- A review of speed camera evaluations by Cochrane Library including 35 studies from around the world found that average speeds were always reduced when speed cameras were installed. Most countries reporting a 10-35% reduction.
- The number of crashes and related injuries decreased in all 35 of the above studies as well.
- The Cochrane review suggested that “outcomes across all studies show that speed cameras are a worthwhile intervention for reducing the number of road traffic injuries and deaths.”
- A study published in the British Medical Journal found reductions up to 69% for collisions, up to 65% for injuries, and up to 71% for deaths in the immediate vicinity of speed cameras.
- Research conducted by the Center for Transportation Safety of the Texas Transportation Institute found that speeding increases crash risk and severity while speed cameras reduce speeding and crash severity.
- A study conducted by the RAC Foundation found that the use of speed cameras leads to “appreciable reductions in speed…. and substantial reductions in collisions and casualties…”
- A speed camera program in Scottsdale, AZ reduced speeders from 15% to 1-2%. Overall, there was a 95% decrease in the chance of drivers exceeding 75 mph.
- A thorough analysis of the speed camera program in Charlotte, NC found ongoing speed reductions and recommended continued use of speed cameras for safer streets.
- A pilot program in Portland, OR school zones found reduced average and 85th percentile speeds with the use of cameras.
Collisions Reduced By Up To 69%
