Abstract: A passenger behavior-oriented smart urban public transport system and its implementation, which includes a field system mounted on a vehicle and a control center controlling the field system. The field system is connected to the control center via a wireless connection means. The control center is for receiving trip instructions from a passenger, generating a bus running route and sending said route to the field system mounted on the bus. The bus will then travel along the route received from the control center. The control center will also send the information of the route to the passenger while the bus is on its way. This invention provides an entirely new type of urban public transport automatic management system, which centers around the response to passenger travel demands, providing bus service at suitable places for passengers to get on and get off through the control center's intelligent scheduling and dispatching of the vehicles in the system.
