Department of Public Works
Traffic Signal Shop
The Traffic Signal shop maintains 250 signalized intersections in a 600 sq. mi. area surrounding, but not including Baltimore City. Baltimore County has 11 arterial signal systems coordinating 100 intersections. The signal systems are equipped with telephone interconnects and modems. The interconnects allow maintenance staff to graphically view the operation of each intersection to determine if it is operating properly. Examples of arterial systems are York Rd., Joppa Rd. and Merritt Blvd. The remainder of the signals operate independently.
The duties of this division are:
- Constructs new signals and modify existing signals when functional changes are required.
- Repairs signal equipment damaged by accidents, construction and natural disasters.
- Test repair and program traffic signal control electronic equipment.
- Maintains all traffic signals, flashers, and signal systems along the County highway system and some of those on the State highway system in Baltimore County.
- Installs and monitors signal and system timing.
- Maintains level-of-service (LOS) rating for signalized intersections.
- Maintains signal timing and maintenance records, and inquiries regarding accidents and incidents.
