As an important node in the urban subway transportation network, the subway interchange station often has the characteristics of complicated passenger flow lines and numerous customer service equipment. As the only subway interchange station in Changsha till this moment , Wuyi Square Metro Transfer Station is located in the urban central business district, which not only becomes the “facade” of urban traffic, but also its transfer efficiency is considered to be an important factor in the development of urban green transportation .However, in recent years, with the increase of residents' travel and the continuous popularization and development of rail transit such as subways, the efficiency of passenger flow organization at Wuyi Square Station has been difficult to meet the actual passenger demands. Based on the survey results of the existing facilities layout and passenger flow situation of Wuyi Square interchange station in Changsha City, this paper establishes an evaluation system, analyzes the causes of conflicts in passenger flow organization according to the theory of intensive crowd management, further proposes specific optimization schemes, and then uses Anylogic software. The optimization schemes were simulated before and after the optimization. Finally, the comprehensive evaluation values before and after the optimization were 0.9318 and 0.9693 based on the entropy method, which verified the optimization effect. The specific use method of Anylogic pedestrian simulation software proposed in this paper for the optimization of passenger flow organization of Wuyi Square transfer station, as well as the specific optimization schemes have certain reference significance for the passenger flow organization work of the station. Key words: Passenger flow organization optimization Anylogic simulation Entropy method Wuyi Square transfer station
