A traffic-engineering firm conducted a comprehensive study of major intersections throughout the San Ramon Valley. The intersections were ranked by their congestion during peak morning and afternoon traffic periods related to nearby schools. Parents at all SRVUSD schools were surveyed to measure their willingness to participate in a busing program. The schools were then ranked by how much traffic congestion they caused and how likely their parents were to buy a pass and have their kids ride.
Based on these factors, TRAFFIX selected seven schools for service in the 2009-2010 school year that showed the greatest chance to reduce traffic congestion: Los Cerros and Pine Valley middle schools; Country Club, Green Valley, Walt Disney, Neil Armstrong and Vista Grande elementary schools. In subsequent studies, California and Monte Vista high schools were selected for service in the 2012-13 school year to reduce traffic congestion. Beginning in the 2014-15 school year, Coyote Creek elementary school and San Ramon Valley High School were added to the TRAFFIX fleet service.
