Bus priority system consists of the bus-mounted terminal, roadside positioning and receiving device, signal controller and system platform. When the bus mounted with terminal approaches the intersection in front, the roadside positioning and receiving device reports to the signal controller the current location, speed and punctuality of the bus so that the signal controller may shorten the red light duration or extend the green light duration according to conditions of the on-site traffic and the bus and transmits the message to the prior bus. The bus-mounted terminal will immediately display the message on the terminal screen to help the bus driver make decision and adjust the bus driving status to further realize priority pass of the bus.
