There are more and more related factors that affect traffic operation.Simply applying conventional theoretical calculations and comparing technical indicators for evaluation is no longer the optimal solution to solve various traffic problems.In this article,the application of traffic simulation results based on the interchange scheme of a certain project has been introduced,the key nodes of interchange design have been optimized.In this paper,the selection of design specification for circular interchanges and the key points of traffic organization design have been proposed,and a scientific and effective method for selecting parameters of traffic simulation models has been put forward.
