Abstract: In the identification of traffic congestion state, the original data acquisition usually adopted the floating car and road test equipment, which usually had large error and seriously affected the accuracy of various traffic analysis models. An information sharing system of traffic congestion based on TCP/HTTP was proposed, which could effectively integrate two kinds of information resources: the objective information data of the simulated floating car and traffic flow was collected by the TCP protocol; meanwhile, the subjective information data of traffic congestion state was uploaded by the HTTP protocol in real-time. The proposed information sharing system included traffic congestion information sharing collection, floating vehicle information collection simulated by intelligent terminal, traffic flow information collection of intersections, which could realize the function of remote calling schedule of the intelligent terminal. The proposed system can provide the most intuitive decision support for traffic congestion analysis.
