Operation, Maintenance & Specifications

We manage the operation of more than 400 traffic signals using a computerized system called an Intelligent Transportation System 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.

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.

We also maintain and repair traffic signals, flashing school zones, and illuminated street name signs, as well as inspect the work of contractors constructing new signals.
