PHOENIX – New traffic cameras have been activated at four Scottsdale intersections, as city officials and law enforcement search for ways to make driving safer in their city.

Cameras were turned on at Indian School and Hayden roads, Shea Boulevard and 92nd Street, Scottsdale and Pinnacle Peak roads and Frank Lloyd Wright Boulevard and Greenway Hayden Loop.

Two others at Hayden and Thomas roads and McDowell and Scottsdale roads were taken offline, police said.

Traffic engineers pored over collisions data, red light and speed violations, severity of collisions and car volume to determine.

“Speed and red-light running contribute to the majority of our traffic collisions,” Sgt. Ben Hoster told KTAR News 92.3 FM on Thursday.

“If we can help slow people down, get them to obey traffic laws, we can definitely reduce damage and obviously physical injury and possible death.”

The data helped officials learn “where we need help in this city (and) where we’re doing well in this city,” Hoster said.

Drivers will have 30-day grace period to adjust to the cameras’ presence. Warnings will be issued, but not citations for the time being.

If drivers go more than 11 mph over posted speed limits, they’ll trigger the camera flash, Hoster said.

Red-light runners, however, will still be fined. He said the fine was more than $200.
