context_page_description: AC Transit is an Oakland-based public transit agency serving the western portions of Alameda and Contra Costa counties in the East Bay of the San Francisco Bay Area. AC Transit also operates "Transbay" routes across San Francisco Bay to San Francisco and selected areas in San Mateo and Santa Clara counties. AC Transit is constituted as a special district under California law. It is governed by seven elected members. It is not a part of or under the control of Alameda or Contra Costa counties or any local jurisdictions.
  Buses operate out of four operating divisions: Emeryville, East Oakland, Hayward, and Richmond. The Operations Control Center is in Emeryville. The Richmond operating division closed in 2011, but opened again in early 2017 due to a revived economy. The District is the public successor to the privately owned Key System.
context_section_description: A rapid bus line was introduced on San Pablo Avenue on June 30, 2003. Designated as Line 72R (or San Pablo Rapid), it operates from 6 am to 7 pm at 12-minute intervals on weekdays, and 7 am to 7 pm at 15-minute intervals on weekends and holidays. Bus stops are spaced 2/3-mile apart on average, running between Jack London Square (via 20th Street and Broadway) in Oakland and Contra Costa College in San Pablo, and buses receive signal priority at several intersections. Although the line does have scheduled timepoints en route, most buses typically travel along the route as fast (or as slow) as traffic allows.
  On June 24, 2007, the success of line 72R made it a model for another rapid bus line that was introduced. Line 1R (or International Rapid) operated on weekdays between Berkeley Way and Oxford Street in Berkeley and Bay Fair BART station in San Leandro, mainly along Telegraph Avenue, International Boulevard, and East 14th Street. Weekend and holiday service operated between Downtown Oakland and San Leandro only.
  Line 1R was discontinued on June 26, 2016. On August 9th, 2020, the 1R was largely replaced by Tempo, AC Transit's new Bus Rapid Transit (BRT) route. Tempo operates between the Uptown Transit Center and the San Leandro BART station via International Boulevard and East 14th Street. It features 46 brand new platform stations (curbside and center-median) with dedicated bus lanes along the majority of the route. The Telegraph Avenue alignment of the 1R between the Uptown Transit Center and U.C. Berkeley is currently being served by local route 6.
