Abstract

In 2000, a system was introduced that allowed eight pilot areas to recover the costs of operating speed and red-light cameras (safety cameras) from fines resulting from enforcement. In 2001, legislation was introduced that allowed the system to be extended to other areas. A national programme was then gradually introduced. In February 2003, the Department for Transport (DfT) published a research report 1 that analysed the effectiveness of the system in the eight pilot areas over the first two years (April 2000 to March 2002). This report updates this analysis to the 24 areas that were operating within the programme over the first three years (April 2000 to March 2003). Only areas operating within the programme for at least a year were included in the analysis. High level results are as follows: • Vehicle speeds were down – surveys showed that vehicle speeds at speed camera sites had dropped by around 7% following the introduction of cameras. At new sites, there was a 32% reduction in vehicles breaking the speed limit. At fixed sites, there was a 71% reduction and at mobile sites there was a 21% reduction. Overall, the proportion of vehicles speeding excessively (ie 15mph more than the speed limit) fell by 80% at fixed camera sites, and 28% at mobile camera sites • Both casualties and deaths were down – after allowing for the long-term trend there was a 33% reduction in personal injury collisions (PICs) at sites where cameras were introduced. Overall, this meant that 40% fewer people were killed or seriously injured. At camera sites, there was also a reduction of over 100 fatalities per annum (40% fewer). There were 870 fewer people killed or seriously injured and 4,030 fewer personal injury collisions per annum. There was a clear correlation between reductions in speed and reductions in PICs • There was a positive cost-benefit of around 4:1. In the third year, the benefits to society from the avoided injuries were in excess of £221million compared to enforcement costs of around £54million • The public supported the use of safety cameras for targeted enforcement. This was evidenced by public attitude surveys, both locally and at a national level. Overall, this report concludes that safety cameras have reduced collisions, casualties and deaths.
