Our Member Agencies:

Los Angeles County Metropolitan Transportation Authority (METRO)

Los Angeles County Metropolitan Transportation Authority (Metro) is unique among the nation’s transportation agencies. It serves as transportation planner and coordinator, designer, builder and operator for one of the country’s largest, most populous counties. More than 9.6 million people – nearly one-third of California’s residents – live, work, and play within its 1,433-square-mile service area. The Los Angeles County Metropolitan Transportation Authority operates the third-largest public transportation system in the United States by ridership with a 1,433 mi² (3,711 km²) operating area and 2,000 peak hour buses on the street any given business day. Metro also designed, built and now operates 98.5 miles (158.5 km) of urban rail service. The authority has 9,892 employees, making it one of the region's largest employers.

Orange County Transportation Authority (OCTA)

Since its formation in 1991, the Orange County Transportation Authority (OCTA) has kept residents and commuters moving throughout the 34 cities and unincorporated areas of Orange County. OCTA’s responsibilities, programs and services impact every aspect of transportation within the state’s third largest county. OCTA keeps people moving by reducing freeway congestion, improving safety and efficiency on our local roads, providing bus service and regional multimodal connections, helping people find ways to leave their cars home, and providing safe, convenient transportation to those with special needs. OCTA began in 1991 with the consolidation of seven separate transportation agencies. By increasing efficiency and eliminating duplicate functions, we save county taxpayers millions of dollars. The OCTA Board of Directors is comprised of 18 individuals that represent Orange County. Specifically, seventeen Board members govern OCTA with the Caltrans District Director serving as the 18th member in an ex-officio capacity.

Riverside County Transportation Commission (RCTC)

Since 1976, when RCTC was created by the state legislature, local voices have had an important and critical role in deciding our transportation future. In 1988, RCTC proposed a half-cent sales tax for transportation, Measure A. When 78.9% of voters approved the 20-year plan, RCTC became the agency charged with making sure the mobility improvements voters wanted became a reality. In 2002, voters approved an extension of Measure A until 2039. Today RCTC plans and implements transportation and transit improvements, assists local governments with money for local streets and roads, helps smooth the way for commuters and goods movement, and ensures that everyone has access to transportation. RCTC is governed by a 34 member Commission that includes a mayor or council member from each of Riverside County’s cities, all five members of the Board of Supervisors, and a non-voting appointee of the Governor.

San Bernardino County Transportation Authority (SBCTA)

San Bernardino County Transportation Authority, known as SBCTA, is the council of governments and transportation planning agency for San Bernardino County. SBCTA is responsible for cooperative regional planning and furthering an efficient multi-modal transportation system countywide. SBCTA serves the 1.9 million residents of San Bernardino County. As the County Transportation Commission, SBCTA supports freeway construction projects, regional and local road improvements, train and bus transportation, railroad crossings, call boxes, ridesharing, congestion management efforts and long-term planning studies. SBCTA administers Measure I, the half-cent transportation sales tax approved by county voters in 1989.

Ventura County Transportation Commission (VCTC)

The Ventura County Transportation Commission (VCTC), is a regional transportation planning agency committed to keeping Ventura County moving! If you drive, take transit, bike or walk in Ventura County, chances are, the VCTC has helped you do it. By working in close partnership with each of the cities and the County, the VCTC is ever mindful of maintaining the character of Ventura County while prioritizing transportation investments. The commission was created by state legislation in 1988 and began operation in 1989, when it assumed the transportation responsibilities of the Ventura County Association of Governments. The VCTC is one of five member agencies which make up the Southern California Regional Rail Authority (Metrolink).
