8 TRANSPORT
8.1 Introduction
8.1.1 This chapter considers the potential effects of the Proposed Development in terms of transport.
8.1.2 A comprehensive Transport Assessment (TA), which is appended at Appendix 8.1, has been prepared. The TA examines in detail the transport effects of the Proposed Development on the existing transport system and provides the basis for this assessment.
8.2 Assessment Approach
Methodology
8.2.1 The assessment has been based upon the Institute of Environmental Assessment’s Guidelines for the Environmental Assessment of Road Traffic (the IEA Guidelines). The IEA Guidelines suggest in paragraph 3.15 that two broad rules-of-thumb could be used as a screening process to delimit the scale and extent of the assessment. These are:
‘Rule 1 include highway links where traffic flows will increase by more than 30% (or the number of heavy goods vehicles will increase by more than 30%)
Rule 2 include any other specifically sensitive areas where traffic flows have increased by 10% or more.’
8.2.2 These rules-of-thumb form the starting point for the assessment of effects. Specifically sensitive areas under Rule 2 include accident black-spots, conservation areas, hospitals and links with high pedestrian flows.
8.2.3 The significance of the effects of the Proposed Development will be considered in respect of the following subject areas based on the IEA Guidelines:
• Severance • Driver Delay • Pedestrian Delay • Pedestrian Amenity • Fear and Intimidation • Accidents and Safety 8.2.4 Hazardous Loads have not been included because no hazardous loads are expected. This chapter excludes Noise and Vibration which are addressed in Chapter 10 of the ES. Visual Effects are dealt with in Chapter 6. Air Pollution and Dust and Dirt are addressed in Chapter 9. Ecological Effects are addressed in Chapter 7 and Cultural Heritage is dealt with in Chapter 5.
8.2.5 The potential groups and special interests that may be affected by the Proposed Development have been considered and the following list of ‘receptors’ has been identified:
• Sensitive groups including children, elderly and disabled • Accident ‘black spots’ • Highway junctions operating close to or over capacity • People walking • People cycling • Sensitive locations – schools and local centre
CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport
8.2.6 To record the likely significant environmental effects of the Proposed Development, a seven point scale has been used. The Significance Scale in respect of transport is defined in Table 8.1.
Table 8.1: Significance Scale
Criteria Description
Major beneficial Change that would delay the need for planned modification to off-site infrastructure
Moderate beneficial Increased perception of changing conditions that may delay the need for planned modifications to off-site infrastructure
Minor beneficial Perception of changing conditions e.g. reduction in delay
Neutral/not significant No perceivable change
Minor adverse Perception of changing conditions e.g. increase in delay
Moderate adverse Increased perception of changing conditions that may require modifications to off-site infrastructure
Major adverse Change requiring modifications to off-site infrastructure
8.2.7 The Significance Scale is derived from the interaction of receptor sensitivity and magnitude of change of effect. A matrix of Magnitude of Change and Sensitivity of Receptor is set out in Table 8.2.
Table 8.2: Assessment Matrix
Sensitivity of Receptor
High Medium Low Negligible

8.2.10 The above tables have been derived with reference to the IEA Guidelines such that locations in the study area that would experience an increase in traffic flow of 10% or more are considered in respect of Severance, Pedestrian Delay, Pedestrian Amenity and Fear and Intimidation. In respect of Driver Delay, junctions experiencing a notable change in operational performance are considered and in respect of accidents and safety, locations that would experience a slight change to personal injury accident rate are considered. Professional judgement has been exercised in determining the degree of the effect and whether or not an improvement is required and, if required, what the improvement should comprise.

Limitations to the Assessment
8.2.13 It is considered that there are no particular limitations to this assessment.
8.3 Baseline Conditions
Site Description and Context
8.3.1 Old Sarum is located to the north of Portway, approximately 3.5km north of Salisbury City Centre. The general location of Old Sarum is shown in Figure 8.1 with the surrounding local highway network shown in Figure 8.2. The location of the Proposed Development at Old Sarum is shown in Figure 8.3.
Baseline Information
8.3.2 Baseline information collected during the preparation of the TA is recorded in Table 8.5.

Existing Highway Network
8.3.3 Portway is a relatively straight road (following the course of the Portway Roman Road) that connects to the A338 approximately 3km from Old Sarum by means of a roundabout. To the southwest Portway connects to the A345 by means of a roundabout known as the ‘Beehive Roundabout’, which also provides access to the Beehive Park and Ride.
8.3.4 The carriageway of Portway is approximately 6m wide and the road is subject to a 40mph speed limit in the vicinity of Old Sarum. There is a footway on the south side of Portway between the signal controlled junction that provides access to Old Sarum Park and the roundabout that provides access to Castle Gate Business Park.
8.3.5 On the north side of Portway, a footway commences approximately 70m to the west of the signal controlled junction that provides access to Old Sarum Park and leads up to Partridge Way. From
CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport
Partridge Way, there is a shared footway/cycleway to the roundabout that provides access to Castle Gate Business Park; the shared footway/cycleway crosses Portway on the western arm of the roundabout and continues to the A345. The shared footway/cycleway continues along the eastern side of the A345 into Salisbury.
8.3.6 Existing traffic flows (two-way) on Portway at its western end on a weekday are approximately 900 in both the AM and PM peak hours.
Accident Data
8.3.7 Personal Injury Accident (PIA) data has been obtained from Wiltshire Police Constabulary for the surrounding highway network for a 5-year period (2007-2012). The TA found that the accident records do not point to any existing highway safety issues which require more detailed examination.
Traffic Conditions
8.3.8 In order to establish existing traffic conditions in the vicinity of Old Sarum, traffic surveys were undertaken by survey specialists Axiom Traffic Ltd at the following junctions in September 2012.
• A345 / Phillips Lane Beehive Priority Junction South
• A345 / Phillips Lane Beehive Priority Junction North
• A345 / Portway / Park & Ride Beehive Roundabout
• Portway / Ramsbury Drive / Castle Gate Business Park Roundabout
• Portway / Sherbourne Drive / Lancaster Road Signal Controlled Junction
• Portway / Partridge Way Priority Junction
• Portway / Sherbourne Drive / Old Sarum Park Signal Controlled Junction
8.3.9 Classified turning traffic counts and queue length surveys were collected at each of the junctions for each of the following time periods:
• Weekday AM Peak 07:00-10:00
• Weekday PM Peak 16:00-19:00
8.3.10 Automatic Traffic Count (ATCs) were also undertaken at 4 locations on Portway and the A345 for a period of one week recording directional classified vehicle flows and traffic speeds.
8.3.11 The locations of the traffic counts and ATCs are shown in Figure 8.4.
8.3.12 The operational performance of the junctions identified above has been assessed for both the weekday AM and PM peak hours using the 2012 base year turning movements. All the junctions assessed perform within operational capacity in the weekday AM and PM peak hours.
8.4 Likely Significant Effects
Construction
8.4.1 Construction activities will include the building of the dwellings and civil engineering works to provide new roads and associated infrastructure.
CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport
8.4.2 Construction of the Proposed Development will give rise to deliveries of materials and products that will be transported by heavy goods vehicles. In addition there will be on-site operation of construction equipment and plant.
8.4.3 The Proposed Development will generate construction related traffic for a period of approximately 2 years. Inevitably, much of the waste material will be removed from the Application Site in heavy goods vehicles (HGVs) and all construction materials will need to be transported to the construction sites by a range of vehicle types. The design of infrastructure will minimise earthworks, and it is not expected that there will be substantial quantities of soil to be removed from the site.
8.4.4 It is estimated that on a typical day there may be in the order of 20 HGV two-way trips per working day although during periods of peak construction activity the number of movements of construction vehicles may increase significantly. Measures will be put in place as part of the construction management plan to discourage deliveries during peak traffic periods on the highway network. The vast majority of HGV trips will be along the A345, which is in the top tier of the roads classification system which is defined by the Department for Transport as major roads intended to provide large-scale transport links within or between areas.
8.4.5 In addition, there will be construction employees on site, the number of which will vary according to construction activity. It is estimated that during the peak of construction the number of employees may be in the order of 50-75. Many construction companies transport their employees in work buses and therefore the estimated private vehicle generation is unlikely to exceed 50 two-way trips per working day, significantly less than the operational phase of the Proposed Development, which has been modelled in detail.
8.4.6 The effects of construction traffic will be adverse, but likely to be no greater than from the construction of the dwellings that already have planning permission. The construction period is relatively short-term and therefore only temporary in its effects. Traffic management control mitigation measures will be implemented during construction in the form of controls imposed by planning conditions, health and safety requirements and good construction site practices.
Operation
8.4.7 The traffic impact assessment methodology is described fully in Section 6 of the TA. The assessment scenarios and traffic generation estimates are summarised below.
8.4.8 Table 8.6 details the scenarios assessed in the TA for the weekday AM peak hour (08:00-09:00) and weekday PM peak hour (17:00-18:00) time periods. Scenarios have been assessed both with and without the Proposed Development at Old Sarum, both with and without the Core Strategy allocation at Longhedge.

CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport
8.4.9 The Trip Rate Information Computer System (TRICS) has been interrogated to provide comparable vehicular trip generation rates in order to estimate the traffic generation of the Committed Development, Proposed Development and Core Strategy allocation at Longhedge.
8.4.10 Table 8.7 details the estimated traffic generation for the weekday AM peak hour (08:00-09:00), and Table 8.8 the traffic generation for the weekday PM peak hour (17:00-18:00).

8.5.1 Figures 8.5 and 8.6 show the link flows during the weekday AM peak hour (08:00-09:00) and PM peak hour (17:00-18:00) for the surrounding highway network in 2018 both with Committed Development and with Committed Development and the Proposed Development at Old Sarum (scenarios 2 and 3), the difference between the two and the percentage change.
Severance, Pedestrian Delay, Pedestrian Amenity and Fear and Intimidation
8.5.2 It can be seen from Figures 8.5 and 8.6 that the percentage change in link flows on Ramsbury Drive, Portway, the A345 and Philips Lane would be less than 10%. The Magnitude of Change on these links would therefore be Negligible and irrespective of the Receptor, applying the Assessment Matrix, the effect would be Neutral/not significant.
8.5.3 The percentage change in link flows on Sherbourne Drive would be around 15% on the approach to the western access from Portway and around 47% on the approach the eastern access during the AM peak hour. During the PM peak hour the percentage change in link flows would be around 21% on the approach to the western access and around 45% on the approach to the eastern access. The highway
CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport network serving the Proposed Development has been designed to serve mixed-use development, accommodate a bus route and cater for pedestrians and cyclists and it is therefore considered that no further consideration of Severance, Pedestrian Delay, Pedestrian Amenity or Fear and Intimidation in respect of Sherbourne Drive is required as part of this ES.
Driver Delay
8.5.4 In order to determine the effect of the Proposed Development in respect of Driver Delay, junction capacity assessments have been carried out at the key junctions listed below and identified in Figure 8.7 for the weekday AM and PM peak hours.
• A345 / Phillips Lane Beehive Priority Junction South
• A345 / Phillips Lane Beehive Priority Junction North
• A345 / Portway / Park & Ride Beehive Roundabout
• Portway / Ramsbury Drive / Castle Gate Business Park Roundabout
• Portway / Sherbourne Drive / Lancaster Road Signal Controlled Junction
• Portway / Partridge Way Priority Junction
• Portway / Sherbourne Drive / Old Sarum Park Signal Controlled Junction
8.5.5 The junction capacity assessments have used standard transport planning assessment techniques using the Junctions8 and LINSIG computer programs. The geometric parameters of the junctions have been taken from OS mapping, a topographical survey and measurements taken on site.
8.5.6 The ratio of flow to capacity (RFC) or the degree of saturation (Deg of Sat) are the indicators of the likely operational performance of a junction; an RFC value of 0.85 or Deg of Sat of 90% is generally accepted as the threshold over which ‘levels of service’ will begin to deteriorate.
8.5.7 The junction capacity assessments have shown that all of the key junctions would operate within their operational capacity in scenarios 1-3. All of the key junctions except the Beehive Roundabout would operate within their operational capacity in scenarios 4 and 5. Whilst the Beehive Roundabout is shown to be close to its operational capacity, the change to operational performance is considered to be slight. The Magnitude of Change on this junction would therefore be Negligible and, applying the Assessment Matrix, the effect would be Neutral/not significant.
Accidents and Safety
8.5.8 As identified above, the accident records do not point to any existing highway safety issues which require more detailed examination. The highway network serving the Proposed Development has been designed to serve mixed-use development, accommodate a bus route and cater for pedestrians and cyclists. Technical approval for the new infrastructure was obtained from the highway authority which included the necessary road safety audits. It is therefore considered that no further consideration of Accident and Safety is required as part of this ES.
8.6 Mitigation and Enhancement
Construction Phase
8.6.1 Management control mitigation measures will be implemented during construction in the form of controls imposed by planning conditions, health and safety requirements and good construction site practices. Managing the construction effects will also form part of the construction management plan or similar document. The management control mitigation measures will be intended to protect the
CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport environment, amenity and safety of local residents, businesses, the general public and the surroundings in the vicinity of the Proposed Development.
8.6.2 As part of a Construction Environmental Management Plan (CEMP), a construction vehicle routeing regime for access to the construction site will be identified and agreed with the local highway authority to ensure that drivers of construction related vehicles do not use inappropriate routes which are unsuitable by virtue of their width, alignment or character. The CEMP will also consider measures to discourage deliveries during peak traffic periods on the highway network.
Operational Phase
8.6.3 The provision of a ‘welcome pack’ to residents of the Committed Development at Old Sarum has been secured as part of a Section 106 agreement. The welcome pack includes two vouchers per household for adult bicycles, walking and cycling maps and public transport information etc. To encourage sustainable travel, it is proposed that the ‘welcome packs’ would also be distributed to new residents of the Proposed Development.
8.6.4 Wiltshire Council in its role as the local highway authority has indicated that any new planning applications at Old Sarum would be expected to contribute to the Salisbury Transport Strategy in the same way that new housing allocated in the South Wiltshire Core Strategy are required to do so. This is intended to mitigate the wider impacts of the proposed development beyond those localised impacts assessed in the TA.
8.6.5 The cost for delivering the Salisbury Transport Strategy has been estimated at £25.6 million, which is to be recovered on a roof tax type basis, resulting in a cost per dwelling of £3,300. Persimmon Homes has agreed to this level of contribution for additional housing delivered by any new full planning applications at Old Sarum.
8.7 Cumulative Effects
8.7.1 The assessment has accounted for the Committed Development at Old Sarum and the Core Strategy allocation at Longhedge. The highway network serving the Proposed Development has been designed to accommodate future traffic flows, as demonstrated in the TA. There are therefore no further cumulative effects to be taken into account.
8.8 Summary
8.8.1 This chapter assesses the potential effects of the Proposed Development in terms of transport.
8.8.2 A comprehensive Transport Assessment (TA) has been prepared which examines in detail the transport effects of the Proposed Development on the existing transport system and provides the basis for this assessment.
8.8.3 During the construction phase of the Proposed Development, the effects of construction traffic will be adverse, but likely to be no greater than from the construction of the dwellings that already have planning permission as part of the Committed Development. The construction period is relatively short- term and therefore only temporary in its effects. Management control mitigation measures will be implemented during construction in the form of controls imposed by planning conditions, health and safety requirements and good construction site practices.
8.8.4 The Proposed Development during its operational phase will give rise to an increase in travel demand, which will be permanent. The provision of a ‘welcome pack’ to residents of the Committed Development at Old Sarum has been secured as part of a Section 106 agreement. The welcome pack includes two vouchers per household for adult bicycles, walking and cycling maps and public transport information etc. To encourage sustainable travel, it is proposed that the ‘welcome packs’ would also be distributed to new residents of the Proposed Development.
CIR.P.0625 Old Sarum Additional Housing ES 2012 ENVIRONMENTAL STATEMENT Transport
8.8.5 With respect to the wider transport impacts and the requirement for all new residential development to contribute to the Salisbury Transport Strategy, a financial contribution of £3,300 per dwelling will be offered for additional housing delivered by any new full planning applications at Old Sarum.
8.8.6 It is concluded that with the implementation of the mitigation measures outlined within this chapter, whether designed, management control or physical in nature, the additional demand will be safely and satisfactorily accommodated on the local transport network. The overall residual effect of the Proposed Development in transport terms is likely to be neutral/not significant, or beneficial where mitigation measures have a wider benefit.

