1.0 INTRODUCTION
Brief
1.1 Cole Easdon Consultants Limited (CEC) has been instructed by Taylor Wimpey Exeter (TWE)
to prepare a Transport Assessment (TA) in support of a planning application for the
proposed construction of 105 residential dwellings on land at Raleigh Park, Barnstaple.
Refer to CEC Plan 3882/201 [Location Plan] contained within Appendix 1. The development
proposals are described in further detail within Section 4.0 of this report.
1.2 A Residential Travel Plan prepared by CEC has also been submitted in support of the
application.
Scope
1.3 This TA has been prepared to examine the highway and transportation aspects of the
proposals, including the site’s accessibility by sustainable modes of transport, access and
parking arrangements, the existing accident record in the vicinity of the site, the projected
multi-modal trip generation, and the potential impact of the development on the operation
of the local highway network.
1.4 Detailed discussions have been had with Devon County Council (DCC) as the local highway
authority to inform the scope of this TA.
1.5 Our client’s land at Raleigh Park is one of several sites in the north Barnstaple area that are
subject to planning applications (or have consent) for residential development (refer to CEC
Plan 3882/202 [Committed and other known potential north Barnstaple development sites]
in Appendix 1). These are:
Committed development on land at the North Devon District Hospital - 135 dwellings;
Committed development at the former Laundry Site, Higher Raleigh Road – 14
dwellings;
Land at Trayne Farm (Gleeson) – 80 Dwellings;
Land north of Northfield Lane (Barratt Homes) – 115 dwellings;
Land north of Westaway Plain (Devonshire Homes) – 43 dwellings.
1.6 Assuming that planning permission is forthcoming for all of the above sites, this would give
consent for a total of circa 500 additional new homes in the north Barnstaple area. This TA
considers the combined impact of all of the above developments on the operation of the

Cole Easdon Consultants (CEC) 2 JANUARY 2014
local highway network, even though the last three sites in the list are not committed
developments as such.
1.7 In order to ensure a holistic approach and to ensure that the cumulative transport impacts
of all the various sites are understood, DCC and the various developer teams have co-
operated with respect to the sharing of a variety of transport data, and a common approach
has been agreed with respect to matters such as vehicle trip assignment and junction
impact assessment.
1.8 There has also been co-operation amongst the developer teams with regard to the
investigation of a possible highway improvement scheme at the Westaway Plain / North
Road / North Devon Hospital signal-controlled junction. It is an aspiration of DCC to deliver
an improved junction arrangement at this location in view of the fact that this junction is
currently operating close to its theoretical capacity at peak times, and experiences
significant levels of queuing and delay. This situation is considered to be particularly
problematic in view of the fact that the junction provides access to the North Devon
District Hospital, with regular access by emergency vehicles being necessary.
1.9 To this end, DCC is seeking to formally progress a highway improvement scheme at this
junction through Cabinet, with an aspiration for construction to start in late 2014. DCC is
undertaking all design and junction modelling work in relation to this scheme, which will
seek to provide a design that can accommodate traffic growth associated with future
development in the North Barnstaple area, and that operates within capacity. It has
therefore been agreed between Cole Easdon Consultants Limited and Devon County Council
that this TA need not undertake junction capacity modelling of the existing junction in view
of the ongoing abovementioned work that DCC is carrying out. Notwithstanding this, the
impact of the development on this junction has still been quantified in terms of predicted
increases in vehicle flows during the network peak periods.
Principal Highway and Transport Aspects of Development
1.10 The principal highway and transport-related aspects of the proposed development are as
follows:
Proposed ghost island site access junction off North Road;
Adequate car parking provision to prevent overspill on to surrounding streets;
Cycle parking provision for all dwellings;

Cole Easdon Consultants (CEC) 3 JANUARY 2014
Provision of 2.0 metre wide footways along site access road to facilitate pedestrian
movement;
Provision of a link off the site access road through to the North Devon District Hospital
site boundary to enable future creation of an emergency link through to the hospital;
Submission of a comprehensive Residential Travel Plan setting out a package of
measures designed to encourage greater use of sustainable modes of transport;
Provision of a high quality Travel Information Pack for every dwelling providing a
package of travel information including details of bus services, Devon car share scheme,
and walking and cycling routes;
Provision of over £500 worth of bus tickets per dwelling for travel on Stagecoach bus
services (cost to developer £250 per dwelling);
Provision of a £50 gift voucher provided as part of the Travel Pack (one per dwelling)
redeemable at a local cycle shop;
Provision of financial contributions towards public transport and offsite highway
works/transport schemes, to be included as part of a S106 agreement; and
Provision of commuted sums for highway drainage, TROs, and potentially works to the
cycle way along North Road.
Structure of the Report
1.11 The remainder of this TA is structured as follows:
Section 2.0 describes the site and surrounding highway network;
Section 3.0 provides a review of relevant national and local transport policy;
Section 4.0 describes the development proposals;
Section 5.0 outlines the site’s accessibility by sustainable modes of transport, including
its proximity to local service and facilities, employment, and education;
Section 6.0 sets out the predicted multi-modal trip generation of the proposed
development;
Section 7.0 details the methodology employed to calculate the assignment of vehicular
trips on to the surrounding highway network;
Section 8.0 discusses the scope of the offsite junction modeling that has been
undertaken, and provides details of any assumptions made etc.;
Section 9.0 sets out the results of the offsite junction impact assessments;
Section 10.0 provides an appraisal of personal injury accident data for the local area;
Section 11.0 provides details of the proposed highway and transport mitigation
measures; and
Section 12.0 summarises and concludes the report.

