With the expansion of the city, the number of subway lines has increased, and the subway stations have become more and more crowded. Whether it is possible to transfer quickly and conveniently has become a concern of subway passengers. Especially in big cities, for the convenience of residents' travel, there are many transfer stations between subway lines, and the transfer layout and connection method between subway stations affect the transfer efficiency of passengers. Jiedaokou Station of Wuhan Metro Line 2 is located in the center of Wuhan and is one of the busiest transfer stations in Wuhan. AnyLogic builds a simulation model of passenger entrances and exits and transfers, and observes whether the design of subway station halls is reasonable from the perspective of regional density, regional density, average passenger flow speed and time distribution of entrances and exits. Then, according to the location of congestion and the degree of congestion, it will be designed, modified, optimized and upgraded. After the analysis, a comparison of various schemes and a new round of simulation analysis are carried out. On the basis of summarizing the analysis results of each strategy, the design optimization strategy of the subway station hall is comprehensively proposed. Finally, the feasibility of the optimization strategy is proved again through simulation experiments. This optimization can enable passengers to walk faster in the station and reduce the occurrence of problems such as stagnation and congestion. This paper aims to provide a certain degree of guidance for the design of subway station halls in the future by using AnyLogic simulation method.
