This article from the Arizona Republic was mentioned and triggered some discussion on misc.transport.road.
I thought I’d mention it here in case you might be interested:
Scottsdale’s Loop 101 speed-enforcement cameras met city officials’ expectations in slowing drivers and reducing the severity of freeway collisions during the technology’s 2006 debut, according to a preliminary report released Wednesday.The early data, part of an ongoing analysis by a team of ASU traffic researchers, also suggests photo-enforcement could save Arizona drivers as much as $45 million per year in medical and insurance bills by decreasing the chance for serious wrecks.[...]
According to Washington’s preliminary report:
- The mean speed of drivers on Scottsdale’s camera-controlled stretch of the freeway dropped by 10 mph, from 74 mph to 64 mph under photo-enforcement.
- Depending on the type of wreck, the total number of collisions was reduced by as much as 70 percent based on a comparison to a comparable stretch of the Loop 101 in the West Valley.
- Injuries from rear-end collisions and sideswipe incidents were down, which could translate to more than $45 million saved on accident damage per year.
