The number of people killed or seriously injured at safety camera sites in Northern Ireland has halved since their introduction, according to a report in the Belfast Telegraph.
In 2002/03 there were 169 serious collisions at the sites, whereas in 2009 this figure dropped to 76.
Edwin Poots, environment minister, says the decline in areas not covered by cameras is significantly less.
Mr Poots said: "These are significant reductions and a clear demonstration that safety cameras, both fixed and mobile, reduce fatal or serious injury collisions."
The Northern Ireland safety camera scheme was launched in July 2003. Data was collected over the three years immediately prior to the launch and compared with the three years subsequent to the launch.
Neil Greig, director of research and policy at the Institute of Advanced Motorists, said there was an encouraging impact in the years following the roll out of cameras across the UK.
He said: "In the first few years they do tend to deliver but as the road gets safer there are fewer incidents so you don’t make the huge savings but you are managing traffic at a safer level."
