SCOTTSDALE — A new study shows Scottsdale's freeway cameras are slowing down drivers and appear to be reducing the number of crashes and injuries along the city's stretch of Loop 101.
An Arizona State University professor released preliminary findings of Scottsdale's nine-month photo-enforcement trial program Wednesday during a meeting of the program's technical-evaluation committee, which is composed of officials from city, state and federal government agencies.
The analysis showed that the average speed dropped nearly 10 miles per hour through the enforcement zone, and there were fewer crashes and injuries compared with the same period in previous years.
The study also estimated a program saving of up to $45 million a year in accident- and injury-related costs.
It showed that the average 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.
In addition, the number of collisions was reduced by as much as 70 percent, and injuries from rear-end collisions and sideswipe incidents were down, which could translate to more than $45 million saved on accident damage per year.
