    Minutes:

    (1)       Further to Minute 27 of 4 July 2012, the report presented national and local evidence on the benefits of 20mph schemes and recommended a new policy that the County would seek to implement 20mph schemes when there were clear road safety or public health benefits.  Any locally supported schemes that could not be justified in those terms could still be implemented via the Member Highway Fund provided they were implemented as set out in Department for Transport Circular 01/2013.

     

    (2)       The policy would feed into the new Road Casualty Reduction Strategy which was being developed by Highways & Transportation to assist with meeting targets set out in Bold Steps for Kent and delivering the priorities set out in Growth Without Gridlock (GWG).

     

    (3)       In recent years the demand for the implementation of 20mph schemes had been increasing in response to both local and national campaigns.  KCC had been implementing 20mph schemes in Kent and had 50 schemes covering over 800 roads. In addition, all new residential developments were designed to keep traffic at 20mph although they were not always signed as such to avoid unnecessary sign clutter. The County’s current policy allowed the introduction of 20mph schemes at any location where such measures could be justified in crash savings terms or via the Member Highway Fund (MHF) providing they met implementation criteria as set out in DfT Circular 01/2013.

     

    (4)       The DfT published new advice on the implementation of 20mph schemes in its circular 01/2013 in January 2013 which contained guidance on the setting of local speed limits. There were two distinctly different types of 20mph speed restrictions which were limits, which relied solely on signing, and zones which required traffic calming to reduce speeds. Highway Authorities had powers to introduce 20 mph speed limits that applied only at certain times of day. The variable limits might be particularly relevant where a school was located on a major through road that was not suitable for a full-time 20 mph zone or limit.

     

    (5)       The report included details and results of Primary School Speed Reduction Scheme Trials.  Evidence showed that schemes which combined 20mph limits with traffic calming measures to reduce speeds had proved very successful in reducing causalities by around 40% to 60%.  When only signing had been used the overall benefits were significantly less. 

     

    (6)       The current safety record of the existing 20mph schemes in Kent which were a mix of both limits and zones showed that casualties recorded on 20mph roads in Kent as a proportion of all roads were 2% less than the national average.

     

    (7)       From 1 April 2013 Kent County Council became responsible for a number of Public Health functions. One of those was the Health Improvement for the population of Kent – especially for the most disadvantaged.  There was evidence that 20mph schemes did encourage healthier transport modes such as walking and cycling as in Bristol, where preliminary results indicated increases in levels of walking and cycling of over 20%.