1. INTRODUCTION
1.1. This Transport Assessment (TA) has been prepared by PFA Consulting on behalf of Persimmon Homes to accompany a number of detailed planning applications for additional housing development at Old Sarum, Salisbury.
1.2. Old Sarum is located to the north of Portway, approximately 3.5km north of Salisbury City Centre. The general location of which is shown in Figure 1 with the surrounding local highway network shown in Figure 2.
1.3. The planning applications will seek to provide an additional 194 dwellings to those 674 dwellings which have the benefit of outline planning consents at Old Sarum.
Relevant Planning History at Old Sarum 1.4. Land at Old Sarum was originally allocated in the Salisbury District Local Plan (June 2003) under Policy H2D for mixed use development including housing, employment, retail, education, recreation and community uses. The Local Plan policy made it clear that the Council were taking a longer term view beyond the plan period alone by planning for a sustainable development, with a first phase of development limited to 630 houses and 6 hectares of employment during the lifetime of the Plan (2011). The release of further phases of development was anticipated post 2011 through future reviews of the Local Plan.
1.5. Outline planning permission was granted in June 2007 for mixed use development comprising residential, employment uses and community facilities and associated infrastructure (Ref: S/2005/0211). The supporting documentation indicated 630 houses, but with areas reserved for ‘post 2011’ development. However, there was no condition restricting the total number of dwellings.
1.6. Following the outline planning permission, detailed consents (Reserved Matters) have been granted for 628 dwellings. As of September 2012 some 390 homes were occupied leaving 238 still outstanding plus 2 dwellings with outline consent that are subject to Reserved Matters.
1.7. Persimmon Homes subsequently acquired the former MOD playing field at Old Sarum and in December 2010 outline planning permission was granted for residential development and public open space (Ref: S/2005/0619). A Condition was attached to the planning permission restricting development to no more than 44 dwellings. The MOD Land will be the subject of a separate Reserved Matters application.
1.8. An Environmental Statement (ES) was prepared to accompany the two outline planning applications (S2005/0211 and S2005/0619) in January 2005. The approved masterplan for the comprehensive development covered by both applications which formed the basis of the ES in 2005 is attached at Appendix A.
Application Sites 1.9. The locations of each of the various sites at Old Sarum for which detailed planning applications are to be submitted are shown in Figure 3.
1.10. The number of dwellings proposed at each of the five sites are as follows:
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 2 of 34 TRANSPORT ASSESSMENT
Local Centre – 30 dwellings Areas 9a & 9b – 40 dwellings Area 10 – 69 dwellings Area 11 – 35 dwellings Area 12 – 22 dwellings
1.11. The above sites allow for the 2 dwellings which have outline consent that are subject to Reserved Matters.
1.12. The planning applications for the first two sites, namely, the Local Centre and Areas 9a & 9b, will be the subject of Reserved Matters applications as they are consistent with the approved Old Sarum masterplans pursuant to the outline planning permissions. The final three sites will be the subject of new full planning applications given that they either fall outside of those areas identified on the approved masterplan for residential development (Areas 11 & 12), or on land identified for development ‘post 2011’ (Area 10).
1.13. The TA has assessed the cumulative impacts assuming that all of the above sites are developed in addition to those committed developments at Old Sarum which includes the MOD Land. This results in a total of 868 dwellings and 6 hectares of employment at Old Sarum.
Scope of Transport Assessment 1.14. The National Planning Policy Framework (NPPF), published in March 2012, states that all developments that generate significant amounts of movement should be supported by a Transport Statement or Transport Assessment (paragraph 32). Paragraph 32 goes on to identify three main elements that decisions should take into account. They are; whether the opportunities for sustainable transport modes have been taken up; whether safe and suitable access can be achieved; and whether improvements can be undertaken within the transport network that cost effectively limits the significant impacts of the development. Development should only be prevented or refused on transport grounds where the residual cumulative impacts of a development are severe.
1.15. The Department for Transport (DfT) published national guidance on the preparation of TAs in March 2007, Guidance on Transport Assessment (GTA). Reference has been made to the GTA throughout the preparation of this TA.
1.16. The importance of early pre-application discussions, in relation to establishing the level and scope of assessment required, is emphasised by the DfT GTA (paragraph 2.1). The GTA (paragraph 2.2) goes on to say that pre-application discussions should be held with the Local Planning Authority and Local Highway Authority, and, where applicable, the Highways Agency.
1.17. PFA Consulting had a number of meetings with officers of Wiltshire Council to identify the main transport issues to be addressed by the TA and agree the proposed TA methodology.
1.18. A public consultation event was undertaken over two days in September 2012 which provided the opportunity for members of the public to look at and discuss the development proposals at Old Sarum. Comments received from the public at the exhibition were analysed and where appropriate have been embraced in the planning applications.

