Traffic Signals Getting Smarter In Contra Costa County

From Contra Costa Transportation Authority:

Danville – Traffic signals across Contra Costa County are getting smarter.

At a groundbreaking event in Danville on Wednesday, the Contra Costa Transportation Authority (CCTA) marked the advancement of its Countywide Smart Signals project, a countywide effort to modernize approximately 365 intersections and give local agencies better real-time tools to improve safety, reduce unnecessary stops, and help traffic move more smoothly on some of the county’s most important corridors.

The project spans all 19 cities and towns, along with unincorporated Contra Costa County, and focuses on major Routes of Regional Significance where upgraded equipment can strengthen coordination and improve day-to-day traffic operations across jurisdictions.

“The Countywide Smart Signals project is about bringing our traffic signal system up to a modern standard and giving our cities and towns better tools to keep people moving safely and efficiently,” said Tim Haile, Executive Director of CCTA. “These upgrades will help intersections work better together, support safer crossings for people walking and biking, and create the connected foundation we need for better traffic management over time.”

Upgrades to traffic signals could include signal synchronization, vehicle, pedestrian, and bicycle detection, emergency vehicle preemption, transit signal priority, high-speed network connections, remote-view sensors, and battery backup systems, depending on local jurisdiction needs. Initial upgrades will begin in communities such as Danville and Concord, with additional countywide work to follow.

“This is exactly the kind of countywide investment that delivers local value,” said Candace Andersen, Supervisor, District 2, Contra Costa County. “For residents, it means smarter coordination, safer intersections, and better support for emergency response and transit. For our local jurisdictions, it means modern tools and stronger connections along the corridors that matter most.”

“We are proud to host this groundbreaking in Danville and help launch an effort that will benefit communities across Contra Costa County,” said Newell Arnerich, Mayor of Danville. “Danville residents experience every day how important signal timing and traffic operations are to safety and quality of life. Projects like Countywide Smart Signals will help our communities manage traffic more effectively while improving conditions for drivers, pedestrians, bicyclists, and first responders.”

“Modern, connected transportation infrastructure is essential to keeping our communities safe and moving. I’m proud to have secured more than $7 million in federal funds to ensure our community has cutting-edge technology to reduce commutes and ensure safety. Contra Costa is leading the nation in investments like Countywide Smart Signals to help improve mobility, reduce delay, and strengthen the transportation networks commuters rely on every day,” said Congressman Mark DeSaulnier, who represents California’s 10th Congressional District.

CCTA says the project is designed to deliver three core benefits: safer travel, smoother trips, and better tools for cities and towns. Over time, the connected system is intended to support a broader countywide view of traffic conditions that can help agencies coordinate during major events and emergency situations. The project is funded at a total of $30.8 million through Measure J, local city contributions, as well as federal and state contributions.
