As transportation professionals, we're often faced with the challenge of providing additional roadway capacity to reduce traffic delays without increasing the roadway footprint to minimize construction and environmental costs. One way we seek to do this is improving the efficiency of traffic signals to ensure more effective use of existing roadway capacities for vehicles. Signal coordination is a common signal timing strategy utilized in the U.S. to improve roadway operations for vehicles primarily moving long distances. When you've had the good fortune of hitting several green lights in a row as a driver, you've benefited from signal coordination. Signal coordination typically uses a common cycle length and synchronizes multiple intersections with the goal of reducing number of stops and delay for through traffic, as shown here with ideal spacing and uniform intersections. |
