The invention relates to a novel traffic information system and particularly relates to a distributed traffic information acquisition and processing system which is based on vehicle equipment and road side facilities and which is integrated through short range wireless communication. A vehicle with corresponding equipment stores passing paths and related traffic information, and when entering a range of short range wireless communication with the road side facilities, the vehicle establishes communication connection. Position and mutual communication time information of a road side facility can be labeled by the road side facility and can be signed and sent to a travelling vehicle as authentication, and authorized data information can be verified and confirmed by other road side facilities. By means of continuous authentication by the road side facilities, the vehicle can be tracked in a traffic network. The system provided by the invention is distributed, and the vehicle has own vehicle calculation and storage functions. A driver can control corresponding equipment, and delete related information in order to protect privacy. The novel traffic information system can widely apply generated and spread information to aspects of traffic management, control and plan, and the like.
