Signal systemThe Traffic Signal Engineering staff conducts studies to determine where traffic signals are needed, prepares traffic signal designs, and oversees the operation and optimization of 488 signalized intersections.

The central computerized control system monitors and coordinates the operation of signals enabling operators to optimize traffic flow along major corridors. The system is currently being updated and will be complete in 2014.

The locations of new traffic signals are determined by counting traffic at candidate intersections and applying uniform guidelines, or warrants, developed by the Federal Highway Administration. Volume of traffic, accident history, and intersection spacing are all factors in determining the placement of new traffic signals.
