Deaths and serious injuries have fallen by 40% at speed camera locations, research by University College London has revealed. This equates to 100 fewer deaths and 870 fewer serious injuries since cameras were installed. There was an overall reduction in injuries at camera locations of 33%, equivalent to 4,030. The findings pour water on claims by motorists' organisations that cameras do little to improve road safety. UCL's research, carried out on behalf of the Department for Transport, found that average speeds at camera sites fell by around 7%, and that the total number of vehicles speeding dropped by 71%.
