VISSIM simulation evaluation design of city expressway intersection

This paper has operated the traffic survey,collected and analyzed the data,found the congestion of the road and optimized it,alleviated the congestion,evacuated the traffic jams.Taking real intersection as example,this paper records the traffic flow and timing control,analyzes traffic condition.At the last,this study simulates the traffic operation status under the present condition with traffic simulation software VISSIM and improves the signal timing.
