Question

TFL recently notified me of a proposal to fit an Average Speed Camera on the A316 between Hospital Bridge Roundabout and Hogarth Roundabout. The intention is to meet the new Road Safety Action Plan targets. Can you please set out:

(a) How many accidents per year along this stretch result in people being killed and seriously injured (KSI) and (b) What effect the introduction of similar cameras in nearby areas has had on reducing the number of KSIs in percentage terms?

Officers are drafting a response which will be sent shortly.

Written response received on 1 July 2013.

TfL is currently replacing all the obsolete wet film safety cameras in London with digital alternatives. As part of this process average speed cameras are being considered in a small number of locations due to the additional safety benefits. However, no firm decision has yet been made and no formal consultation on these proposals has been undertaken.

One of the locations under consideration is the A316 between the M3 and Hogarth Roundabout. In the last three years along this route, 25 collisions have occurred that resulted in people being killed or seriously injured (KSI collisions). 11 locations along this route have spot speed cameras installed. At these locations, there were nine KSI collisions three years before cameras were installed, reducing to three in the last three years after cameras were installed. The remaining 22 KSI collisions along the route occurred where no safety camera is present.

An average speed camera system was installed on the A13 in 2010, replacing existing wet film spot speed cameras. While KSIs are usually monitored on a rolling three year basis, initial monitoring data shows that, during the 18-month period following the A13 installation, total KSIs reduced by ten (58 per cent); with seven KSIs occurring, compared to the 17 KSIs which occurred in the 18-months prior to installation of the average speed camera system.

TfL would expect a similar level of performance from any new system on the A316, which could reduce KSIs by 13 over three years.
