Average speed cameras cut the number of crashes that result in death or serious injury by a third, according to research for the RAC Foundation by Road Safety Analysis.
The report found that on average, the number of fatal and serious collisions decreases by 36% after average speed cameras are introduced and the number of accidents that resulted in any type of personal injury is cut by 16%.
“The indications are that compliance with average speed cameras is generally high; now this research reveals the sizeable impact they can have in reducing death and serious injuries,” said RAC Foundation director Steve Gooding.
“As the cost of technology continues to fall, more and more authorities are considering whether to install average speed cameras and so it will be important to ensure that casualty and compliance data is openly available so we can continue to assess and understand the road safety benefits they deliver.”
At the end of last year there were more than 50 stretches of road that had permanent average speed camera systems, the longest being 159km on the A9 between Dunblane and Inverness in Scotland.