2. TRANSPORT POLICY FRAMEWORK
Overview 2.1. The following provides a brief review of existing and emerging transport planning policy at national and local level, which is considered relevant to the proposed developments at Old Sarum, Salisbury.
National Planning Policy Framework 2.2. National guidance on planning is set out in the document ‘National Planning Policy Framework’ (NPPF) published in March 2012. It sets out the Government’s planning policies for England and how these are expected to be applied. At the heart of the NPPF is a presumption in favour of sustainable development.
2.3. Chapter 4 of the NPPF deals with ‘Promoting Sustainable Transport’. It states that “transport policies have an important role to play in facilitating sustainable development but also in contributing to wider sustainable and health objectives” (paragraph 29). It goes on to say that “the transport system needs to be balanced in favour of sustainable transport modes”. (paragraph 29).
2.4. Paragraph 30 states that “encouragement should be given to solutions which support reductions in greenhouse gas emissions and reduce congestion.”
2.5. The NPPF states that “all developments that generate significant amounts of movement should be supported by a Transport Statement or Transport Assessment” (paragraph 32). It goes on to identify three main elements that decisions should take into account. They are; whether the opportunities for sustainable transport modes have been taken up; whether safe and suitable access can be achieved; and whether improvements can be undertaken within the transport network that cost effectively limits the significant impacts of the development. “Development should only be prevented or refused on transport grounds where the residual cumulative impacts of a development are severe.”
2.6. With regards development that is likely to generate significant movement, the NPPF suggests that plans and decisions should ensure that these developments are located “where the need to travel will be minimised and the use of sustainable travel modes can be maximised” (paragraph 34).
2.7. Paragraph 35 expands on opportunities for the use of sustainable transport modes, stating that: “…developments should be located and designed where practical to:
accommodate the efficient delivery of goods and supplies; give priority to pedestrian and cycle movements, and have access to high quality public transport facilities; create safe and secure layouts which minimise conflicts between traffic and cyclists or pedestrians, avoiding street clutter and where appropriate establishing home zones; incorporate facilities for charging plug-in and other ultra-low emission vehicles; and consider the needs of people with disabilities by all modes of transport.”
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 5 of 34 TRANSPORT ASSESSMENT
2.8. Travel Plans will be a key tool to facilitate this and will be a requirement for developments which generate significant amounts of movement (paragraph 36).
2.9. With regards larger scale development in particular, paragraph 38 states that “planning policies should promote a mix of uses in order to provide opportunities to undertake day-to-day activities including work on site.” The paragraph goes to state that “…key facilities such as primary schools and local shops should be located within walking distance of most properties.”
2.10. Paragraph 56 of the NPPF states that the Government attaches great importance to the design of the built environment, and good design is a key aspect of sustainable development.
Wiltshire and Swindon Structure Plan 2016 2.11. The development plan for Wiltshire contains ‘saved’ policies from the Wiltshire and Swindon Structure Plan 2016, adopted in April 2006. The Structure Plan provides a strategic policy framework for land use planning, development and transport across the administrative areas of Wiltshire (incorporating Wiltshire County and Swindon Borough) up to 2016, and will be replaced by the Wiltshire Core Strategy.
2.12. Chapter 5 of the Structure Plan deals with Transport. Policy T1 requires comprehensive transport plans to be developed for both urban and rural areas of the Plan Area with a view to improving the existing transport infrastructure and reducing the need to travel by private car. Policy T3 seeks to secure an appropriate level of accessible, safe and efficient public transport services to: meet the needs of people without access to private transport; reduce reliance upon the car; serve the identified needs arising from existing and proposed major developments; and contribute to environmentally sustainable development. Policy T5 seeks to provide measures to encourage cycling and walking, and improve safety of these modes in order to offer alternatives to private car use.
South Wiltshire Core Strategy 2.13. The South Wiltshire Core Strategy sets out the Council's spatial vision, key objectives and overall principles for development in the area of the former Salisbury District Council. It was adopted in February 2012.
2.14. The South Wiltshire Core Strategy aims to balance the competing environmental, social and economic pressures by prescribing a sustainable spatial strategy for the future development of South Wiltshire. This will include the location of strategic sites for new housing and employment development, as well as policies with which planning applications will be judged.
2.15. The Strategic Objectives of the South Wiltshire Core Strategy are:
Strategic Objective 1: To ensure south Wiltshire is a place where the role and function of settlements is understood and the location of development addresses the causes and effects of climate change.
Strategic Objective 2: To provide everyone with access to a decent, affordable home. This Strategy makes provision for at least 9,900 new homes in south Wiltshire to meet demand up to 2026. It sets out a plan for an appropriate mix of
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 6 of 34 TRANSPORT ASSESSMENT
types, sizes and tenures, particularly in order to address affordable housing needs. It identifies deliverable strategic sites to ensure there is a rolling five-year supply of housing.
Strategic Objective 3: To deliver a thriving economy which provides a range of job opportunities to match a growing population and where traditionally strong sectors, such as scientific research and development, continue to be world leaders.
Strategic Objective 4: To help people feel safer in their communities and to provide a good access to a range of services and leisure opportunities.
Strategic Objective 5: To deliver new buildings which conserve and complement vernacular traditions and maintain and where possible enhance the built and natural environment.
Strategic Objective 6: To enhance south Wiltshire's place as retail centre that offers something different from the mainstream and to establish tourism as a major sector of the economy.
Strategic Objective 7: To ensure that essential infrastructure is in place to support our communities.
Strategic Objective 8: Where everybody is provided with a viable range of transport choices, which reflect a reduction in the need to travel and help in reducing carbon emissions.
2.16. Core Policy 2 sets out the strategic allocations, which includes 450 dwellings and 8 hectares of employment at a site known as Longhedge (Old Sarum), which is located immediately to the north west of Old Sarum. The policy in respect of Longhedge states; “The introduction of additional dwellings to the Old Sarum area will add a critical mass to secure the delivery and viability of planned and new local facilities to create a more self-contained community based around a neighbourhood centre.”
2.17. The South Wiltshire Core Strategy, essentially a transitional document, will in effect be replaced by the Wiltshire wide Core Strategy when the latter document is adopted. Consequently policies from the adopted South Wiltshire Core Strategy have been incorporated into the Wiltshire Core Strategy Pre-Submission Document (February 2012) which will be the subject of an Examination in Public (EiP) early next year.
Wiltshire Core Strategy 2.18. The Wiltshire Core Strategy will set out the Council’s spatial vision, key objectives and the overall principles for development within the County. The Wiltshire Core Strategy is timetabled for adoption in 2013.
2.19. Relevant transport policies in the Wiltshire Core Strategy Pre-Submission Document (February 2012) include Core Policy 60 (Sustainable Transport), Core Policy 61 (Transport and development), and Core Policy 62 (Development Impacts on the Transport Network).
2.20. Core Policy 60 states that the council will use its planning and transport powers to help reduce the need to travel, and support and encourage the sustainable,
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 7 of 34 TRANSPORT ASSESSMENT
safe and efficient movement of people and goods within and through Wiltshire.
2.21. Core Policy 61 states that new development should be located and designed to reduce the need to travel and to encourage the use of sustainable transport alternatives. In the supporting text, paragraph 6.147 states that the transport impacts of new development need to be assessed in accordance with national guidance in the DCLG/Department for Transport’s ‘Guidance on Transport Assessment’, published in March 2007.
2.22. Core Policy 62 states that developments should provide appropriate mitigating measures to offset any adverse impacts on the transport network.
Wiltshire Local Transport Plan 3 (LTP3) (2011 to 2026) 2.23. The third Wiltshire Local Transport Plan (LTP3) covers the period from March 2011 to March 2026. Due to the coalition government’s changes to the planning system, the council took the decision to reduce the scale and scope of the LTP3. The LTP3 covers the period 2011 to 2016, and includes a one-year implementation plan for 2011/12 and four supporting strategies on car parking; freight; public transport; and road safety. The first of the three year implementation plans to deliver the long-term strategy will begin in 2012/13.
2.24. Paragraph 5.3 of the LTP3 sets out the vision for transport in the County and states:
“Vision - To develop a transport system which helps support economic growth across Wiltshire’s communities, giving choice and opportunity for people to safely access essential services. Transport solutions will be sensitive to the built and natural environment, with a particular emphasis on the need to reduce carbon emissions”.
2.25. A number of local strategic transport objectives have been developed in the LTP3. These include:
“SO2 – To provide, support and/or promote a choice of sustainable transport alternatives including walking, cycling, buses and rail.
SO12 – To support planned growth in Wiltshire and ensure that new developments adequately provide for their sustainable transport requirements and mitigate their traffic impacts.
SO13 – To reduce the need to travel, particularly by private car.
SO14 – To promote travel modes that are beneficial to health.
SO17 – To improve sustainable access to Wiltshire’s countryside and provide a more useable public rights of way network.”
Parking Standards 2.26. Minimum residential parking standards are set out in Table 7.1 of the Wiltshire Local Transport Plan 2011-2026 Car Parking Strategy, published in March 2011. The standards are reproduced in Table 2.1 below:
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 8 of 34 TRANSPORT ASSESSMENT
Table 2.1: Minimum Residential Parking Standards (Source: LTP3) Minimum Car Parking Standards Bedrooms (allocated parking) 1 1 space 2 to 3 2 spaces 4+ 3 spaces Visitor Parking 0.2 spaces per dwelling (unallocated)
Salisbury Transport Strategy 2.27. The Salisbury Transport Strategy (STS), covering the Salisbury and Wilton area, has been developed to support the growth identified in the South Wiltshire Core Strategy. The strategy updates the existing strategy for Salisbury that was developed as part of Wiltshire’s first and second LTPs.
2.28. The STS was required to mitigate the impact of additional demand for transport within the Salisbury and Wilton area up to 2026.
2.29. The primary objectives of the STS are:
To support and help improve the vitality, viability and resilience of Salisbury’s economy. To Support planned growth and ensure that developments provide for their transport requirements and mitigate their transport impacts. To provide, support and promote a choice of sustainable transport alternatives. To minimise traffic delays and disruption, and improve journey time reliability on key routes. To ensure that the Salisbury Transport Strategy is affordable and capable of being delivered.
2.30. An assessment of future transport challenges and issues has been made using forecasts from the Salisbury transport model. The model was developed to represent the travel patterns and network conditions for a 2008 base year. Forecasts of travel and transport network performance were estimated for a 2026 forecast year which assumed the level of development proposed by the Core Strategy and known changes to the transport system.
2.31. The Salisbury transport model was been used to assess the performance of the STS which comprises the following components:
Enhancement of Park and Ride sites Demand management Enhancement to bus services Smarter choices Improvements to walking and cycling infrastructure Traffic management Local highway improvements Intelligent transport systems
2.32. It has been estimated that the cost of delivering the Salisbury Transport Strategy is £25.6 million, which equates to £3,300 per dwelling based on the Core Strategy allocations.

