Traffic Signal Maintenance and Operation

Report a problemRequest a Study  Road construction and closures

The City of Mesa manages the operation of more than 400 traffic signals using a computerized system called an Intelligent Transportation System (ITS) designed to tie the operation to a single control center. The Transportation Management Center (TMC) is the core of the operation where traffic signals are synchronized, timings are adjusted and protected turning phases are added. Transportation Management Center

The TMC operates in real-time so certain situations can be reacted to right away such as an accident or planned changes can be implemented with construction projects.  

The City of Mesa also maintains and repairs traffic signals, flashing school zones and illuminated street name signs while also inspecting the work of contractors constructing new signals.
