Abstract: The bottleneck for the gathering and distributing capacity of urban rail transit station leads to serious passenger traffic congestion and reduces the distribution performance of stations ,which affects the efficiency and safety of passenger travel .Based on the full analysis of the connotation and cause of the gathering and distributing capacity bottle-neck of urban rail transit station ,the bottleneck identification method based on the congestion level is put forward .First-ly ,the cumulative Logistic regression based on a congestion level measurement model is built .Then ,the model is calibra-ted and validated with the survey data .Finally ,by taking Beijing Dongzhimen Rail Transit Station as the study site ,the validity of the model is verified by using Anylogic dynamic simulation .Results show that the model can accurately reflect the bottleneck of the gathering and distributing capacity of urban rail transit station in real time .
