Summary report of general practices, technology and existing work on enforcement cameras
Red light running has been reduced significantly at monitored sites in Nottingham and West London. In West London, improving obedience has permitted the thresholds for over-running red lights to be reduced from 1.8 sec to 1.2 sec.
RTI reductions have been reported.
Cameras have a proven effectiveness in cutting speeding and RTIs.
On average, the number of killed and seriously injured fell by around 50 per cent at fixed sites, and by around 35 per cent at mobile sites.
The number of vehicles exceeding the speed limited fell by 70 per cent at fixed camera sites.
Recent research says that about 78 of the public support speed cameras.
