​The City’s Signs, Signals crew is responsible for a diverse number of functions that help residents and visitors navigate the City safely.

Signals

The City of Ann Arbor currently maintains more than 200 traffic signals, flashing beacons, illuminated guidance signs and pedestrian crossings. This includes construction, modernization, yearly preventative maintenance and repairs. Traffic signals are connected with fiber optic lines and networked for advanced real-time traffic control. This fiber optic system is also installed and maintained by our signs and signals crew. Adaptive traffic control and signal timing is deployed in many of the areas of the city, and the system is growing.

Signs
