Rail transit offers advantages such as speed,punctuality,efficiency,and safety,which is of great significance for daily urban travel.The vigorous development of rail transit can effectively address challenges like travel difficulties and traffic congestion.By analyzing passenger flow characteristics and spatiotemporal distribution in depth,the operational efficiency of the rail transit system can be significantly improved.This paper takes Fuzhou Metro Line 1 and Line 2 as examples to analyze the passenger flow volume,distribution,and spatiotemporal characteristics at rail transit stations,exploring the regularities and differences in passenger flow characteristics at these stations.Suggestions and measures are proposed for the optimization and management of passenger flow at rail transit stations,with the aim of providing references and insights for the sustainable development of urban rail transit systems.
