TUCSON, Ariz. -- The Pima County Board of Supervisors has voted to shut down all 11 speed-enforcement cameras in the county.
On Tuesday, the supervisors directed County Administrator Chuck Huckelberry to return to the Board within 30 days with information about a more comprehensive, countywide traffic safety plan.
The county's contract with American Traffic Solutions was awarded in January 2009 and expired Monday.
The program was reviewed by the county Department of Transportation and county Sheriff's Department.
They reportedly found no conclusive evidence that fixed, stand-alone cameras effectively and consistently reduce speeds or crashes because drivers tend to decrease speed near the camera and then accelerate after passing.
ATS began covering the warning signs and turning off the camera strobes at the 11 locations Tuesday. The process should be completed by Wednesday afternoon.
