequence, fewer junctions have been identified as over capacity in
the town centre in 2031. However there are still some junctions such as Alma Street/
Cannon Street and Midland Road/Victoria Road which are shown to be approaching
capacity in 2031. The transport modelling also highlights in the PM peak that Little
Green is approaching capacity.
The removal of the Northern Interceptor and the associated changes (such as
Church Street becoming bus-only etc.) does not appear to cause any significant
4 Actual flows are shown in Passenger Car Units (PCUs)
5
junction or link issues as it is mitigated to a large extent by the lower retail growth in
the town centre.
Edge of town centre
The infrastructure related to Wellingborough East appears to be showing some
pressure in the transport modelling, however this infrastructure has already been
extensively tested as part of Wellingborough East development and deemed to be
sufficient so this is not a concern. Similarly, some of the infrastructure to the north of
Wellingborough related to Isham bypass and IWIMP is showing some capacity
constraints. Again, Isham bypass and IWIMP has been subject to transport
modelling, and is also being revisited as part of the detailed design of Isham bypass
and designed accordingly, so the highway authority is content that any design
modifications will be picked up through this process.
As expected, both the Embankment and Senwick Road see a decrease in traffic due
to the implementation of the Eastern Relief Road and alternative access points to
Wellingborough East changing the distribution of traffic in this area of the town.
Traffic flows on Finedon Road and Northampton Road stay broadly similar between
2014 and 2031. Traffic flows on Harrowden Road and London Road are forecast to
increase by a similar percentage (26 to 33 percent in the AM peak and 15 to 18
percent in the PM peak).
Principal and strategic network
The greatest increase in two-way traffic flows is on the A509 Park Farm Way which
is a product of the increase in cumulative travel demand between Wellingborough
and Kettering as a result of the proposed growth, and the dualling on this section
which enhances journey times, making a more attractive route to traffic compared to
alternative routes.
Traffic flows on the A45 are broadly in line with those modelled for the Joint Core
Strategy, with traffic flows on the A45 forecast to increase by 12 percent in the AM
peak and 8 percent in the PM peak.
The A45 Wilby Way roundabout and the junctions around Wellingborough and
further afield at Rushden continue to show pressure, possibly a product of improving
flows at Chowns Mill and Rushden Lakes causing issues further along the A45.
Junction performance
Volume over capacity (V/C) is a measure of how congested a particular junction
(node) is and shows the figure for the most congested arm.
Any figures of over 85 percent suggest that the junction is over capacity; figures
between 75 and 85 percent suggest a junction is approaching capacity. Anything
over 100 percent is considered severe congestion. These outputs are useful to
understand where junctions may require an intervention to increase capacity and
improve performance.
6
Table 4 outlines all those junctions in the AM, PM peak or both, where congestion is
forecast to be above 85 percent, which in transport terms is considered to be of most
concern. Only the junctions within the borough of Wellingborough are considered.

Of the junctions identified in Table 4, there are eight junctions where infrastructure
has previously been tested and deemed fit for purpose as part of development
proposals:
Sidegate Lane/ B571
Wellingborough Road/ Sidegate Lane
A510 Northern Way/ A510 Stewart Road

Isham Bypass/ Hill Top Road/ A509 Kettering Road
Isham Bypass Link/ A509 Kettering Road
No further investigation is required at these junctions and the infrastructure in the
Emerging Plan IDP is sufficient.
There are five junctions managed by Northamptonshire County Council which have
been forecast to be over capacity in either the AM, PM or both peaks. These
junctions have been considered in further detail and improvements (if appropriate)
identified in Table 5.
Table 5: Junctions considered for further improvement
Junction Comment Improvement identified
A5193 Harrowden Road/ Pyghtle (Wellingborough)
This is a product of the way traffic is loading onto the network in the model rather than an issue.
No improvement required.
A4500 Main Road/ Mears Ashby Road (Earls Barton)
Only just overcapacity in the PM peak, and is an improvement over the existing modelled situation.
No improvement required.
Broad Green/Hardwick Road (Wellingborough)
This junction has been looked at previously and due to land constraints there is
No improvement required.
8
minimal opportunities for improvement at this location.
A510 Wellingborough Road/ Bell Hill (Finedon)
This is a product of the way traffic is loading onto the network in the model rather than an issue.
No improvement required.
A6/A510 (Finedon) Growth on the A6 and A510 will create pressure at this junction in particular in the PM peak.
Minor improvement may be required to roundabout (minor widening, signing and lining). Cost estimate £100k.
The remaining eight junctions are managed by Highways England. The flows
identified are in line with those identified in the Joint Core Strategy, however advice
should be sought from them regarding any further improvements they deem
necessary.
Conclusion
The transport modelling has demonstrated that the lower traffic flows within the town
centre compared to the Joint Core Strategy scenario results in fewer junctions being
identified as over capacity, however there are still some junctions such as Alma
Street/ Cannon Street and Midland Road/Victoria Road which are shown to be
approaching capacity in 2031 so may require improvement in the next Plan period.
The removal of the Northern Interceptor and the associated changes (such as
Church Street becoming bus-only etc.) does not appear to cause any significant
junction issues as it is mitigated to a large extent by the lower retail growth in the
town centre.
Of the new junctions highlighted as having a capacity issue that are managed by
Northamptonshire County Council, further investigation has identified that only the
A6/A510 junction is deemed to require an improvement.
The other junctions have either been disregarded as an issue due to the way in
which the NSTM models side road junctions, or previous investigations have
identified that there is no feasible scheme available due to land constraints.
