Highway Traffic Intelligent Monitoring System Simulation

Great developments have been gotten in traffic research by simulation in our country these years and there is great practical significance in the study of freeway traffic control and management by simulation.In this article, the author establishes a near-microcosmic simulation system through the principle of fuzzy control, which based on the research of the rule of traffic float data of freeway toll station.In the system design, the author, firstly, uses the method, which combines lane control and main artery control, to make synthetic control on whole trip traffic freeway and optimize its result. Secondly, he establishes a rule table of vehicles' behaviors based on analyzing them. The table can simplify the model of vehicle's following and lane changing so that it will shorten the time of simulation. And thirdly, by using the cache technology of level-two time cell, the author solves the conflict, which arises from the limited memory and the masses of cache that is needed to get the better precision in simulation.