2.0 SITE LOCATION AND LOCAL HIGHWAY NETWORK
Site Location
2.1 The site comprises of land known as Raleigh Park and is located immediately south of the
North Devon District Hospital (NDDH), Barnstaple, as shown within CEC Plan 3882/201
[Location Plan] in Appendix 1.
2.2 It is bound to the north by the NDDH, to the south by residential dwellings and undeveloped
land off Higher Raleigh Road, to the west by the A39 North Road, and to the east by
undeveloped land. The Raleigh Park site has a draft allocation for residential development
within the emerging North Devon Local Development Framework [Bar 6], and the site lies
wholly within the existing settlement boundary.
2.3 Barnstaple town centre is located circa 1.6 kilometres to the south (measured from the
eastern extremity of the site), whilst Barnstaple Railway Station is circa 2.5 kilometres to
the south. The pedestrian entrance to the NDDH off North Road is approximately 630
metres from the eastern edge of the site, meaning that this major local employment site is
within comfortable walking distance. Braunton is 8 kilometres to the west whilst
Ilfracombe is circa 15 kilometres to the north.
Local Highway Network
2.4 The following paragraphs provide a description of the local highway network in the vicinity
of the site. Refer also to CEC Plan 3882/201 [Location Plan], included within Appendix 1.
2.5 The site is situated adjacent to the A39 North Road, which facilitates north-south access
through Barnstaple, providing access to the town centre. Beyond Barnstaple it extends
north to Minehead, continuing along the north Devon coast into Somerset and beyond,
whilst to the south it runs along the north Devon coast to Bideford and continues south into
Cornwall.
2.6 It is a single carriageway road with on-road north and southbound cycle lanes, and footways
along both sides. Views of North Road looking north and south in the vicinity of the site are
shown within Photographs 2.1 and 2.2.

2.7 Some 450 metres to the north of the site, the A39 forms a staggered signal-controlled
junction with Westaway Plain / NDDH access as shown in Photograph 2.2. This junction is
presently operating close to its theoretical capacity at peak times, with associated queuing

along the A39. A controlled pedestrian crossing facility is provided on the A39 (south) arm
of the junction, whilst uncontrolled crossings are provided on the Westaway Plain and NDDH
access arms.
2.8 The S106 agreement associated with the consented residential development at the hospital
includes for works to extend the northbound right-turn lane on the A39 at the Hospital
junction by a distance of some 45 metres. However, we point out that DCC is presently
progressing a formal major highway improvement scheme at this junction, with an
anticipated construction start in autumn 2014. A view of the North Road / Westaway Plain
/ North Devon Hospital junction is shown within Photograph 2.3.
Photograph 2.3: North Road / Westaway Plain / North Devon Hospital Junction
2.9 Some 250 metres to the south of the site is the A39 / Higher Raleigh Road staggered
crossroads junction. To the east, Higher Raleigh Road facilitates access to residential
development south of Raleigh Park, whilst to the west it connects with The Rock at a
priority T-junction.
2.10 Continuing further south, the A39 North Road forms a part signal-controlled junction with
Pilton Quay / St. Georges Road / Raleigh Road, before connecting with Rolle Street / North
Walk at a double roundabout arrangement to the north of the town centre.

2.11 Vehicular access to the site itself will be achieved via the existing agricultural access off
North Road, where this will be upgraded to provide a ghost island right turn lane on North
Road. This matter is discussed further within Section 4.0 of this Transport Assessment.

3.0 NATIONAL AND LOCAL TRANSPORT POLICY
3.1 A full summary of planning policy is provided in the Planning Statement prepared by Origin
3. However, we set out below the relevant transport policies.
3.2 The National Planning Policy Framework (NPPF) states that “all developments that
generate significant amounts of movement should be supported by a Transport Statement
or Transport Assessment. Plans and decisions should take account of whether:
the opportunities for sustainable transport modes have been taken up depending on
the nature and location of the site, to reduce the need for major transport
infrastructure;
safe and suitable access to the site can be achieved for all people; and
improvements can be undertaken within the transport network that cost effectively
limit the significant impacts of the development. Development should only be
prevented or refused on transport grounds where the residual cumulative impacts of
development are severe.
3.3 The Devon and Torbay Local Transport Plan 2011-2026 aims to deliver a transport system
that can meet the area’s economic, environmental and social challenges. It also seeks to
deliver the aspirations of Devon &Torbay Councils, stakeholders, businesses and the public.
3.4 The stated vision for Devon and Torbay is that 'Devon & Torbay will offer business,
communities and individuals safe and sustainable travel choices. The transport system will
help to deliver a low carbon future, a successful economy and a prosperous healthy
population living in an attractive environment. To achieve the vision, the strategy has 5
key objectives:
Deliver and support new development and economic growth;
Make best of the transport network and protect the existing transport asset by
prioritising maintenance;
Work with communities to provide safe, sustainable and low carbon transport choices;
Strengthen and improve the public transport network;
Make Devon the ‘place to be naturally active’.
3.5 The Local Transport Plan identifies a separate Market and Coastal Towns and Rural Devon
Strategy. Barnstaple is one of the identified market towns and is thus covered by this
strategy.

