OCTA, in partnership with local cities, the County of Orange and Caltrans, continues to expand its Regional Traffic Signal Synchronization Program that improves traffic flow, reduces congestion, and enhances air quality.
Since 2008, the program has synchronized nearly 3,800 intersections across the county, reducing travel times by 13 percent, cutting stops by 28 percent and improving average speeds. These efforts have prevented 1.3 billion pounds of greenhouse gas emissions and saved drivers an estimated $250 million in fuel costs.
“Signal synchronization is about making everyday driving easier for people across Orange County,” said OCTA Chair Doug Chaffee, also Chair of the Orange County Board of Supervisors and Fourth District Supervisor. “By better coordinating traffic lights, drivers can spend less time stopped at red lights, save on gas, and enjoy a smoother trip. It’s a simple, cost-effective improvement that shows how Measure M continues to deliver real benefits to the community.
There are currently 30 active projects underway, representing $78 million in investments and covering an additional 283 miles of roadway. More than three-quarters of these efforts revisit previously completed corridors to ensure signals continue to match evolving traffic patterns.
Funded by Measure M, Orange County’s half-cent sales tax for transportation improvements, the program underscores the value of regional cooperation in making travel safer, more reliable, and more sustainable across the county.
