Abstract: As the passenger flow is increasing, subway station facilities have shown issues incompatible with such a growth. The article sets the research target on Beijing Subway Line 1, selects typical stations and key station facilities as main objectives, investigates the practical passenger passing capacity and passenger distribution rules, collects large amount of first-hand data of station facility’s passenger passing capacity by field study, then compares them with subway design protocols to identify the issue of insufficient capacity of some subway station facilities faced with the passenger flow of today. Based on the research results of domestic and foreign experts, the article uses fitting induction to draw the relation curve of speed and density of the passenger flow at the loading areas and upward stairs of Beijing Subway Line 1, and produces the suitable mathematic model by regression. Lastly, the article offers suggestions on these issues so as to enhance the passing capacity and service quality of the subway stations.
