ABSTRACT
In response to the great impact of road occupation and the long construction period of urban expressway construction, traffic simulation technology was adopted to simulate the traffic organization scheme. The causes of congestion were analyzed according to the simulation results, and optimization suggestions were put forward to support the feasibility of the traffic organization scheme. First, the VISSIM traffic simulation software was used to build the simulation model of the urban expressway traffic organization scheme; second, traffic simulation was carried out according to the simulation model to analyze the causes of poor service levels on some road sections and put forward optimization suggestions; finally, the traffic organization scheme was optimized according to the optimization suggestions, and the schemes before and after optimization were compared to verify the feasibility of the scheme and provides a guarantee for the efficient operation of traffic during urban expressway construction.
