The Association of British Drivers (ABD) is calling on the government to publish details of accidents occurring at speed camera sites before and after installation.
Transport Minister Alastair Darling has announced that all camera partnerships must make this data available, although the information will not be published until after the next election.
The ABD calls for the following statistics to be made available in full for each and every speed camera site, fixed and mobile:
- Figures for at least three years prior to camera installation (five is preferable) and for every year following installation.
- Separated figures for deaths and serious injuries. The practice of using the easily manipulated and misleading ‘KSI’ (killed or seriously injured) is not acceptable because it can mask increases in deaths where relatively minor injuries have reduced.
- Details of the causes of each accident, in particular the speed of travel of vehicles involved and whether the driver was sober, drug free, licenced, in a legally registered, non stolen vehicle.
- Details of any engineering work carried out at each camera site which may have affected accident rates during the period measured.
- Distance from the camera site that accidents occurred.
- Traffic Volume Data
- Speed survey data including the 85th percentile speed.
ABD chairman Brian Gregory commented: “This should be an opportunity for the public at last to be allowed to see for themselves whether cameras really are having any effect on road safety and to evaluate whether prosecuting 3 million drivers a year has had any worthwhile effect on casualty reduction. There is only one way to evaluate the success of a speed camera. Firstly one has to rule out the effects of other road changes – then one has to look at the death rate before and after for a statistically significant period of at least three years. There is also the issue of ‘regression to mean’ to take into account – i.e. Cameras are installed where an unusually high number of accidents have occurred. One would usually expect accident rates to naturally return to the average for the site in following years without intervention.”
