Countywide Signal Priority (CSP) Program
The Countywide Signal Priority (CSP) Program is the largest implementation of multi-jurisdictional signal priority in the nation. It has established new transit signal priority standards and the approach has been broadly adopted in Los Angeles County. Currently, nearly a third of the 89 jurisdictions in the County have or will shortly have priority-equipped intersections, with about 250 intersections already equipped to grant signal priority to buses. The Program is closely coordinated with Metro and municipal transit agencies, including Culver City Bus, Foothill Transit, Gardena Transit, Santa Monica Big Blue Bus, and Torrance Transit.
In 2017, Metro evaluated the next generation of bus signal priority (BSP) technologies as part of the Metro NextGen Bus Plan, which looked at BSP technologies deployed nationwide and assessed the existing BSP system. The study provided the program with different types of emerging BSP technologies to consider for the future of the CSP program. With the aim of doubling the number of equipped intersections, the program seeks to expand its footprint by commissioning new BSP systems along some corridors and modernizing existing systems for others. The CSP program is determined to continue improving transit service and reducing congestion in the region.
