Report of the KCC Head of Transportation - Results of the VISUM Transport Modelling


Stephen Whittaker from AMEY provided a presentation on the results of recent VISUM transport modelling. The model projected up to a midpoint of 2022, this being the year of the Local Plan review, and worked on the assumption that 14,034 of the 18,560 independently assessed housing need would be in place by that midpoint.


In response to questions it was explained that:


·  KCC had not worded or approved the Draft Integrated Transport Strategy, however officers at KCC and MBC had been in conversation regarding the contents of the Strategy.


·  The modelling gave a broad network-wide picture, and demonstrated a level of impact on the highway network that would not be regard as severe in the context of the National Planning Policy Framework.


·  Four potential routes for the Leeds-Langley relief road had been identified, but no formal technical work or environmental studies had been undertaken.


·  It was raised that the Draft Integrated Transport Strategy had been expected to come to a special meeting of the Board in January, but this did not occur as Officers and Members were in agreement that this would be too early for the relevant modelling to be completed.


The KCC Head of Transportation advised that an additional paragraph had not been included in the report as the authors had not anticipated the confusion the report would cause. A verbal update was provided as follows:


The modelling undertaken for the 2022 scenario provides Members with a broad network-wide picture in terms of average journey time increases above 2014 levels, and a framework upon which to base the transport strategy over that time period. Members should note that this does not mean that the impact of the 14,043 new dwellings will be the same across the whole network. It also does not mean that individual planning applications can now be considered as acceptable in highway terms, as these must continue to be assessed on their own merits.


For clarity, the position of KCC as Highway Authority as stated in July 2015 that allocating further growth in the south and south east sector of the town would have an unacceptably severe impact on the highway network remains valid. These sectors of the town are the most severely constrained by highway capacity and the most disproportionally affected by the Local Plan proposals for new housing.


As referred to in the report (page 47, paragraphs 4.4 and 5.2) a relief road connecting the A20 to the A274 around Leeds and Langley remains the most effective solution to congestion in this particular part of the town. However, there is a much greater degree of uncertainty concerning the funding and provision of this solution than with the package of local highway improvements in the other sectors of the town. This further emphasises the need for constraint in this area and makes the early completion of the necessary preparatory work for the scheme imperative in the period up to 2022.




1.  That the report be noted.


2.  That the Draft Integrated Transport Strategy be considered at the next available meeting of the Board after the conclusion of consultation.


For – 15  Against – 0  Abstain - 0


3.  That the initial work on options for the Leeds Langley relief road, including potential routes, costings and research on funding, be brought to the meeting of the Board on 20 April 2016.


For – 15  Against – 0  Abstain - 0
