511 Contra Costa is a comprehensive Transportation Demand Management (TDM) program that promotes alternatives to the single occupant vehicle. We encourages the utilization of alternative modes of transportation that eliminate traffic congestion and improve air quality by maximizing the use of our entire transportation network. Commute options include carpooling, vanpooling, telecommuting, biking, public transit, and walking.

511 Contra Costa provides trip planning services for commuters and residents of Contra Costa who need help planning bike routes, managing public transit options, or finding the best rideshare program.  511 Contra Costa provides comprehensive transit maps ( “ Trip Planner”) to find your away around the various public transportation agencies throughout the County and sub-region. Whether you’re a cyclist, a commuter, a business owner, or a senior, 511 Contra Costa has you covered.

511 Contra Costa is sponsored by all twenty jurisdictions in Contra Costa County in California through four regional transportation planning committees that include SWAT (Southwest county), TRANSPAC (Central county), TRANSPLAN (East County), and WCCTAC (West county).  Funding for 511 Contra Costa programs and projects is provided primarily by the Bay Area Air Quality Management District’s Transportation Fund for Clean Air, as well as the local half-cent sales tax (known as “Measure J”) approved by voters in in 2004 and administered by the Contra Costa Transportation Authority. A portion of our Employer Outreach services and programs are funded by the Metropolitan Transportation Commission’s Congestion Mitigation Air Quality funds.


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.

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


In 1994 the municipalities and school districts in Lamorinda collaborated together to establish a school bus program for the purpose of traffic mitigation.  The majority of our funds come from Measure J, a 1/2 cent sales tax in Contra Costa County distributed by the Contra Costa Transportation Authority. Today, we operate twenty-one buses serving 1500 students in the Lafayette, Moraga, Orinda Union and Acalanes Union High School Districts.  During the 2012-13 school year, we successfully eliminated 630,180 vehicle trips.

The school bus program is governed by a Joint Powers Authority (JPA) called the Lamorinda School Bus Transportation Agency (LSBTA).  The LSBTA is comprised of elected officials from each of the cities and school districts and is staffed by Program Manager, Juliet Hansen and Administrative Aide, Sue Graves.  The LSBTA generally meets every other month and meetings are open to the public.  Please contact us for more information.