Cole Easdon Consultants (CEC) 9 JANUARY 2014
3.6 There are five transport priorities for the towns and rural areas, where the priorities are to:
Assist in supporting existing and future development of the towns;
Work with the community to demonstrate a low carbon approach to travel;
Improve accessibility by developing a core bus and rail service supported by community
transport;
Make Devon ‘the place to be naturally active’ through investment in the leisure
network; and
Develop an approach to parking policy that supports the vitality of town centres.
3.7 With respect to new development, it is stated that this should be 'located where it will be
well served by existing transport infrastructure and enables local trips to be made by
sustainable modes. In some cases, new development can be a catalyst for change and bring
forward targeted capital interventions that address existing problems and provide better
accessibility. Providing good travel choices reduces the need to travel by car which reduce
pressure on the road network and promotes low carbon travel'.
3.8 We point out that the Raleigh Park site is situated directly adjacent the A39 corridor which
is served by regular bus services providing sustainable linkages with the town centre,
railway station and neighbouring towns. It is also situated directly adjacent to the largest
employment facility in North Devon, this being the North Devon District Hospital. It is likely
that many future residents of the site will work at the hospital and will therefore walk to
work.
3.9 An important transportation project for Devon is the Devon Metro, which will seek to
improve rail links between the county’s towns and Exeter, including enhanced frequency
services on the Exeter-Barnstaple branch line (Tarka Line). Annual passenger usage of
Barnstaple Railway Station has increased by circa 200,000 in the ten-year period between
2002 and 2012, and the LTP acknowledges that overcrowding occurs on peak services
between Exeter and Barnstaple. The Devon Metro project will seek to try and address this
situation through a combination of more frequent and longer trains to enhance capacity.
3.10 In summary, it is considered that the proposed residential development at Raleigh Park will
both comply with and support the aspirations of the Devon & Torbay LTP by offering
opportunities for residents to undertake many journeys by sustainable modes of transport.

3.11 The Draft North Devon and Torridge Local Plan is currently being prepared up to the year
2031. Once adopted this plan will replace the saved policies of both the North Devon Local
Plan, published in 2006, and the Torridge District Local Plan, published in 2004.
3.12 In relation to transportation, the transport vision for North Devon is to provide good
strategic connectivity by (inter alia):
ensuring the operational effectiveness of the strategic road network (A361 and A39) and
other strategic routes, linking the area to the national road network (M5 and A30) and
to Exeter, Plymouth and Cornwall;
maintaining the function of the wider strategic road network within northern Devon;
improving journey times and service quality on the Barnstaple-Exeter rail line linking
northern Devon to Exeter and the wider rail network;
maintaining the function of Bideford as a commercial port;
safeguarding routes and exploring opportunities for the reuse and reinstatement of
former railway lines; and
maintaining and enhancing the function and connectivity of the public rights of way
network within northern Devon.
3.13 The two most relevant transport policies of the North Devon Local Plan are saved policies
TRA1A – Promoting Sustainable Transport Choices - and TRA6 – General Highway
Considerations. Policy TRA1A states that:
a development proposal that will generate a significant amount of travel or have an
impact on the local highway network will only be permitted if it will have good
accessibility to a choice of transport modes including walking, cycling and public
transport in accordance with a transport assessment or statement.
in addition to the above, a non-residential proposal must incorporate a travel plan
that delivers sustainable transport measures.
existing and potential pedestrian and cycle routes will be safeguarded from
development.
3.14 Policy TRA6 implies that development will be only permitted provided that:
provision is made for safe access onto and egress from the highway for all forms of
travel serving the site;
the functioning of the road network or the safety of highway users is not harmed; and
the character and setting of the locality is not harmed by any highway works necessary
to accommodate the level of traffic generated by the development.

4.0 DEVELOPMENT PROPOSALS
The Proposals
4.1 The development proposals comprise the construction of 105 residential dwellings with
associated vehicular access and car parking on land at Raleigh Park, Barnstaple.
Vehicular Access
4.2 Vehicular access to the site will be achieved via a new ghost island priority T-junction at
the location of the existing access off North Road. Refer to CEC Plan 3882/100 [Section 278
Works Location Plan, Engineering Layout and Tracking – Draft] within Appendix 1. A Stage
1 Road Safety Audit is provided within Appendix 4 of this report. The design has been
submitted to DCC for comment in advance, and it has been confirmed that there are no
geometric issues with respect to the proposed junction layout. However, following receipt
of DCC’s comments, some minor alterations were made to the design to improve safety for
cyclists on North Road, as discussed below in paragraph 4.3.
4.3 The design of the access arrangement has sought to retain the existing on-road cycle lanes
along North Road, whilst the existing footway width along the eastern side of North Road
has also been retained. It is proposed to introduce a green surface treatment to the
eastern cycle lane as it crosses the site access junction in order to make drivers turning on
to North Road from the site access road more aware of its presence. Dropped kerbs and
tactile paving will be provided at the junction either side of the access road to facilitate
pedestrian movement across it. A PICADY capacity assessment of the proposed access has
confirmed that it will operate with significant reserve capacity and with minimal queuing
and delay. The relevant PICADY output is included within Appendix 5.
Pedestrian Access
4.4 Pedestrian access to the site will be achieved via the proposed all-purpose access off North
Road. Footways will be provided along either side of the access road, which will tie in with
the existing footways on North Road. A pedestrian link will also be provided through to the
public footpath that extends along the western site boundary and links North Road with
Higher Raleigh Road.
Cyclist Access
4.5 Cyclists will access the site via the proposed all-purpose access off North Road. As part of
the site access design, the existing eastern on-road cycle lane on North Road will receive a

