12. Transportation Introduction 12.1 This Chapter discusses the assessment of potential environmental effects resulting from the traffic, transport movements and infrastructure associated with the Proposed Development. 12.2 The Chapter describes the consultation that was undertaken during the EIA process and outlines the scope of the assessment and assessment methodology. A summary of the baseline information informing the assessment is also provided. 12.3 Several potential effects resulting from the Proposed Development were minimised in advance of the assessment and where relevant, this is clearly stated. The Chapter reports on the likely significant environmental effects and subsequently, mitigation measures required to prevent, reduce or offset any significant adverse effects, or further enhance beneficial effects. The conclusions are provided both in terms of the residual effects and their significance. 12.4 This Chapter (and its associated figures and appendices) is intended to be read as part of the wider ES with particular reference to the introductory chapters of this ES (Chapters 1 - 5) and Chapter 19: Cumulative Effects Assessment. Legislative Framework National Policy and Legislation National Planning Policy Framework (NPPF, 2019) 12.5 Section 9 of the NPPF (Ref 12.1) focuses on promoting sustainable transport whilst acknowledging that the opportunities to maximise sustainable transport vary within different communities and from rural to urban areas. The NPPF provides guidance on transport infrastructure to facilitate sustainable travel in paragraphs 109 to 111. Local Policy and Legislation Swindon Transport Strategy (2009) and Swindon Local Transport Plan 2011-2026 (LTP3, 2009) 12.6 Swindon LTP3 (Ref 12.2) sets out the transport plans for the borough-based on the sustainable principles of the NPPF. The goals of the LTP3 are set out in Para 2.6.1 and seek to: • “reduce the need to travel; • improve pedestrian and cycle permeability; • provide flexible transport for all, enabling choice for travel demand; • improve choice and reduce dependence on the use of the car; and • improve connectivity of movements around Swindon.” 12.1 12.7 Proposed infrastructure improvements to the highway network, specifically on the M4 Junction 15 and A419 corridor are set out within the Swindon Transport Strategy, which form part of the local growth strategy. It is the additional infrastructure alongside the provision of improved public transport provision that would support the proposed development. Development Plan Swindon Borough Council Local Plan 2026 (SBCLP, 2015) & New Eastern Village SPD (NEV, 2016) 12.8 Transport is one of the Strategic Objectives recognised within Swindon Borough Local Plan (Ref 12.3), particularly “to support Swindon’s growth through the provision of a comprehensive and sustainable transport network that is efficient, safe, affordable, accessible and easy to understand, and offers a genuine choice of modes”. 12.9 Policies TR1 and TR2 of the SBCLP set out how the council will use planning and transport powers to promote sustainable transport to the new developments. 12.10 In addition to the SBCLP, a Supplementary Planning Document (SPD) (Ref 12.4) was adopted for the New Eastern Villages (NEV) on land to the east of the A419. This area is located to the north of the Proposed Development. 12.11 The NEV SPD sets out the local highway network improvements, which is to be delivered as part of the development in the area. These improvements include enhanced provision for pedestrians and cyclists as well as the development of the Southern Connector Road (SCR), a new road corridor linking the NEV with Commonhead Roundabout, providing an alternative link north/south to reduce the impact upon the A419. In addition to the SCR, it is also envisaged that new and improved public transport services further supporting the NEV development would be implemented. Summary of Consultation 12.12 Table 12.1 below provides an overview of the consultation that informed the design of the Proposed Development, the consideration of likely significant effects and the methodology for assessment. 