The Town of Danville is a participating member of the Measure J Traffic Congestion Relief Agency, an independent joint powers authority known as TRAFFIX.

Reduce Traffic Congestion

TRAFFIX is a traffic congestion relief program funded by Measure J, the 1/2 cent sales tax extended 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 is operated jointly by the Town of Danville, City of San Ramon, Contra Costa County, and the San Ramon Valley Unified School District.

San Ramon Valley Schools

TRAFFIX began service in August 2009 with a small fleet of new, clean-burning buses with state-of-the-art safety features. To determine where the program would have the biggest impact on reducing traffic congestion, TRAFFIX conducted comprehensive traffic studies throughout the San Ramon Valley and surveyed parents at all schools within the San Ramon Valley. After extensive evaluation, TRAFFIX service was initially provided at seven schools including Los Cerros Middle School, Green Valley Elementary School and Vista Grande Elementary School in Danville. The program has since been expanded (as funding has allowed) and now includes a total of 23 buses serving approximately 1,700 students at 11 schools throughout the San Ramon Valley. In addition to the aforementioned Danville schools, service is now also provided at San Ramon Valley High School and Monte Vista High School.

2019-20 TRAFFIX PASS Rates

TRAFFIX passes for the 2019-20 school year are now on sale. The current annual regular pass rate is $395. A promotional rate of $355 was offered for Elementary and Middle School riders between April and June 15 2019, and typically offers limited-time specials throughout the year to elementary and middle school families to promote ridership. The rates equate to about $2 per day for the school year and is a more economical and environmentally-friendly alternative to the passenger vehicle trip while helping to reduce congestion and increase safety in and around San Ramon Valley schools.