Cole Easdon Consultants (CEC) 13 JANUARY 2014
green surface treatment as it passes the site access junction, in order to make drivers
egressing the site more aware of the presence of cyclists and the cycle lane. An advance
warning sign is proposed to be located at an appropriate point along the site access road, as
shown on the aforementioned Plan. North Road benefits from a formal on road cycle lane
along either side providing a convenient linkage towards the town centre.
Masterplan Layout
4.6 The design of the site layout has sought to discourage on-street parking associated with the
adjacent NDDH by introducing sections of road narrowing (to 4.8m). All of the private roads
within the development will be designed as shared surfaces without footway provision,
which will also serve to discourage on-street parking. We point out that much of the
internal highway layout will have frontage development along it and thus private driveway
accesses at regular intervals. Obviously, the presence of private driveway accesses along
the highway will provide a natural deterrent to on-street parking. Notwithstanding this,
DCC has advised that there is no particular existing problem associated with overspill
parking from the hospital. With respect to the need for any sections of double yellow lines
within the site, these can be confirmed at the detailed design / technical approval stage, in
consultation with DCC.
Emergency Link to NDDH
4.7 Following discussions with DCC and representatives of the NDDH, it is proposed to make
provision for an emergency link from the site access road through to the hospital. To this
end, a 3.0 metre wide link through to the hospital’s southern boundary has been indicated
off the development access road, as shown on the Masterplan.
Highway Drainage
4.8 The highways drainage offered for adoption across the proposed development site will be
restricted to the highway gullies and associated gully lateral connections. Any proposed
new surface water drainage across the site will contain both domestic and highway drainage
and therefore will be offered for adoption as public sewers with South West Water. There
are also existing surface water sewers crossing the development site, which will be
maintained/ diverted as part of the site proposals which will also be utilised to dispose of
the on-site domestic and highway run off. The use of these existing sewers and allowable
discharge rates have been agreed with South West Water.

Car Parking
4.9 Car parking provision is proposed as follows:
1 and 2 bed units – 1 space per dwelling;
3 and 4 bed units – 2 spaces per dwelling.
4.10 It is proposed a total of 156 car parking spaces across the site, either within the curtilage of
individual properties or within parking courts. Additional parking provision will be provided
in the form of garages, where there will be some 15 single garages, 1 double garage, and 8
Flats Over Garages.
4.11 We point out that North Devon District Council does not have any adopted parking standards
at the present time. The above level of provision is however considered appropriate for the
site, and strikes a balance between ensuring that as much parking as possible is contained
within the curtilage of individual properties, whilst also supporting the aims of the
Residential Travel Plan that forms part of this planning application.
Cycle Parking
4.12 Two secure cycle parking spaces will be provided for each dwelling. Cycle parking will be
accommodated within a communal store for the flats, and within garages / garden sheds for
the houses.
Servicing
4.13 CEC Plan 3882/SPA/201 [Refuse Vehicle Swept Path Analysis], included within Appendix 1
provides swept path analysis for a refuse vehicle, and demonstrates that refuse vehicles
will be able to adequately access all of the proposed dwellings.

5.0 ACCESSIBILITY BY SUSTAINABLE MODES OF TRANSPORT
5.1 Both national and local planning policy stress the need for new development to be provided
in locations with good accessibility by non-car modes of transport. This accessibility is a
central feature influencing the overall sustainability of a site, and its potential impacts on
the surrounding transport networks. As stressed by the NPPF, development that is
sustainable should go ahead 'without delay'. This Section sets out the application site’s
accessibility by walking, cycling, and public transport, and demonstrates how it is situated
in a sustainable location. Refer also to CEC Plan 3882/203 [Accessibility Plan], within
Appendix 1.

Access to Schools
5.3 The nearest primary schools to the site are located off Abbey Road approximately 1.4
kilometres from the site. Pedestrian movement to these schools from the site can be
achieved via Westaway Close, Wordsworth Avenue, and then along Mear Top / Littabourne.
A footpath connection links North Road with Westaway Close. It is recognised however,
that this distance would be too far for some younger primary school pupils to walk,
although it would certainly be possible for older children and also staff.
5.4 The nearest secondary school to the site is Pilton Community College at Chaddiford Lane
situated approximately 1.6 kilometres to the west of the site. The most appropriate
walking and cycling route from the site to Pilton Community College would be the same as
that for the primary schools, and then continuing along Bull Hill and Under Minnow Road.
The walking distance to Pilton Community College is considered to be feasible for older
pupils, and would certainly be within a comfortable cycling distance.
Access to Employment
5.5 According to the 2001 census travel to work data, approximately 42% of working people
resident within the Pilton electoral ward also work within Pilton. It is likely that many of
these work at the North Devon District Hospital, a major employer in North Devon. It is
likely that many future residents at Raleigh Park will also work at the hospital and thus will
be ideally located to be able to travel to work on foot, helping to facilitate a sustainable
development. The walking distance to the pedestrian entrance to the hospital on North
Road from the eastern edge of the site is circa 600 metres and therefore within
comfortable walking distance. Additionally, there is potential for a future direct pedestrian
link to be provided between the site and the hospital. Additional employment

opportunities within the Pilton Ward are located at the Pottington Business Park south of
Braunton Road, and at the Two Rivers Industrial Estate, north of Braunton Road.
5.6 Other employment opportunities situated elsewhere within Barnstaple are located within
the town centre, at the Seven Brethren Industrial Estate, and at the Barnstaple Retail Park.
The location of all of the above employment areas are shown on CEC Plan 3882/203
[Accessibility Plan] in Appendix 1.
Walking Accessibility
5.7 The site is considered to offer good overall pedestrian accessibility, with North Road having
footway provision along both sides of the carriageway, providing links to the NDDH, a major
local employment site, as well as nearby bus stops. There are two pedestrian refuge
islands on North Road in the vicinity of the site, one of which is situated adjacent the
pedestrian entrance to the NDDH (refer to Photograph 5.1), some 225 metres north of the
site access, the other being located some 80 metres south of the site. This latter crossing
connects with a public footpath that links North Road with Higher Raleigh Road (east) and is
shown within Photograph 5.2. A controlled pedestrian crossing facility is provided on the
North Road arm of its signalised junction with Westaway Plain / NDDH as shown within
Photograph 5.3.

