Analysis of Rail Transit Station Passenger Capacity Based on System Dynamics

Passenger capacity of rail transit station is not only the basis of station design and passenger flow organization, but also an important factor to ensure safety operation of rail transit. This paper analyzes urban rail transit station from the perspective of system, and discusses the coordination and feedback relationships of passenger flow distribution between different facilities. By analyzing the law of the passenger flow, a system dynamics simulation model is established with the system dynamics software, Stella, and the limits of passenger capacity of Beijing Dongdan station is calculated under different conditions. These results provide bases for the management of transit operation.
