How It Works - General Information

TRAFFIX is a traffic congestion relief program funded by Measure J, the 1/2 cent sales tax approved by Contra Costa voters in 2004. Its sole purpose is to reduce traffic congestion caused by parents driving their children to and from school through some of the San Ramon Valley's most congested intersections.

TRAFFIX began service in August 2009 with a fleet of new clean-burning buses with state-of-the-art safety features. To encourage parents to stop driving their kids to school, TRAFFIX provides this service at less than half the cost of traditional school bus programs - only $335 for an entire school year. Parents who register early in the Spring and Summer get a bus pass for only $260.

To determine where the program would reduce the most traffic, TRAFFIX conducted comprehensive traffic studies throughout the Valley, and surveyed parents at all San Ramon Valley schools. After careful analysis, TRAFFIX established routes and service for Los Cerros Middle School, Green Valley and Vista Grande Elementary Schools in Danville, and Pine Valley Middle School, Country Club, Neil Armstrong, and Walt Disney Elementary Schools in San Ramon.  

In 2012, TRAFFIX added bus routes and service for Monte Vista High School in Danville and California High School in San Ramon.  In 2014, TRAFFIX added a bus route and service for San Ramon Valley High school in Danville and Coyote Creek Elementary School in San Ramon. Two additional buses were added to the Monte Vista fleet, serving CSA T-1 residents at Alamo Creek and Monterosso in 2014 and 2017.

TRAFFIX is operated jointly by the Town of Danville, City of San Ramon, Contra Costa County, and the San Ramon Valley Unified School District, with funding from Contra Costa County Measure J and County Service Area T-1.
