Traffic Congestion Warning Model Based on GIS \ GPS \ GPRS \ RFID Technology

To get the road network in the vehicle's location, speed, direction and a series of information, it innovative RFID-based dynamic access, GPRS (General Packet Radio Service) two-way communications. GPS real-time positioning and GIS path tracking system of the dynamic traffic conditions can be received from information flow, data flow, timely mutual transmission and accurate identification of different vehicles. Thus, through a summary of the above information and combining GIS geographic information system, we can obtain city status in real-time traffic information. It used BP-GM hybrid model to predict traffic way and changed previous single model for efficient and accurate prediction of future time. In order to achieve travel warning and traffic congestion route, quantitative research results and timely feedbacks were used for coming period of road network conditions to prevent the occurrence of massive congestion.
