Description

  The present invention relates to a vehicle allocation system used in, for example, an AVM (Automatic Vehicle Monitoring) system for taxi allocation using a commercial radio.

  With the development of wireless communication technology, the positioning technology using radio waves has been greatly developed. Today, the positioning system using GPS (Global Positioning System), the accuracy of the GPS receiver alone in the world is about 10m error. Now you can get location information. This GPS technology is mainly used for car navigation, navigation of ships and aircraft, surveying, and the like.

  In addition, with recent development of wireless mobile communication systems, it is possible to easily perform mobile data communication for a wide area. Fusion of these positioning technologies and wireless mobile communication systems has put mobile location management systems and text transmission systems into practical use, with the aim of improving the efficiency of delivery of home delivery vehicles and taxis through public and commercial radios. It's being used.

Therefore, a radio vehicle allocation system has been proposed in which a GPS receiver is provided in the vehicle, and the acquired position information is transmitted to the vehicle allocation center when responding to the vehicle allocation inquiry, so that the vehicle allocation center can grasp the position of the response vehicle. (For example, see Patent Document 1).
