The invention discloses a method for numerating vehicle overspeed, wherein devices which are applied in the method comprise a central system and a vehicle-mounted terminal, wherein the vehicle-mounted terminal is arranged on a vehicle and can realize data transmission with the central system, the data at least comprises real time GPS running data which is sent from the vehicle-mounted terminal to the central system, and dispatching information which is sent from the central system to the vehicle-mounted terminal, the method comprises the following steps: firstly, a step of setting, presetting the value of speed limit of vehicle running in the central system, storing the presetting, secondly, a step of processing data, receiving GPS data sent by the vehicle-mounted terminal by the central system, judging whether the speed value of the GPS data is bigger than the value of speed limit or not, sending an alarming signal to administrative staff if the speed value of the GPS data is bigger than the value of speed limit, sending the dispatching information to the vehicle-mounted terminal, enabling the vehicle-mounted terminal to process the dispatching information to prompt drivers, setting a recorded overspeed mark field as overspeed when the GPS data is stored, otherwise directly storing the GPS data, thirdly, a step of numerating, searching out the GPS data with an overspeed mark according to input vehicles and time by the central system, and forming an overspeed list, and providing for the administrative staff to examine according to the GPS data.
