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.”
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.
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.
What is a Route of
Regional Significance?
Benefits of Smart Signals
Safer Roads: Imagine better emergency
response times, easier management of
incidents by first responders and law
enforcement, and reduction of secondary
incidents due to video analytics that can
identify near-miss situations.
Smoother Travel: Synchronized,
responsive signals can reduce idling at
red lights, improve speed management,
decrease travel delays, reduce greenhouse
gas emissions, and increase transit reliability.
Better Traffic Management: Cities and
Caltrans will have access to real-time data
that allows optimization of traffic during
incidents, evacuations, or other major
events. Cities will be able to prioritize transit
and emergency vehicles as needed.
