Countywide Smart Signals
About this Project
Contra Costa Transportation Authority (CCTA) is leading a Smart Signals Project to upgrade traffic signals at over 300 intersections throughout the 19 cities/towns and unincorporated communities within Contra Costa County. This work is focused along major arterials that have been designated as “Routes of Regional Significance.”
What is a Route of Regional Significance?
A roadway that connects two or more subareas of Contra Costa, crosses County boundaries, carries significant through traffic, and/or provides access to a regional highway or transit facility.
Right Time For An Upgrade
Existing traffic signals within Contra Costa are not connected to each other (like with fiber or ethernet), preventing synchronization and coordination between signals. Additionally, most modern signal systems need Signal Control and Prioritization (SCP) technology that can help transit vehicles and alternative modes such as bikes and shuttles, move through intersections safely and efficiently.
By incorporating modern elements into the County’s signal systems, CCTA will optimize traffic flow on its arterials, reduce congestion, and hopefully eliminate spillover of congestion onto the freeways. Efforts performed with this project will also enable CCTA to enhance safety for all modes, monitor traffic conditions in real-time, improve incident management and response times, and prepare Contra Costa for other emerging transportation technologies.
