This paper studies and presents a pattern for an autonomous traffic information system based on Ad Hoc. In this pattern, the traffic information about travelling time of road section and average travelling speed is collected automatically by moving vehicles in the road net, with no need for fixed facilities for traffic information collection and publication. With the use of the vehicle flow in the road net and the change of Ad Hoc overlapping, the collected traffic information is transmitted, received and integrated through inter-vehicle communication and thus real-time traffic information of the whole road net is formed. Besides, this paper also studies and builds the models of automatic collecting, transmitting and integrating, based on Ad Hoc, of traffic information, and the model of automatic updating of road net traffic information.
