Abstract: With the gradual deepening of urbanization process and the continuous expansion of urban population, the phenomenon of super-large scale passenger flow has appeared in some urban rail transit stations, requiring proactive response from relevant departments to prevent safety risks in advance. Taking the large passenger flow problem of Jiuting station of Shanghai Rail Transit Line 9 as an example, through research on development around the station and analysis of current passenger flow, optimization ideas and opinions from the aspects of passenger flow organization, flow line design and planning adaptation are put forward, for the stations with similar situation in the future. Countermeasures for stations with super large passenger flow are proposed as well, such as optimizing the passenger flow organization, designing the flow line, and promoting the redundancy and traffic matching requirements for the waiting space in the station, so as to meet the needs of the future development of the city.
