Comparison and Selection of Pedestrian Simulation Schemes for Reconstruction of Transfer Channel at Zhichun Road Station of Beijing Metro

As the most critical facility of rail transit transfer station, the carrying capacity and efficiency of transfer channel greatly affect the operation efficiency and safety of transfer station. Different from the entrance and exit channels of the station, on the one hand, the transfer channel is impacted by the pulse large passenger flow with the departure interval as the cycle, and the load is large; on the other hand, due to the relatively narrow passenger circulation space, it is impossible to take operation and management measures such as flow restriction. Once serious congestion occurs, it is very easy to cause safety accidents. Due to the uncoordinated line network planning and inaccurate passenger flow prediction, the capacity of transfer channels in some transfer stations at peak hours is seriously insufficient, so they have to be rebuilt at a great cost. In the past, the comparison and selection of channel reconstruction schemes often used static calculation and qualitative analysis, which was lack of comprehensiveness. Based on the reconstruction project of transfer channel of Zhichun Road Station of Beijing Metro, this paper uses computer pedestrian simulation tools to establish three-dimensional simulation environments of different schemes, evaluates the traffic efficiency of different schemes, and recommends the better scheme in this paper in combination with the difficulty of project implementation.