12.2 Summary of Consultation Body / Organisation Date and Form of Summary Contact Consultation Swindon Borough Rob Rossiter 23/02/2018, Pre-Application meeting discussing Council meeting appropriate assessment methodology and access to the strategic model. Swindon Borough Tom 22/03/2018, Swindon SCR meeting to discuss programme Council Campbell meeting and design of the SCR. This meeting also discussed how the Proposed Development could connect into the SCR once complete. Swindon Borough Rob Rossiter 20/09/2018, Transport meeting discussing the study area Council meeting of the junction modelling assessment and required modelling scenarios to assess the impacts of the scheme. Swindon Borough Nigel 29/08/2019, Meeting to discuss submitted Transport Council Atkinson meeting Assessment and outstanding requests for information. Additional information was submitted following the meeting. Swindon Borough Nigel 06/02/2020, Meeting to discuss the public transport Council Atkinson meeting provision for the proposed development Scope of the Assessment 12.13 The scope of the assessment was set out in the EIA Scoping Report submitted to SBC in August 2018. The Scoping Report is included in Appendix 1.1., with the scope of this Chapter summarised below. Not Significant Effects 12.14 Some of the effects resulting from the Proposed Development considered in the EIA Scoping Report were identified as not significant. As such, they are not considered further in this Chapter. The effects not considered are listed below, along with the supporting evidence. Hazardous and dangerous loads on the highway 12.15 The Proposed Development does not contain any land uses that are expected to generate any hazardous or dangerous loads onto the highway network. Therefore, no further assessment is carried out in this Chapter of the ES. Fear and Intimidation 12.16 A separate assessment of Fear and Intimidation was not considered necessary, given that the assessment of Severance and Pedestrian/Cycle Delay and Amenity is included in this Chapter. Any effect on Fear and Intimidation levels is inherently considered as part of the assessment of Severance and Pedestrian/Cycle Delay and Amenity. 12.3 12.17 The Institute of Environmental Management and Assessment’s (IEMA) ‘Guidelines for the Environmental Assessment of Road Traffic’ (Ref 12.6) state that the development impact on Fear and Intimidation of road users is dependent on: • the volume of traffic; • HGV composition; • proximity to people; and/or the lack of protection caused by factors such as narrow pavement widths. 12.18 These factors are all considered within the assessment of the impact on Severance and Pedestrian/Cycle Delay and Amenity. It can be concluded that if there is a low level of Severance and good Pedestrian and Cyclist Amenity on a particular link, that road users will experience a low level of Fear and Intimidation. Post-scoping Opinion 12.19 Following the legal review of the ES and in particular this chapter, due consideration has been given to potential environmental impacts resulting from the changes in traffic volumes and subsequently, the capacity of links and junctions within the local highway network. 12.20 As the detailed capacity assessments of key junction and links are provided in the Transport Assessment (TA) and subsequent addendum notes, it is not considered necessary to reiterate the results in detail within this chapter of the ES. The details of the assessments undertaken are available in the the TA provided in Appendix 12.1 and Transport Technical Notes (TTN) 1 (Traffic Model and Assessment Scenarios) and 4 (Revised Transport Impact Assessment) included in Appendix 12.2 and Appendix 12.3 respectively. 12.21 Notwithstanding the above, it is acknowledged that changes in the traffic volumes as a result of the proposals would have an impact on the capacity of the local junctions/links, and in turn, may potentially lead to the environmental effects such as a change in driver stress and delay. However, and as discussed in detail in the TA and associated TTNs, the results of capacity assessments of junctions/links in the locality of the proposed development suggest that all assessed junctions/links are forecast to operate within their theoretical capacity with the identified impacts being considered as negligible and no strategies mitigating the impacts are required. 12.22 It should also be highlighted that several infrastructure improvement schemes are being delivered by SBC and HE in the area. These schemes, when they come forward, would further contribute to a reduction of any potential environmental impacts resulting from the proposals. 12.23 The TA demonstrates that the local highway network can accommodate the proposed development, with its impacts, where identified, being negligible. Therefore, it is deemed appropriate to conclude that any environmental effects resulting from the changes in the junction/links’ capacity would be negligible. 12.4 Likely Significant Effects 12.24 Some of the environmental effects of the Proposed Development related to transport are considered in other Chapters of the ES. As such, they are not discussed as part of this assessment. These include: • Effects relating to air quality due to an increase in traffic are considered in Chapter 13: Air Quality; • Effects relating to noise due to an increase in traffic are considered in Chapter 14: Noise and Vibration. 12.25