3. EXISTING CONDITIONS
The Location 3.1. The proposed development sites are located at Old Sarum, which is located north of Portway, approximately 3.5km north of Salisbury city centre.
3.2. As set out in section 1 of this TA, the number of dwellings occupied at Old Sarum, as of September 2012, was 390. A total of 284 dwellings remain to be built-out under the existing outline planning consents as have 6 hectares of B1 employment land. A Primary School and Nursery have been built and are operational.
3.3. In addition to the existing development at Old Sarum, there is employment south of Portway comprising a range of B1, B2 and B8 land uses, two small residential developments at Partridge Way and off Green Lane and Salisbury Football Club which is accessed from Partridge Way. To the west of Old Sarum is the Sarum Centre, a Garden Centre and residential care facilities.
3.4. The location of Old Sarum and the surrounding local highway network is shown in Figure 2.
Existing Highway Network 3.5. There are three points of vehicular access to Old Sarum from Portway. The western most access is in the form of a four arm roundabout. The southern arm of the roundabout provides access to Castle Gate Business Park to the south of Portway and the northern arm provides access to Old Sarum. The road that leads into Old Sarum from the roundabout is Ramsbury Drive which will provide the principle access to the future employment development at Old Sarum. Ramsbury Drive connects with Sherbourne Drive which connects with the Portway in the form of a four arm signal controlled junction approximately 260m to the north east of the roundabout. The southern arm of the signal controlled junction provides access to Sarum Business Park. Sherbourne Drive, which routes through Old Sarum connects to Portway in the form of a second four arm signal controlled junction, the southern arm of which provides access to Old Sarum Park. Sherbourne Drive is currently closed to through traffic at its northern most point effectively forming two cul-de-sacs.
3.6. Portway is a relatively straight road (following the course of the Portway Roman Road) that connects to the A338 approximately 3km from Old Sarum by means of a roundabout. To the southwest Portway connects to the A345 by means of a roundabout known as the ‘Beehive Roundabout’, which also provides access to the Beehive Park and Ride.
3.7. The carriageway of Portway is approximately 6m wide and the road is subject to a 40mph speed limit in the vicinity of Old Sarum. In the vicinity of Old Sarum there is a footway on the south side of Portway between the signal controlled junction that provides access to Old Sarum Park and the roundabout that provides access to Castle Gate Business Park.
3.8. On the north side of Portway, a footway commences approximately 70m to the west of the signal controlled junction that provides access to Old Sarum Park and leads up to Partridge Way. From Partridge Way, there is a shared
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 10 of 34 TRANSPORT ASSESSMENT
footway/cycleway to the roundabout that provides access to Castle Gate Business Park; the shared footway/cycleway crosses Portway on the western arm of the roundabout and continues to the A345. The shared footway/cycleway continues along the eastern side of the A345 into Salisbury.
Traffic Surveys 3.9. In order to establish existing traffic levels in the vicinity of the Old Sarum, traffic surveys were undertaken by survey specialists Axiom Traffic Ltd at the following junctions in September 2012.
1. A345 / Phillips Lane Beehive Priority Junction South 2. A345 / Phillips Lane Beehive Priority Junction North 3. A345 / Portway / Park & Ride Beehive Roundabout 4. Portway / Ramsbury Drive / Castle Gate Business Park Roundabout 5. Portway / Sherbourne Drive / Lancaster Road Signal Controlled Junction 6. Portway / Partridge Way Priority Junction 7. Portway / Sherbourne Drive / Old Sarum Park Signal Controlled Junction
3.10. Classified turning traffic counts and queue length surveys were collected at each of the junctions for each of the following time periods:
Weekday AM Peak 07:00-10:00 Weekday PM Peak 16:00-19:00
3.11. Automatic Traffic Count (ATCs) were also undertaken at 4 locations in Lydney for a period of one week recording directional classified vehicle flows and traffic speeds.
3.12. The locations of the traffic counts and ATCs are shown in Figure 4.
3.13. A summary of the results of the traffic counts for both the AM and PM peak hours are reproduced at Appendix B.
Accident Data 3.14. Personal Injury Accident (PIA) data has been obtained from the Wiltshire Police Constabulary for the surrounding highway network for a 5-year period (2007- 2012). Figure 5 shows the locations and severity of each of the accidents recorded within the study area.
3.15. The accident records identify that there have been a total of 11 accidents during the five year period. Tables 3.1 - 3.4 set out an overview of the PIA data within the study area.

