The invention relates to a signal lamp dispatching system comprising a server, vehicle-borne positioning devices, and intelligent signal lamps. The server is connected with the vehicle-borne positioning devices through communication. Each vehicle-borne positioning device includes a controller, a communication module and a positioning device, wherein the positioning device is a high-precision positioning device which can position a vehicle to a lane. Each intelligent signal lamp includes a communication module and a signal lamp controller which can receive a control instruction sent by the server and control the running of the signal lamp according to the received instruction. The server acquires the accurate real-time positions of a large number of on-road vehicles so as to position the vehicles to lanes. The server can calculate the congestion index of a lane, predict the congestion index of the lane in a future period of time, and carry out signal lamp dispatching according to the congestion index of the lane and signal lamp dispatching rules.
