摘要
介绍了由BPR函数拓展而得到的轨道交通站厅内行人流条件下的路阻函数形式,并对其影响因素进行分析。在此基础上,对南京地铁新街口站自动扶梯和人行楼梯上的行人流进行实地调查,用实测数据拟合确定了南京城市轨道交通行人通道的路阻函数模型。研究结果表明,经由实测数据标定得到的路阻函数模型拟合效果较好,可以为轨道交通车站内设施布设等运营决策提供理论参考。
In order to improve the efficiency of urban rail transit passenger organization,evaluate the reasonable degree of facility layout at the stations, and further enhance the overall service level of rail transit system,this paper introduces the impedance function of pedestrian flow at urban rail transit stations,which is derived from the BPR function of the U.S. Federal Highway Administration（FHWA）,analyzes the impact factors and defines the impedance function model of passenger corridor at urban rail transit stations,by using the measured data of pedestrian flow on escalators and stairs at Nanjing metro station.The results show that the fitting of the impedance function model is acceptable and can provide a theoretical reference of operational decision-making for the station’s layout design.
