The Orange County Transportation Authority (OCTA) is the transportation planning commission for Orange County, California in the Los Angeles metropolitan area. OCTA is responsible for funding and implementing transit and capital projects for the transportation system for the travel needs, including freeway improvements, express lane management, bus and rail transit operation, and commuter rail oversight. OCTA was founded in 1991 through the consolidation of seven separate transportation agencies and is governed by a 17-member Board of Directors with the Caltrans District Director serving in a non-voting capacity. The Authority's administrative offices are located in the City of Orange. History OCTA's predecessor agency, the Orange County Transit District, was created in August 1972 by a referendum of county voters. It originally started as Santa Ana Transit, a small transit agency with five bus routes operating in Orange County. Santa Ana Transit later merged with other, smaller agencies throughout the county, eventually leading to the formation of OCTD. The routing system was formed over the course of about 15 years and was held in place until the merge to OCTA. In 1991, OCTA was created under state law, combining the seven separate Orange County agencies that managed transportation planning: Orange County Transportation Commission, Orange County Transit District, Consolidated Transportation Services Agency, Orange County Local Transportation Authority, Orange County Service Authority for Freeway Emergencies, Orange County Congestion Management Agency, and Orange County Service Authority for Abandoned Vehicles. Park-and-ride facilities, public transportation and other transportation related administrative offices merged into one organization. OCTA administers funds from Measure M (also known as OC Go), a half-cent transportation sales tax. Measure M was originally passed in 1990 and renewed in 2006. It has paid for the expansion on most freeways within Orange County, street improvements and repairs, traffic signal synchronization, and increased Metrolink service. In 1995, OCTA suffered tremendously during the Orange County bankruptcy and never fully recovered. The agency lost $202 million in revenue over 17 years due to the bankruptcy. As a result, bus service was reduced. In October 2015, OCTA rebranded its bus services as "OC Bus" and launched the OC Bus 360° plan, which aims to consolidate routes into more frequent service and increase ridership. OCTA also plans to replace 40% of its bus fleet with compressed natural gas-powered vehicles. The change was approved by the OCTA board on February 22, 2016. In January 2022, OCTA debuted battery-electric buses. Bus operations OCTA
