Research on Traffic Information Acquisition and Traffic Evaluation Schemes for Urban Roads in Mountainous Area

Advanced traffic management systems can effectively improve effective availability and traffic flow of urban modem traffic and reduce traffic congestion and occurrence rate of traffic accidents of roads as well as travel delays due to traffic congestion and accidents, etc. The urban intelligent traffic management system improves the work efficiency of the traffic management system via application of high-tech and high -level techniques so as to achieve the purpose of changing the mess of urban traffic. This paper conducts analysis and research aiming at road traffic information acquisition sub- system of Chongqing urban intelligent traffic management system and the relevant techniques, and proposes principle and scheme of road traffic information acquisition and data processing in Chongqing on the basis of research on urban intelligent traffic management system and in combination with current situations of traffic and level of traffic intelligentization in Chongqing.
