Research & Design Of Vehicle Supervising System Based On GIS/GPS/GPRS

ITS(intelligent traffic system)is a new technology field that comes into being, as soon as more and more electronic technology ,communication technology and database technology were applied in traffic control. From the viewpoint of system theory, ITS considers four factors: people, road, vehicle and environment, synthetically. It comes up with many solutions in order to reduce the occurrence of traffic-jams and accident. Further more, TTS has become an important tendency of modern traffic engineering.In order to put theory into practice, the author researches many theories and applications of ITS and vehicle supervising system. The research work achieved, during the course of author completing the paper, is discussed in detail as follow.Firstly, this paper discusses the basic theory of ITS and analyzes its development both domestically and overseas.Secondly, vehicle supervising system is a typical application of ITS in traffic control and management. The paper discusses the basic theory, systemic structure and systemic function of the vehicle supervising system. The paper also analyzes the related key technology of this system such as GIS, wireless position technology, wireless communication etc.At last, this paper discusses the designation and implementation of a GIS/GPS/GPRS vehicle supervising system. This system produces a practical measure to resolve the problems in traffic control and management, such as vehicle hijacking, vehicle safe, vehicle management discommodiously. It can offer the following functions: On one hand, users can query both the position and the state of vehicle. On the other hand, the vehicle can send the help signal to the vehicle supervising center while the vehicle encounters traffic accident or the vehicle is hijacked. According to the help signal, users and vehicle supervising center can dispose the accident at time. In addition to these the author draw out a new solution based on software technology to improve the performance of the system. This GIS/GPS/GPRS vehicle supervising system can be applied in TAXI, goods circulation and private vehicle etc. This system also produces a method to enhance the vehicle management and the ability of vehicle safe. The system has experienced practical test and achieved expectant result.
