Arizona
The Arizona Department of Public Safety (DPS) is planning to use automated equipment to enforce speed limits and catch red-light runners on state highways in the first program of its kind in the country. The two-phase program would start with cameras in construction zones and at traffic signals on some highways. Cameras would then be placed at selected locations on Phoenix-area freeways. DPS plans to request proposals for camera-equipped vans to deploy behind barriers at construction zones to enforce speed limits and for cameras to be installed at highway intersections with speed limits of up to 45 miles per hour.