Cycling
5.8 The application site offers good accessibility by bicycle, with on-road north and southbound
cycle lanes provided along North Road between its junctions with Westaway Plain to the
north, and Pilton Quay near the town centre to the south. There are various other DCC
‘advisory’ cycle routes in and around the north Barnstaple area, as well as small sections of
off-road traffic sections of cycle route adjacent to North Road. The proximity of the site to
the on-road cycle lanes along North Road will help to encourage trips to be made by
bicycle, particularly between the site and town centre.
Public Transport
Bus
5.9 The site is considered to offer good access by public transport, with the nearest bus stops
being situated on North Road adjacent to the pedestrian access to the NDDH. The
northbound bus stop comprises of a bus lay-by arrangement, with timetable information,
whilst the southbound bus stop comprises of a lay-by with a bus shelter and timetable
information. Refer to photographs 5.4 and 5.5. A pedestrian refuge island is located on
North Road in the vicinity of these bus stops to assist east-west movement across North
Road.

5.10 A summary of the bus services available form North Road is provided within Table 5.2. The
20-minute frequency No.19 service is likely to be particularly attractive to residents,
providing a convenient link between the site and Barnstaple town centre. The No. 6 service
serves Barnstaple Bus Station, thereby providing opportunities for public transport
interchange. The availability of the various bus services along North Road will be promoted
as part of the Residential Travel Plan submitted with this planning application. There is
potential for S106 contributions towards transport from this development to be used to
upgrade the bus stops along North Road, if considered desirable by DCC.

Rail
5.11 The nearest railway station to the site is Barnstaple situated approximately 2.5 kilometres
to the south of the site, within comfortable cycling distance. Barnstaple Railway Station
offers some 87 car parking spaces, together with 10 cycle stands (providing space for 20
cycles). The No. 6 bus service along North Road serves Barnstaple Bus Station, which is
within an 800 metre walk of Barnstaple Railway Station. Future residents would therefore
be able to use this bus service to access the railway station sustainably, providing
opportunities for public transport interchange. A summary of the rail services available
from Barnstaple is provided within Table 5.3.

Summary
5.12 This Section has demonstrated that the site offers good accessibility by sustainable modes
of transport, and that there is potential for many journeys to be undertaken by non-car
modes. In particular, future residents will benefit from being in close proximity to the bus
services that operate along the A39 corridor, as well as the on-road cycle lanes that link the
site with Pilton Quay, near the town centre.

6.0 MULTI MODAL TRIP GENERATION
6.1 CEC has interrogated the TRICS 2013(a) database to derive appropriate multi-modal trip
rates for the proposed residential development. TRICS is the industry standard database for
deriving trip generation forecasts for new developments. In addition to the trip rate
information derived from TRICS, CEC has also obtained 2011 census travel to work mode
split data for the Pilton electoral ward. This has enabled the predicted mode splits
produced by TRICS to be compared with local travel to work mode split data. The proposed
TRICS data was submitted to Devon County Council in advance.
6.2 The ‘Residential – Houses Privately Owned’ category was used as the basis of the TRICS
assessment. An upper limit of 300 and a lower limit of 25 dwellings was applied, and the
sites were also filtered according to public transport provision (range between 50 and 90
between 0700 and 1900). Only ‘Suburban Area’ and ‘Edge of Town’ sites were included
within the assessment. Application of these various filters ensured that the selected sites
are reasonably comparable with the application site and are considered to provide a robust
assessment. The full TRICS data is included within Appendix 5 of this report.
6.3 As agreed with Devon County Council, trip generation has been considered for the midweek
AM (0745-0845) and PM (1630-1730) network peak hour periods. Whilst DCC has also
requested consideration of the Saturday network peak hour (1300-1400), CEC has applied
the trip rates for the busiest midweek network peak hour (PM peak) flows to the 1300-1400
Saturday hour to provide a robust assessment. The resultant multi-modal trip rates are
displayed within Table 6.1, with the resulting trip generation displayed within Table 6.2.

Vehicle Occupants (includes driver) 18 67 56 30
6.4 Table 6.2 suggests that the proposed development will generate some 56 two-way vehicle
trips during the AM peak hour and some 64 two-way trips during the PM peak hour. Some
three two-way cycle trips are predicted during each of the peak hours, with some 21
pedestrian trips during the AM peak hour, and 9 two-way trips during the PM peak hour.
6.5 Table 6.3 provides a breakdown of the proportion of trips that each mode accounts for,
based on the derived TRICS data. It can be seen that trips by non-car modes are predicted
to account for approximately 20% of trips during the AM peak hour, and approximately 14%
during the PM peak hour.

Mode AM Peak (0745-0845) PM Peak (1630-1730)

Public Transport 1% 1.5%
Vehicle Trips 57% 65.5%
Vehicle Occupants (includes driver) 23.5% 21.5%
6.6 In order to provide a comparison with the above-discussed TRICS data, CEC has also
obtained ‘Method of Travel to Work’ data for the Pilton electoral ward of Barnstaple from
the 2011 census. The resultant data is summarised within Table 6.4.

6.7 Table 6.4 indicates that the Pilton ward exhibits a lower mode share for car driver trips
than suggested by the TRICS data, and a corresponding higher mode share for sustainable
modes, particularly walking, which accounts for some 31% of work trips (as compared with
15.5% and 9% as suggested by TRICS for the AM and PM peak hours respectively).
6.8 The estimates produced by TRICS therefore provide a robust assessment in terms of vehicle
impact, as the predicted mode share for vehicle trips is higher than suggested by local
census data for the Pilton Ward. The assessment of the vehicular impact of the
development on the operation of the local highway network has therefore been based on
the TRICS trip rates displayed within Table 6.1.

