Study on Overpass Plan Based on Micro Simulation Model

With microscopic traffic simulation model adopted to analyze overpass plan operation, the quantitative index such as travel time,velocity,delay and queue length can be obtained, providing a method to study overpass plan from the perspective of traffic operation. The article discussed the procedure of analyzing overpass plan by using microscopic traffic simulation model,and taking the simulation analysis of an overpass plan of Nanning City,it verified the feasibility of using this simulation model to analyze overpass plan traffic operation.
