    In 2000, Pima County Department of Transportation Traffic Engineering Division (PCDOT) identified the need to fund improvements to various traffic control devices to keep up with advances in technology.  The goal of the project was to improve public safety by using advances in technology to upgrade PCDOT’s traffic control devices. 

    System upgrades were needed to improve traffic safety and operations, pedestrian safety, speed control, lighting and advance warning.

    Upgrades to PCDOT’s traffic control devices are described below: 
    • Approximately 20% of the County’s 105 traffic signals received upgraded controllers and cabinets, including video detection equipment and fiber optic communication lines.  These upgrades will enable PCDOT Staff to receive real-time data on traffic operations and provide the ability to adjust signal operations as necessary from a remote location.
    • Battery back-ups systems for all traffic signals purchased and installed.
    • Seventeen radar driver speed feedback signs installed in order to reduce speeding and crashes in certain corridors in Pima County. 
    • Twenty-eight solar-powered flashing-warning beacons installed at intersections or locations where noncompliance with traffic control devices were an issue or advance warning was determined helpful.
    • Three High intensity Activated cross WalK (HAWK) signals installed that will improve safety at pedestrian crossings.
    • Two solar-powered streetlights installed in rural locations.
    • Miscellaneous minor safety improvements including 12 Pima County Sheriff’s Department motor pull-out pads
