- Countywide Local Plan Transport Modelling - Phase 3 Technical Note (August 2017)
Phase three of the modelling support work produces a revised local plan development scenario to replace DS scenarios from phase two. In addition a set of mitigation schemes are tested in order to try and mitigate any impacts arising from the local plan development in terms of increased congestion and travel time. Whilst The main objective of this work is on mitigating highway impacts arising from the local plan developments within Buckinghamshire. This study does not supersede or replace any detailed modelling work that has been done or will be required in future in assessment of the impacts of individual developments. The purpose of this note is only to assess cumulative impacts of development and identify areas where these could be considered significant in terms of travel time changes.

Consultants (Jacobs) were commissioned to assess the transport impact of the emerging local plan proposals for the districts within Buckinghamshire, comprising Aylesbury Vale, Chiltern, South Bucks and Wycombe. This report covers the second phase of the work has primarily focussed on identifying improvements to the transport network which may be required in order to mitigate the impacts identified as part of the phase one work, and assessing the extent to which those improvements mitigated the impacts. Three forecast scenarios were developed during the first phase of the Countywide Local Plan modelling support in cooperation with Bucks CC and the district councils that now make up Buckinghamshire Council. These comprised of a 2033 DM scenario which included the projected planning completions to 2033 across Buckinghamshire, as well as committed development (some of which may form part of the local plan proposals), and two DS scenarios which included DM development plus additional non-committed local plan developments across the county. Both DS scenarios included the same mix of local plan development but the location of a new settlement near Haddenham, included in the DS1 scenario, was instead assumed to occur at Winslow in the DS2 scenario. The DM development scenario remains unchanged for the second phase of work, but the DS scenarios have been updated to reflect changes in the preferred options of the local plans; further detail of the forecast scenarios are provided in Table 3-A in section 3 of the following report.

Consultants (Jacobs) were commissioned to assess the transport impact of the emerging local plan proposals for the districts within Buckinghamshire, comprising Aylesbury Vale, Chiltern, South Bucks and Wycombe. This report covers the first phase of work which primarily focuses on the identification of transport related issues in the Aylesbury Vale area to inform the development of potential mitigation options. There are three scenarios for Aylesbury Vale - a "Do- Minimum" (DM) model run (essentially a base line reference case); and two "Do Something" (DS1 & DS2) forecast scenarios - DS1 includes a new settlement location at Haddenham and DS2 includes a new settlement location at Winslow. The report refers only to selected model outputs (Plots). Appendices 1& 2 included all outputs from the model (county wide). Comments on this document are invited alongside the draft plan consultation - follow this link for the online comments form.
The second stage of work may include further model runs with refinements to the development scenarios and transport schemes to mitigate development impacts and contribute to the final submission