3.16. Analysis of the accidents within the study area has shown that seven accidents occurred to the north of the A345 / Portway Junction. Six of these accidents involved vehicles losing control with four out of the six in wet conditions.
3.17. Two accidents occurred along the Portway, the first involving a motorcyclist colliding with a vehicle waiting to turn right. The second accident was caused by a car overtaking a parked vehicle and colliding with another vehicle moving off from a parked location on the opposite carriageway.
3.18. Two accidents occurred south of the Beehive Roundabout along the A345, The first accident involved a car losing control, crossing the centre line of the carriageway. The second accident involved a motorcyclist in heavy traffic overtaking vehicles on the offside.
3.19. The accident records do not point to any existing highway safety issues which require more detailed examination. For all 11 accidents, human error was concluded as the cause of the accident.
Bus Services 3.20. There are a number of regular bus services that operate in the vicinity of Old Sarum. These bus services include the X5 and Activ8, which route along the A345 and can be accessed at bus stops on the southern arm of the ‘Beehive Roundabout’ and the 501, which is the Beehive Park and Ride service.
3.21. Table 3.5 below sets out summary timetable information for bus services X5, Activ8 and 501.

3.22. From January 2012, certain journeys on the 501, Beehive Park and Ride service now enter Old Sarum and turn at the northern end of Sherbourne Drive. The buses run at least twice per hour between 07:00 and 18:40 on weekdays, and between 08:00 and 18:30 on Saturdays and will pick up at any safe point along Sherbourne Drive and Ramsbury Drive, before calling into the Beehive Park and Ride and running direct to Castle Street and Blue Boar Row in the City Centre.
3.23. Bus service 501 enters Old Sarum at the roundabout on the Portway, travels along Ramsbury Drive, turns onto Sherbourne Drive and travels to its northern end where a temporary turning circle has been constructed. The bus turns and travels back to the Portway. In the future, Sherbourne Drive will be opened to through traffic allowing the bus to enter Old Sarum via the eastern signal controlled junction on Portway and travel in an anti-clockwise direction along Sherbourne Drive and Ramsbury Drive back onto Portway at the roundabout. The temporary and future bus routes are shown on Figure 6.
Rail Services 3.24. Salisbury railway station is located approximately 4.5km to the south of the site in the city centre. Salisbury railway station is operated by South West Trains but is also served by services operated by First Great Western.

4. PROPOSED DEVELOPMENT
4.1. The additional housing proposed at Old Sarum for which detailed planning applications are to be submitted are as follows:
Local Centre – 30 dwellings Areas 9a & 9b – 40 dwellings Area 10 – 69 dwellings Area 11 – 35 dwellings Area 12 – 22 dwellings
4.2. The locations of each of above sites are shown in Figure 3. These combined will deliver an additional 194 dwellings to those 674 dwellings (630 + 44) which have the benefit of an outline planning consent. The above sites allow for the 2 dwellings which have outline consent that are subject to Reserved Matters.
4.3. Barton Willmore’s ‘Revised Master Plan’ (Drawing No. MP-01 Rev K), reproduced at a reduced scale at Appendix C, includes for all of the additional housing sites detailed above together with the existing committed developments.
4.4. Each of the development sites would utilise the existing road infrastructure delivered by the extant planning permissions at Old Sarum with all of the sites being accessed from the Portway via Sherbourne Drive.
4.5. The Old Sarum ‘Parameter Plan Access and Circulation’ is provided at Appendix D, this details the pedestrian, cycle and bus routes within the proposed development.
4.6. Wiltshire Council’s car parking standards have changed since the outline approvals at Old Sarum for which maximum car parking standards were applied providing an average ratio of approximately 2 car parking spaces per dwelling.
4.7. The new standards set out in Wiltshire’s ‘Car Parking Strategy’, which formed part of Wiltshire’s Local Transport Plan 2011-16, sets minimum car parking standards. These new standards (See Table 2.1) have been applied to the proposed additional housing at Old Sarum providing an average ratio of 3 car parking spaces per dwelling.
4.8. The following provides a detailed description of each of the additional housing sites at Old Sarum.
Local Centre 4.9. The proposal for a local centre with a convenience store and doctors surgery and 30 apartments, accords with the approved masterplan and S106 legal agreement. The layout shown at Appendix E is based on discussions with commercial developers who are interested in acquiring the site. The layout provides for a total of 97 car parking spaces.
4.10. The local centre is to be the subject of a Reserved Matters application pursuant to the outline planning consent for Old Sarum.
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 15 of 34 TRANSPORT ASSESSMENT
Areas 9a & 9b 4.11. The proposed planning layout for Areas 9a & 9b is shown at Appendix F.
4.12. Areas 9a & 9b form the final phase of the housing within the approved masterplan for Old Sarum but would bring the total number of dwellings above those anticipated by the outline consent.
4.13. A total of 40 dwellings are proposed with a total of 132 car parking spaces.
4.14. Areas 9a & 9b are to be the subject of a Reserved Matters application pursuant to the outline planning consent for Old Sarum.
Area 10 4.15. The proposed planning layout for Area 10 is shown at Appendix G.
4.16. The approved masterplan and development brief for Old Sarum identified this area as land where development could come forward post 2011.
4.17. A total of 69 dwellings are proposed with 158 car parking spaces. To the south- west corner of the site a 3m wide pedestrian/cycle link to the Portway is proposed to ensure good links for pedestrians and cyclists.
Area 11 4.18. The proposed planning layout for Area 11 is shown at Appendix H.
4.19. Area 11 formed part of the area along the northern boundary which was identified as ‘swale land’ in the approved masterplan to provide the necessary sustainable drainage for the development. Following detailed drainage modelling the ponds necessary to drain the scheme have now been provided elsewhere on the site and Area 11 is no longer required for this purpose.
4.20. A total of 35 dwellings are proposed with a total of 108 car parking spaces.
4.21. Details of the drainage strategy are included in a Flood Risk Assessment (FRA), which has been produced by PFA Consulting to support the proposed additional housing at Old Sarum.
Area 12 4.22. The proposed planning layout for Area 12 is shown at Appendix I.
4.23. Area 12 forms part of the ‘Portway’ open space which was originally designed to preserve the remains of a barrow cemetery. The area now proposed for development does not include the barrow group.
4.24. A total of 22 dwellings are proposed with a total of 92 car parking spaces.

