The chapter numbers and paragraph numbers refer to sections within the Transport Assessment. 5. Existing Accessibility CCC Comment 1 2.2 5.10. Accident statistics have now been provided within the TA, however this only covers up to June 2017 and is out of date. Currently data up to October 2019 is available. Updated information should be obtained from CCC. This also needs to look at the cluster sites along the route. There is a cluster site on the Madingley Road/ Cambridge Road (Coton junction), the cause of the accidents should be reviewed and investigated to determine whether any additional mitigation can be provided to mitigate the impact of the additional trips as a result of the development. MB Response 2.3 Additional accident records have been obtained from CCC for additional accidents records between July 2017 to June 2019. Table 2.1 shows that there has been no change in accident records at the Coton junction, in particular there have been no Fatal Accidents at this junction. The full additional data is contained in Appendix A. Period Slight Serious Fatal Total Source 2012 - June 2017 6 6 0 12 TA Table 5.1 July 2017-June 2 3 0 5 Appendix A 2019 Table 2.1: Crash Data for the Coton Junction – July 2017 to June 2019 2.5 It is proposed that any consented development has an ongoing monitoring requirement this can include for monies towards a TRO to reduce speed limit at this junction, if this were to assist in providing a road safety benefit. Summary – Forms part of overall monitoring condition, with monies towards a TRO if required. CCC Comment 2 2.6 5.14. Bus number 4 stops at two stops on St Neots Road (old A428). It is proposed to divert this and other bus services into and through the site and in the future. Agreement Page 2 Countryside Properties (UK) Ltd Bourn Airfield (Reference S/3440/18/OL), South Cambridgeshire Technical Note 21: Response to Comments Received from Cambridgeshire County Council (reference 1555) from the service provider should be obtained and included showing that this is agreed, to ensure that improvements to links to the existing stops are not required. AND CCC Comment 3 2.7 5.24 States that the surrounding roads of Highfields and Broadway have footways, however it should be noted that these are not always in a good state and improvements should be made to bring them up to standard and provide good quality sustainable connections to the new development. Further information is required on proposed improvements so this can be included as part of any permission. MB Response 2.8 The use of these stops has been observed and it is not clear there is any usage. A confirmation from the Local Bus Operator has been sought, but it is considered that this could be conditioned, in terms of the requirement discussed within this report to provide local upgrades to the pedestrian connections. 2.9 For the purpose of the S106 Agreement a Local Footway Enhancement Fund will be identified. This will identify monies to be used for footway enhancements within the catchment area shown in Figure 2.1.
