 Traffic Signal Program

Traffic Signals

Green Light

Since 1989, DRCOG's Traffic Operations Program has been working with the Colorado Department of Transportation and local governments to coordinate traffic signals on major roadways in the region. The program reduces traffic congestion and improves air quality. DRCOG was one of the first metropolitan planning organizations (MPO) to conduct such a program, and remains the leader among the very few MPOs throughout the United States involved in traffic signalization efforts.

The Traffic Operations Program efforts are governed by the Traffic Signal System Improvement Program (TSSIP), which has two major components:

  • a capital improvement program (which provides equipment and installs communications links), and
  • a traffic signal timing improvement program (which provides new traffic signal timing and coordination plans).

  • The brochure Why is the Signal Always Red? prepared by DRCOG provides an informative overview of some of the challenges involved in improving traffic signal timing and coordination.