7.0 VEHICLE TRIP ASSIGNMENT
7.1 The assignment of vehicle trips from the development on to the local highway network has
been calculated based on Travel to Work (TTW) data from the 2001 census. TTW data has
been obtained for the Pilton electoral ward, within which the site is located. The
assignment has been based on the data for car drivers only, to ensure a robust assessment.
This methodology is the same as has been employed by other consultants preparing TAs for
other sites in north Barnstaple.
7.2 Some 31% of TTW car driver trips from Pilton are within Pilton itself. It is likely that a
reasonable proportion of these trips would be to the NDDH, which is a major employer in
Barnstaple and indeed North Devon. However, given that the site is immediately adjacent
the hospital, it has been assumed that any TTW trips to the NDDH from the site would be
made on foot / by bicycle. Accordingly, the majority of TTW trips within the Pilton ward
have been assigned to the large employment area south of Braunton Road. It has been
assumed that these trips would travel south along the A39, and then travel south through
the Pilton Quay signalised junction, and then making a right turn onto Rolle Street at the
double roundabout arrangement. In this way, a robust assessment has been undertaken,
since it has been assumed that all of the trips travel through both of these junctions, where
in reality, a portion may route via Pilton Quay, and thus avoid the double roundabouts.
7.3 All other trips have been assigned according to the most logical vehicle routing and as
shown on CEC Figures 3882/201 [Census Derived Vehicle Trip Distribution] and 3882/202
[Development Vehicle Trip Assignment] within Appendix 2. This assignment was submitted
to and agreed with DCC in advance.
7.4 The vast majority of vehicle trips (circa 94%) are predicted to arrive from and depart to the
south, with some 6% arriving from and departing to the north. The majority of employment
opportunities are situated to the south of the site (with the exception of the NDDH), and
therefore it is logical that the majority of peak hour trips to and from the development will
depart to and arrive from the south.
7.5 A small proportion of trips have been assigned along Higher Raleigh Road (west) on the
basis that this road provides a route through to the primary and secondary schools within
Pilton, which may attract some employment trips from the site. The narrowness of this
road however means that it is unlikely to be an attractive route for drivers.

8.0 HIGHWAY IMPACT ASSESSMENT SCOPE AND METHODOLOGY
8.1 The scope and extent of offsite junction modelling required for this TA was discussed and
agreed with officers from DCC. It was agreed that the following junctions would be
assessed in terms of capacity:
Higher Raleigh Road / North Road Staggered Crossroads;
North Road / Pilton Causeway / St Georges Road signalised junction;
Rolle Street / Pilton Causeway / Alexandra Road double roundabout;
Proposed Site Access Junction (Ghost Island priority junction off North Road).
8.2 Analysis has been undertaken for the following time periods:
Midweek 0745-0845
Midweek 1630-1730
Saturday 1300-1400
8.3 Baseline traffic survey data has been undertaken from classified turning counts undertaken
at the various junctions during April 2013, with the exception of the Higher Raleigh Road /
North Road crossroads, which was surveyed during July 2013. The full survey data is
enclosed within Appendix 6 of this report.
8.4 As requested by DCC, the surveyed base flows have been adjusted by a factor of 1.07 to
account for differences in local traffic flows between April and August, where Barnstaple
experiences seasonal variations in traffic flows, particularly along the A39 corridor. To
ensure consistency and for ease of analysis, the same growth factor has been applied to the
surveyed July flows at the Higher Raleigh Road / North Road crossroads, even though the
difference between July and August flows would likely be lower than between April and
August.
8.5 With regard to the Saturday 1300-1400 assessment, DCC requested that an assessment be
made of a school summer holiday Saturday peak hour. DCC provided data from a
permanent ATC located on the A39 North Road. This data provided the daily traffic flows
for every Saturday in 2012 along the A39. This data demonstrates that during the school
summer holidays, Saturday traffic volumes are typically 12% greater than the average flows
recorded on a Saturday in April. However, in view of the fact that the surveyed midweek
flows between 1300 and 1400 are marginally higher than surveyed Saturday 1300-1400
flows, the 12% growth factor has been applied to the 13:00 to 14:00 midweek data to
represent a robust assessment of the likely Saturday summer school holiday traffic flows.

Cole Easdon Consultants (CEC) 28 JANUARY 2014
8.6 All of the junction capacity assessments have been undertaken based on the adjusted
August traffic flows, and therefore represent a robust assessment.
8.7 Analysis has been undertaken for the following scenarios:
2013 Seasonally Adjusted Base
2018 Seasonally Adjusted Base
2018 Adjusted Base + Committed Development
2018 Adjusted Base + Committed Development + Other known north Barnstaple Sites;
2018 Adjusted Base + Committed Development + Other known north Barnstaple Sites +
Raleigh Park Development.
8.8 The 2013 Adjusted Base Flows have been converted to 2018 values using the following
TEMPRO growth factors:
AM Peak – 1.0494
PM Peak – 1.0519
Saturday – 1.0546
Committed Development
8.9 For the purposes of this TA, the only committed development that has been specifically
considered as additional trips is the consented residential development at the former
laundry site off Higher Raleigh Road (14 dwellings). As this TA has not needed to consider
the impact at the Westaway Plain / North Road / NDDH signalised junction, the committed
development around the hospital has not been specifically considered. DCC has also
advised that the proposed Morrisons store should not be regarded as committed
development.
8.10 Of course, the TEMPRO growth factors applied to the 2013 Base Flows to convert to 2018
values means that additional traffic associated with future planned development in
Barnstaple has already been accounted for. For example, in the period between 2013 and
2018, TEMPRO assumes an additional 617 jobs and an additional 654 households for the
Barnstaple area. In reality therefore, the committed development at the former laundry
site (and indeed the other known potential development sites in north Barnstaple) have
already been accounted for within the applied TEMPRO growth factor.

