Traffic Signal Management

The purpose of the Traffic Signal System Modernization (TSSM) Program is to help move more traffic efficiently on our existing roadways by maximizing the use of existing traffic signal lights already installed. Improved communication with the traffic signals and optimized signal timings can reduce delay and stops for vehicles traveling down main roadways. The goals of the TSSM include:

  • Maximize flow of traffic
  • Reduce traffic delay
  • Reduce fuel consumption and emissions
  • Reduce number of accidents

To accomplish this, three initiatives were implemented as part of the TSSM Program.

Comprehensive Communications Network
Traffic signals can now be remotely maintained and updated through direct communications, allowing for faster maintenance of traffic lights malfunctioning. The Communications Network provides dedicated communications links (via fiber and wireless transmission) to support current and future transportation needs. This direct communications provides staff access to the traffic signals and allows remote troubleshooting, evaluation and updating of traffic signal timings.

Advanced Traffic Control System
All traffic signal controllers have been upgraded, have greater capabilities than our previous controllers and will meet our increasing operational needs by providing the flexibility necessary to implement complex traffic signal timing plans.

Traffic Signal Coordination
All 1,300 traffic signals will be re-timed and coordinated to allow the greatest number of vehicles through a group of signals with minimal stops. Data has been collected and analyzed in order to implement the best signal timing plan. As our City grows, traffic signals city wide will continue to be evaluated for needed timing adjustments annually.
