An Intelligent Vehicle Traffic Information System Mode and Evaluation

Zhang Qi, Zheng Hao, Zhang Jianping and Peng Hong    

Abstract: The investment of centralized traffic information system is large and data processing is too concentrate, the autonomous traffic information system based on vehicle-to-vehicle communication is mostly limited to information on safe driving, less involved with the research of the whole road network congestion information collection and transmission. This study puts forward an autonomous intelligent vehicle traffic information system mode which is for the whole urban road network and can collect and transmit information by itself. And then, based on the original information and integration processing model, it builds the corresponding self-diffusion transmission model for different roads, different driving direction vehicles and different information integration results. It also creates autonomous generation and dynamic update models of traffic congestion information for the whole road network. The traffic simulation and the evaluation results in a variety of situations show that IVTIS mode and models are reasonable and basically adapted to autonomous collection and quick transmission for traffic congestion information in urban road network.
