Greensboro Traffic Signal System

Owner: City of Greensboro

Engineering: Kimley-Horn & Associates

Awarded the 2014 Best Project of the Year Award by ITE International Management & Operations/ITS Council, the Greensboro project rehabilitated and expand the City’s computerized traffic signal system—the largest North Carolina signal system design to date. The new network interconnects not only traffic signals, but also City facilities through an innovative partnership between the City’s Transportation and IT Departments. This multi-purpose network encompasses over 450 traffic signals, over 50 closed circuit television cameras, and over 40 City facilities interconnected by more than 120 miles of fiber optic cable.

The project included innovations such as the use of Ethernet DSL modems for the downtown signals to avoid negative aesthetic impacts to historic downtown Greensboro.  As a result of the improved and expanded signal system, the City of Greensboro’s residents now experience fewer delays along their roadways and traffic flow has been improved by 20% on some corridors.
