![]() ![]() If a vehicle does not have a transponder, or if a transponder is not detected at the toll plaza, a violation enforcement system triggers cameras that capture photos of the vehicle and its license plate for processing. The RFID transponder in each vehicle is associated with a prepaid debit account each time the vehicle passes underneath a toll collection site, the account is debited to pay the toll.Ĭurrently, FasTrak transponders are not compatible with E-ZPass and other ETC systems used in other states because they use a different specification than Title 21. FasTrak uses RFID technology near 915 MHz to read data from a transponder placed in a vehicle (usually mounted by Velcro strips to the windshield) moving at speeds that may exceed 70 mph (112 km/h). This specification is known in the transportation industry as "Title 21" after it was added to Title 21 of the California Code of Regulations. Under California law, Caltrans was given the mandate to develop and maintain an open, statewide ETC specification. If the license plate is registered as belonging to a FasTrak user, the account is debited only the toll charge, and no penalty is charged. If the vehicle does not have a transponder, or if a transponder is not detected at the toll plaza, the system classifies it as a violator and cameras (7) take photos of the vehicle and its license plate for processing. Feedback is provided to the driver on an electronic sign (6). As the vehicle passes through the exit light curtain (4), it is electronically classified by the treadle (5) based on the number of axles, and the ETC account is charged the proper amount. The two-antenna configuration (2) reads a transponder (3) mounted on the vehicle's windshield. As the vehicle enters the toll lane, sensors (1) detect the vehicle. Operations and functionality Technology ĭiagram of FasTrak toll collections system. The state continues to delegate the responsibility of selling and maintaining FasTrak accounts to the different toll agencies. Three years later, Transportation Corridor Agencies opened the Foothill Toll Road in Orange County, implementing the statewide ETC system for the first time, and naming it FasTrak. Concerned that they would each introduce different, incompatible ETC systems, the California State Legislature passed Senate Bill 1523 in 1990, requiring the California Department of Transportation (Caltrans) to develop a statewide specification that all these toll agencies were required to meet. Under California's government structure, the state's toll facilities are operated by various agencies and special-purpose districts. Department of Transportation's Intelligent Transportation Systems initiative. Its use of technology to improve transit is in line with the U.S. ![]() The system is used statewide on all of the toll roads, toll bridges, and high-occupancy toll lanes along the California Freeway and Expressway System.Īs with other ETC systems, FasTrak is designed to eliminate the need for cars to stop to pay at toll booths, thus decreasing the traffic congestion traditionally associated with toll roads. FasTrak is the electronic toll collection (ETC) system used in the state of California in the United States.
