Deaths and serious injuries down a quarter near speed cameras: RAC Foundation
A new report published today by the RAC Foundation includes analysis which shows that on average the number of fatal and serious collisions in the vicinity of fixed speed cameras fell by more than a quarter (27%) after their installation.
The report, compiled by professor Richard Allsop of University College London, includes analysis of data for 551 fixed speed cameras in nine locations. In addition to the fall in fatal and serious injuries, the analysis shows an average reduction of 15% in personal injury collisions in the vicinity of the cameras.
However the research also highlights 21 camera sites (in these areas) at which, or near which, the number of collisions appears to have risen enough to make the cameras worthy of investigation in case they have contributed to the increases.
The data analysed in the report, Guidance on the use of Speed Camera Transparancy Data, was released in 2011 as part of a government move to make speed camera operations more transparent to the public.
The estimates for collision reduction were made allowing for the more general downward trend in the number of collisions in the nine areas in recent years, and for the effect of regression to the mean at sites where collision numbers were unusually high in the period before the cameras were installed.
The study comes in the wake of the 2011 instruction from government that speed camera data going back to 1990, detailing accident statistics before and after fixed speed cameras were installed, be made publically available.
Since 2011, only 12 out of 36 of the organisations (a mixture of councils, police forces and safer roads partnerships) responsible for the figures have published the information in a format which complies with official DfT guidance.