Cole Easdon Consultants (CEC) 29 JANUARY 2014
Other Known North Barnstaple Development Sites
8.11 In addition to the committed development at the laundry site and the growth already
assumed by TEMPRO, CEC has also accounted for additional traffic flows associated with
other possible developments in north Barnstaple, specifically:
Land at Trayne Farm (Gleeson) – 80 dwellings;
Land at Northfield Lane (Barratt Homes) – 115 dwellings.
8.12 We point out that whilst there is also a third potential development site in north Barnstaple
(Land at Westaway Plain – Devonshire Homes) for 43 dwellings, the Transport Statement for
that site did not need to consider any of the offsite junctions that CEC has considered
within this TA. Accordingly, traffic flows from this development have not been specifically
accounted for within the turning movements shown on the CEC Figures contained within
Appendix 2.
8.13 However, as mentioned at paragraph 8.10 above, the 2013 to 2018 TEMPRO growth factors
are considered to more than account for all the planned development in Barnstaple.
Linsig Model of Pilton Causeway / Pilton Quay
8.14 With regard to the LINSIG model of the Pilton Causeway / Pilton Quay / St Georges Road
signalised junction, this has been built based on guidance from DCC who advised that
Saturation Flows within Barnstaple rarely exceed 1,800pcu/hr. The lane saturation flows
were therefore reduced as follows:
Calculated LinSig lane saturation flows above 1900pcu/h were reduced to 1800pcu/h.
Calculated LinSig lane saturation flows between 1900pcu/h and 1800pcu/h were
reduced to 1700pcu/h.
Calculated LinSig lane saturation flows below 1800pcu/h were reduced to 1600pcu/h.
8.15 These saturation flows are considered to provide a robust assessment of the operation of
this signalised junction.
8.16 We reiterate that agreement was reached between Cole Easdon Consultants Limited and
DCC that an assessment need not be undertaken of the North Road / Westaway Plain /
NDDH junction on the understanding that DCC is currently devising an improvement scheme
for this junction which they will seek to secure approval for from Cabinet, with a view for
construction works to potentially start during Autumn 2014. As DCC is preparing their own
redesign of this junction with associated modelling, there was considered to be little merit

in CEC providing a LINSIG capacity assessment of the existing arrangement.
Notwithstanding this, the impact of the proposed Raleigh Park development on this junction
has still been quantified in terms of additional trip numbers, and is discussed within Section
9.0 of the TA.
8.17 The traffic flows associated with the various scenarios are illustrated on CEC Figures 201-
209 within Appendix 2.

9.5 Table 9.2 demonstrates that the Pilton Quay / St. Georges Road junction is presently
operating over capacity in the AM peak. By 2018, the junction is predicted to operate over
capacity during both the AM and PM peaks, albeit with maximum degrees of saturation still
below 100%. The additional traffic associated with the proposed development at Raleigh
Park and the other known north Barnstaple developments causes the maximum degree of
saturation to marginally exceed 100%, with associated reductions in the 'PRC over all links'
value. We point out that the impact of the Raleigh Park development in isolation is

minimal, with the 'PRC over all links' value reducing by a maximum of some 3.8% in the PM
peak.
9.6 In summary, this junction is presently operating over capacity, with its performance
worsening with background traffic growth up to 2018. Beyond 2018, with the impact of the
Raleigh Park development (and other known north Barnstaple developments), its
performance is obviously worsened, though not to any significant degree. The capacity
issues at this junction are presently entirely the result of existing traffic.
9.7 In order to reduce the impact of the proposed development at Raleigh Park on this
junction, a compressive Residential Travel Plan has been submitted which seeks to achieve
reductions of some 20% on the vehicular trip generation predicted within Section 6.0. As
part of the strategy to achieve this reduction in trips, residents will be provided with circa
£500 of bus vouchers (per household), as well as a £50 voucher for a local cycle shop, and a
high quality Travel Information Pack. The aim of such measures is to encourage residents
to make sustainable travel choices from the outset, in order to establish good travel habits.
9.8 Additional mitigation will be provided in the form of S106 contributions towards highways
and transport.
9.9 We would also reiterate points made previously within the TA, including that the modal
splits projected by TRICS (and on which these junction capacity assessments are based)
suggest a significantly higher percentage share for vehicle trips for travel to work than
suggested by 2011 census data for the Pilton ward. In reality, the actual volume of vehicle
trips generated by the development during the peak hours is likely to be less than has been
considered with the junction modelling.
9.10 The application of TEMPRO growth and specific allowance for committed and other
development trips constitutes a considerable degree of double counting, bearing in mind
the levels of growth already assumed by TEMPRO for the Barnstaple area for the period
between 2013 and 2018, as discussed within the previous Section.

and with minimal queuing and delay.
Consideration of the North Road / Westaway Plain / NDDH Signalised Junction
9.15 The census-based vehicle trip assignment discussed within Section 7.0 suggests that the
vast majority of trips (some 93.7%) will arrive from and depart to the south along North
Road, meaning that only some 6.3% of trips will arrive from and depart to the north. As a
result, the number of additional vehicle trips that will travel through the North Road /
Westaway Plain junction from the Raleigh Park development will be very low. The greatest
increase in trips through the junction is during the PM peak hour, with an increase of some
5 two-way trips.
9.16 Even if the actual number of additional trips travelling through the junction exceeded the
above estimate by 100% (i.e.10 trips), this increase would still only equate to one
additional trip every 6 minutes. Such increases would have no discernable impact on the
operation of this junction, or indeed any other junctions further north.

9.17 Whilst our client would be willing in principle to contribute financially towards the planned
highway improvement scheme at the Westaway Plain / North Road / NDDH signalised
junction, any such contribution would need to be proportional to the development’s impact
at this location.
9.18 Given the demonstrable minimal impact at this junction, it is considered that the Raleigh
Park development can be developed immediately and that it is not reliant on the delivery
of any improvement scheme at the hospital junction.
Summary
9.19 This Section has demonstrated that the proposed development at Raleigh Park will have a
relatively minor impact on the performance of the offsite junctions considered. Three of
the junctions considered are predicted to operate with reserve capacity under all scenarios
considered. The only junction that is predicted to operate over capacity is the Pilton Quay
/ St. Georges Road junction, where this junction is already operating over capacity in the
PM peak. By 2018 (without development traffic), it will operate over capacity in the AM
Peak as well.
9.20 The impact of the Raleigh Park development on this junction (in comparison with the
impacts of background traffic growth) is considered to be minor. We reiterate that the
impact of the proposed development will be reduced by the Residential Travel Plan, and by
any other schemes that DCC may implement through S106 funds secured from this
development.