5. TRANSPORT SUSTAINABILITY AND ACCESSIBILITY
5.1. A fundamental consideration in all new development is the achievement of sustainability. This covers a broad range of issues, one of the most important of which is the reduction in the need to travel by car. The NPPF states:
“Plans and decisions should ensure developments that generate significant movement are located where the need to travel will be minimised and the use of sustainable transport modes can be maximised.” (Paragraph 34)
5.2. The provision of alternative modes of sustainable transport, the encouragement of opportunities for walking and cycling and the close proximity of employment and other day-to-day facilities to residential areas are the basic elements of achieving transport sustainability.
5.3. As set out in Section 2 of this TA, with regards larger scale development in particular, paragraph 38 of the NPPF states that “planning policies should promote a mix of uses in order to provide opportunities to undertake day-to- day activities including work on site.” The paragraph goes to state that “…key facilities such as primary schools and local shops should be located within walking distance of most properties.” Whilst the planning of Old Sarum pre- dates the NPPF, the development is in accordance with the principles set out in paragraph 38 of the document.
5.4. The Department for Transport’s document ‘Manual for Streets’ states walkable neighbourhoods are typically characterised by having a range of facilities within 10 minutes’ (up to about 800m) walking distance of residential areas which residents may access comfortably on foot. The Institution of Highways and Transportation’s document ‘Providing for Journeys on Foot’ sets out preferred walking distances to key facilities. It identifies maximum preferred walking distances of 2km for commuting.
5.5. Figure 7 provides a local facilities plan. It shows the existing and committed local facilities and land uses in the vicinity of the application sites. The figure shows that the application sites are well located in the context of existing and committed developments, which include a mix of residential, education, employment and leisure land uses.
5.6. It is therefore considered that the close proximity of a range of local facilities and employment opportunities to the application sites would provide for walkable neighbourhoods to develop at Old Sarum particularly given the provision of pedestrian linkages as proposed. In addition to the facilities within walking distance of the application sites, future residents will have the opportunity to cycle into Salisbury utilising dedicated cycle infrastructure or travel by the regular bus service available from bus stops within Old Sarum.
5.7. The provision of a ‘welcome pack’ to residents of Old Sarum has been secured as part of a Section 106 agreement. The welcome pack includes two vouchers per household for adult bicycles, walking and cycling maps and public transport information etc. To encourage sustainable travel, it is proposed that the ‘welcome packs’ would also be distributed to new residents of the proposed development sites.

6. TRAFFIC IMPACT ASSESSMENT METHODOLOGY
General 6.1. This Chapter details the methodology adopted in the assessment of the traffic impact of the proposed additional housing at Old Sarum on the surrounding highway network.
Assessment Years 6.2. In accordance with paragraph 4.47 of DfT’s ‘Guidance on Transport Assessment’, the capacity of the local highway network has been assessed in 2018, corresponding to five years after the anticipated dates of the various planning applications.
Assessment Time Periods 6.3. The following time periods have been assessed in the TA for traffic impact:
Weekday AM Peak Hour (08:00--09:00) Weekday PM Peak Hour (17:00--18:00)
Traffic Growth 6.4. To represent the situation in the 2018 forecast year, traffic growth was applied to the 2012 traffic counts following guidance set out in TAG Unit 3.15.2 ‘Use of TEMPRO data’.
6.5. The DfT published growth forecasts from the National Trip End Model (NTM) was used as the basis, with TEMPRO factors used to tailor the published traffic forecasts to local circumstances.
6.6. The growth factors derived from NTM/TEMPRO for each of the assessment years are set out in Table 6.1, with the growth rate calculations included at Appendix J.
Table 6.1: NTM / TEMPRO Growth Period Growth Factor 2012 to 2018 AM Peak 1.0496 PM Peak 1.0530
Committed Development 6.7. In assessing the transport impacts from committed development the TA has accounted for all developments at Old Sarum including the MOD Land which has outline planning consent.
6.8. The number of dwellings occupied at Old Sarum, as of September 2012, was 390. A total of 240 dwellings remain to be built-out under the existing outline planning consent for the main site. However, 2 of the 240 dwellings are included within the proposed additional housing, and therefore for assessment purposes, the TA has assessed 238 dwellings as committed development on the main site (630-390-2) in addition to the 6 hectares of B1 employment land which has outline consent.
6.9. The MOD Land also has the benefit of outline planning consent for 44 dwellings and is therefore been assessed in the TA as committed development.
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 18 of 34 TRANSPORT ASSESSMENT
6.10. Table 6.2 details those committed developments yet to be built out as assessed in the TA, all of which have been assumed to be completed by the 2018 assessment year.

Areas 9 & 9a 40 units
Area 10 69 units
Area 11 35 units
Area 12 22 units
TOTAL 196 units
South Wiltshire Core Strategy Allocation at Longhedge 6.12. The adopted South Wiltshire Core Strategy has allocated land at Longhedge for mixed-use development. The site is located immediately north of Old Sarum with access to be taken from the A345 north of Beehive Roundabout.
6.13. Table 6.4 details the level of development assessed in the TA for development at Longhedge, all of which has been assumed to be completed by the 2018 assessment year.

Longhedge 8 hectares of B1 Employment (32,000m2 GFA) Note- For employment land the GFA to site area ratio assumed to be 40%
Trip Rates 6.14. The Trip Rate Information Computer System (TRICS) has been interrogated to provide comparable vehicular trip generation rates to be applied to the developments detailed above.
December 2012 G:\Workfiles\P609\REPORTS\P609-DOC01 TA.doc LAND AT OLD SARUM, SALISBURY Page 19 of 34 TRANSPORT ASSESSMENT
6.15. Trip rates were derived for the weekday AM peak hour (08:00-09:00) and weekday PM peak hour (17:00-18:00) time periods for both ‘mixed-private housing’ and ‘industrial estate’ sub land use categories.
Residential 6.16. The site selection criteria that has been applied to the TRICS ‘mixed-private housing’ sub land use category is set out below:
Sites in England only Sites in suburban or edge of town areas Surveys post 2003 Sites between 30 – 250 dwellings Weekend surveys excluded Sites with a density below 100 dwellings per hectare. Excluding repeat surveys
6.17. Tables 6.5 sets out the vehicular trip rates obtained from the TRICS for mixed- private housing for the weekday AM and PM peak hours. A copy of the TRICS output is contained in Appendix K.

Development Traffic Distribution 6.21. The distribution of the development traffic onto the surrounding local highway network was derived from the peak hour traffic counts undertaken at junctions along the Portway undertaken in September 2012.
6.22. The existing residential development at Old Sarum provided the distribution for the future residential developments, with the existing employment south of the Portway at the airfield providing the distribution for the future employment developments.
6.23. Tables 6.9 & 6.10 below detail the % distribution applied to both the future residential and future employment developments at Old Sarum for both peak hour periods. The tables show that the majority of the development traffic will travel to/from the A345 south of Beehive Roundabout.

