城轨交通换乘站结点换乘设施行人拥堵分析方法

Pedestrian Congestion Analysis Method for Transfer Facilities in Urban Metro Transit Transfer Stations

摘要:

以城市轨道交通换乘站内的“十”形结点换乘设施为研究对象，根据车门至站台梯组的走行距离确定了换乘客流到达时间分布，在考虑设施断面上下游的流密速基本关系及梯前区域、换乘平台、楼梯客流的相互影响关系的基础上，利用分时段客流迭代构建了结点换乘设施行人拥堵分析方法。算例表明，该方法能够在各车门下车换乘人数和站台行人设施布置方案已知的情况下快速分析多向客流的换乘客流量不同组合下“十”形结点换乘设施的行人拥堵情况。

Abstract:

Taking the crisscross node transfer facility in the urban metro transit transfer station as the research object, passenger arrival time distribution was determined by the travel distance from the door to the stairs, and then the passenger flow congestion analysis method of the node transfer facility was constructed by using the passenger flow iteration according to the basic relationship of flow between the upstream and downstream of the section of the facility and passenger flow interrelationship between the area in front of stairs, transfer platform, and stairs. Case studies show that the proposed method can quickly analyze the pedestrian congestion of the crisscross node transfer facilities with different combinations of multi-directional passenger flow when the information about the passenger flows and the pedestrian facilities layout are given.