Table 10.1 whilst this report, whilst the full data including a Plan showing the accident
locations is included within Appendix 5 of this report.

10.2 There have been a total of 24 personal injury accidents within the study area of which 21
were classified as slight, two as serious, and one as fatal.
10.3 The biggest cluster of accidents is located at and in the vicinity of the Pilton Street / Pilton
Quay / Pilton Causeway / North Road junction where some twelve accidents have occurred,
one of which was classified as serious and one fatal. The accident notes confirm that the
fatal accident occurred as a result of the vehicle passenger’s seatbelt becoming detached
and consequently resulting in the passenger failing forward and banging their head on the
brake lever of a wheel chair opposite. The serious accident occurred as a cyclist
descending along North Road, within the cycle lane past stationery cars, collided with a car
turning right through opposite queuing traffic lane.

10.4 The next biggest cluster of accidents is located at the Westaway Plain / North Road T-
junction, directly adjacent to the North Devon District Hospital site. At this location, there
have been three slight accidents and one serious accident. The serious accident occurred
as a car collided with the rear of a cyclist who was turning right on the A39.
10.5 There has been one slight accident at the Higher Raleigh Road / North Road crossroads.
This was a rear shunt type accident when a vehicle waiting to turn right into Higher Raleigh
Road was struck by a following vehicle.
10.6 We point out that there have been no recorded accidents in the immediate vicinity of the
site, including along the site frontage.
10.7 In general there do not appear to be any particular highway safety issues in the vicinity of
the site or within the study area as a whole.

11.0 MITIGATION
11.1 Mitigation measures in relation to highways and transportation relate primarily to reducing
the number of additional vehicle trips that are generated by the development, so as to
reduce the impact at offsite junctions.
11.2 The primary form of mitigation for the development is the Residential Travel Plan (RTP),
which has been submitted as part of this application. This seeks to reduce the daily and
peak hour vehicular trip generation of the development by some 20%. The RTP seeks to
reduce the vehicle impact of the development by encouraging and promoting greater use of
sustainable modes of transport. This Section of the report does not seek to reproduce the
content of the RTP; however, the salient points are as follows:
Provision of a high quality Travel Information Pack providing a wealth of transport
information including details of local bus services, timetable information, walking and
cycling maps, and details of the proximity of nearby facilities. These Packs will be
prepared by DCC on behalf of the developer, and will be made specific to the Raleigh
Park development;
Provision of a £50 gift voucher (one per dwelling) for a local cycle store, to be
contained with the Travel Information Pack;
Provision of approximately £500 worth of bus tickets per dwelling redeemable on local
bus services. The tickets will be provided by Stagecoach and funded by the developer,
and details of how to obtain the tickets will be provided as part of the Travel
Information Pack;
Appointment of a Travel Plan Co-ordinator to manage, monitor, and implement the
Travel Plan, and to act as the main point of contact;
The setting of targets for the Travel Plan, to seek to achieve a 20% reduction in vehicle
trips, from a surveyed baseline one year after first occupations;
The offer of personalised travel planning advice to all residents, where this service
would be provided by DCC, funded by the developer.
Other transport-related mitigation measures
11.3 Other mitigation will be provided as follows:
Provision of financial contributions towards enhancement / retention of local public
transport services, to be secured as part of a S106 agreement;
Provision of financial contributions towards offsite highway improvements / other
transport schemes, to be secured as part of a S106 agreement;

Proposed coloured surface treatment to the eastern on road cycle lane along the A39
where it will pass the site access junction, to improve safety for cyclists.
11.4 The final details regarding financial contributions will need to be negotiated and agreed as
part of the S106 agreement, following receipt of planning consent. Clearly, however, the
above represents a considerable package of measures, and CEC considers that these provide
more than adequate mitigation for the quantum of development proposed.

12.0 SUMMARY AND CONCLUSIONS
Summary
12.1 This Transport Assessment (TA) has been prepared in support of a planning application for
the proposed construction of 105 residential dwellings on land at Raleigh Park, Barnstaple.
It has been prepared following regular discussions with highway officers from Devon County
Council (DCC).
12.2 The conclusions of this TA are as follows:
the site can achieve a safe vehicular access off the A39 North Road, a preliminary
design of which has been agreed in principle with DCC;
the site’s location directly adjacent the A39 corridor means that it offers very good
access by sustainable modes of transport, and there is potential for a significant
proportion of trips to be undertaken on foot, by cycle, and by public transport;
a Residential Travel Plan has been submitted which seeks to achieve a 20% reduction in
the vehicular trip generation of the site over a 5 year monitoring period. The Travel
Plan includes the provision of circa £500 of bus vouchers per dwelling, in addition to a
£50 cycle voucher and a high quality Travel Information Pack;
the predicted vehicular impact of the proposed development is considered to be
negligible, especially when compared with the effects of background traffic growth
between 2013 and 2018. Minor increases in queues and delays are predicted at the
various offsite junctions considered as a result of the Raleigh Park development;
there do not appear to be any particular highway safety issues in the vicinity of the site
or along the A39 North Road generally;
the site can be developed immediately and is not reliant on the delivery of any major
new infrastructure.
12.3 CEC considers that there are no highway or transportation reasons to preclude the
development as proposed, subject to the implementation of the Residential Travel Plan,
and the agreement of appropriate S106 contributions towards highways and transport.