Spreadsheet Model 6.25. A spreadsheet model has been developed for each of the modelled time periods. Appendix M contains the spreadsheet model for the AM peak hour and Appendix N the spreadsheet model for the PM peak hour.
6.26. The starting point for the spreadsheet model is the observed traffic flows derived from the traffic counts undertaken in 2012 (Scenario 1). 2018 forecasts are then derived by applying NTM/TEMPRO traffic growth factors. Traffic associated with committed developments are then added (Scenario 2) with further traffic added from the proposed additional housing developments at Old Sarum (Scenario 3).
6.27. The additional traffic from the Longhedge Core Strategy allocation has further been added for scenarios ‘with’ and ‘without’ the proposed additional housing developments at Old Sarum (Scenarios 4 & 5).
6.28. Table 6.12 details each of the individual worksheets that comprise the spreadsheet model.

7. HIGHWAY IMPACT
7.1. This chapter of the TA has taken the traffic flows output from the spreadsheet models for each of the scenarios assessed to establish the traffic impact on the operation of the surrounding local highway network.
Modelled Link Flows 7.2. Figures 8 & 9 show two-way link traffic flows on key links on the surrounding highway network derived from the spreadsheet model for each scenario for the weekday AM peak hour (08:00-09:00) and weekday PM peak hour (17:00- 18:00) time periods.
7.3. The traffic flow diagrams show that the proposed additional housing at Old Sarum does not result in significant increases in traffic on the surrounding local highway network in any of the modelled time periods.
Junction Capacity Assessments 7.4. For each scenario the traffic flows derived from the spreadsheet model have been input into junction capacity assessment programs to assess the operation of key junctions along the Portway and the A345.
7.5. The following key junctions have been tested for capacity for the weekday AM and PM peak hours, the locations of which are shown in Figure 10:
1. A345 / Phillips Lane Beehive Priority Junction South 2. A345 / Phillips Lane Beehive Priority Junction North 3. A345 / Portway / Park & Ride Beehive Roundabout 4. Portway / Ramsbury Drive / Castle Gate Business Park Roundabout 5. Portway / Sherbourne Drive / Lancaster Road Signal Controlled Junction 6. Portway / Partridge Way Priority Junction 7. Portway / Sherbourne Drive / Old Sarum Park Signal Controlled Junction
7.6. The junction capacity assessments have used standard transport planning assessment techniques using the Junctions8 and LINSIG computer programs. The geometric parameters of the junctions have been taken from OS mapping, a topographical survey and measurements taken on site.
7.7. The ratio of flow to capacity (RFC) or the degree of saturation (Deg of Sat) are the indicators of the likely operational performance of a junction; an RFC value of 0.85 or Deg of Sat of 90% is generally accepted as the threshold over which ‘levels of service’ will begin to deteriorate.
1. A345 / Phillips Lane Beehive Priority Junction South 7.8. Capacity assessments of the existing priority junction have been undertaken for all scenarios in both the AM and PM peaks using the PICADY module of Junctions8. The results of which are detailed in Tables 7.1 & 7.2 below.

7.13. The results of the capacity assessment indicate that the existing roundabout will operate within its operational capacity in Scenarios 1-3 in both the AM and PM peak hours. The increased traffic from the Longhedge Core Strategy allocation (Scenarios 4 & 5) shows the existing roundabout to be operating close to its operational capacity on the A345 approaches during the AM peak hour and the Portway approach during the PM peak hour, although the additional queuing and delay with the additional housing at Old Sarum is not considered to be severe.

5. Portway / Sherbourne Drive / Lancaster Road Traffic Signals 7.16. Capacity assessments of the existing traffic signals have been undertaken for all scenarios in both the AM and PM peaks using the latest version of LINSIG. The results of which are detailed in Tables 7.9 & 7.10 below.
7.17. The capacity analysis has assumed that the pedestrian stage is called every cycle as are the stages representing the side roads of Ramsbury Drive and Lancaster Road. These stages will only be called if demand for them exists, the capacity analysis can therefore be considered to be ‘worst case’ and a ‘robust’ assessment.

7. Portway / Sherbourne Drive / Old Sarum Park Traffic Signals 7.21. Capacity assessments of the existing traffic signals have been undertaken for all scenarios in both the AM and PM peaks using the latest version of LINSIG. The results of which are detailed in Tables 7.13 & 7.14 below.
7.22. The capacity analysis has assumed that the pedestrian stage is called every cycle as are the stages representing the side roads of Sherbourne Drive and Old Sarum Park. These stages will only be called if demand for them exists, the capacity analysis can therefore be considered to be ‘worst case’ and a ‘robust’ assessment.

movements. The results for the two LINSIG models outline the degree of saturation (Deg of Sat), delay (pcu/hour) and maximum mean queue (pcu) on each approach. The full detailed outputs from the junction capacity assessment programs are available on request.
7.25. The effect on the local road network from the increase in traffic likely to be generated by the proposed additional housing at Old Sarum has been assessed in the TA. The results indicate that the local network could accommodate the additional traffic and operate satisfactorily with no problems of congestion when allowing for traffic growth, committed developments and the strategic Core Strategy allocation at Longhedge.
Salisbury Transport Strategy 7.26. The highway authority has indicated that any new planning applications at Old Sarum would be expected to contribute to the Salisbury Transport Strategy in the same way that new housing allocated in the South Wiltshire Core Strategy are required to do so. This is intended to mitigate the wider impacts of the proposed development beyond those localised impacts assessed in the TA.
7.27. The cost for delivering the Salisbury Transport Strategy has been estimated at £25.6 million, which is to be recovered on a roof tax type basis, resulting in a cost per dwelling of £3,300. Persimmon Homes has agreed to this level of contribution for additional housing delivered by any new full planning applications at Old Sarum.

8. CONCLUSIONS
8.1. This Transport Assessment (TA) has been prepared by PFA Consulting on behalf of Persimmon Homes to accompany a number of detailed planning applications for additional housing development at Old Sarum, Salisbury.
8.2. The planning applications will seek to provide an additional 194 dwellings to those 674 dwellings which have the benefit of outline planning consents at Old Sarum.
8.3. The TA has reviewed both national and local planning policy which indicates that the proposed additional housing at Old Sarum would be in a sustainable location for development which compliments the existing community and makes a contribution to meeting local housing needs of South Wiltshire. The introduction of additional dwellings to Old Sarum will add a critical mass to secure the delivery and viability of planned and new local facilities to create a more self-contained community.
8.4. The TA has shown that sustainable transport opportunities would be available to residents of the proposed new housing, with good pedestrian and cycle links to the existing network of routes surrounding the site, and a regular high frequency bus service to Salisbury City Centre. Furthermore, the mixed-use development at Old Sarum, comprising a primary school, community building, local centre and local employment in addition to the housing will encourage travel by sustainable modes.
8.5. The effect on the local road network from the increase in traffic likely to be generated by the proposed additional housing at Old Sarum has been assessed in the TA. The results indicate that the local highway network in the 2018 assessment year, in both the weekday AM and PM peak hours, could accommodate the additional traffic and operate satisfactorily with no problems of congestion when allowing for traffic growth, committed developments and the strategic Core Strategy allocation at Longhedge.
8.6. With respect to the wider transport impacts and the requirement for all new residential development to contribute to the Salisbury Transport Strategy, a financial contribution of £3,300 per dwelling will be offered for additional housing delivered by any new full planning applications at Old Sarum.
8.7. The overall conclusion from this TA is that there are no transport or highway related grounds for opposing the planning applications for additional housing at Old Sarum.
