The City of Columbia maintains more than 270 traffic signal installations.
Coordination of these signals to optimize traffic flow requires a large amount of data regarding traffic volumes during various periods of the day.
To provide flexibility in traffic system control, the City is currently in the process of upgrading the existing traffic signal coordination equipment in the Columbia area. Using federal and state matching funds, Traffic Engineering is currently directing the construction of a new, upgraded signal system in the downtown area. Computerized traffic signal systems will be designed and installed on Harden Street, Harbison Boulevard, Garners Ferry Road, Two Notch Road, Forest Drive and Rosewood Drive.
