Project

Orange County’s population is expected to increase 13 percent by 2035, and that means more drivers on our roadways. To ease growing traffic demands, OCTA, the California Department of Transportation (Caltrans), the County of Orange and all 34 cities are working together to coordinate traffic lights across the county. 

Traffic signal synchronization allows a series of lights to turn green in advance of arriving traffic based on synchronized timers set to current traffic conditions and congestion levels.

OCTA improves traffic flow by coordinating traffic lights across city boundaries. Most signal timing projects result in a 5 to 15 percent improvement in travel time and speed, reducing travel times, stops and delays.
