Abstract: Aiming at the usual traffic control measures in Chongqing city, this paper uses VC to design and develop a suit of traffic simulation system which can simulate some traffic control measures such as the opening or closing of road, direction of road, turning rule at crossing and so on, the effect of these measures to the state of road expediting can be analyzed. It introduces some problems on the system such as demand analysis, whole design, construction of message platform, road and crossing design, detection and disposal on vehicle collision, algorithm of way decision-making when vehicle is at crossing, estimating index algorithm for the state of road expediting and so on.

Key words: traffic congestion, traffic simulation, control
