TRAFFIC SIGNAL SYSTEMS FROM CENTRAL TO DISTRIBUTED, NOW INTO THE FUTURE

The focus of this paper is on the operational aspects of traffic signal control systems. In the past, elected officials were not always concerned with the spacing of traffic signals and in many cases allowed land uses to dictate street patterns. As development moved away from the central city, and suburban employment centers were developed, directional flows began to disappear. With new work places in the suburbs, traffic flows on the major roadways were no longer directional. The Traffic Engineer had to develop new timing patterns that provided coordination for traffic in both directions. This now made signal timing much more difficult and Traffic Engineers required more complex traffic signal systems. Centralized systems were the first systems developed to handle the chores of coordinating traffic.
