Traffic Signals

The Winston-Salem Department of Transportation (WSDOT) installs and maintains all traffic signals within the city in accordance with the Manual on Uniform Traffic Control Devices. Signals are installed based on need as determined by traffic engineering studies. The Director of Transportation approves the installation of all signals. The North Carolina Department of Transportation (NCDOT) must also approve signal installation on a State System street.

Computerized traffic control coordinates the timing and operation of over 300 traffic signals citywide. Drivers can travel from one signal to the next with minimum stops and delays. Metal detectors embedded in the pavement sense vehicles waiting in travel lanes. The signal coordination reduces driver delays, vehicle pollution emissions, and gasoline consumption. Timing plans are evaluated every six months and specific locations are evaluated based on citizen concerns and complaints.

To report nonfunctioning or improperly functioning signals, please call City Link at
