Abstract: Survey and determination of the passengers’ walking time in subway passages is the basic work to realize train coordination between lines and to reduce the passengers’ waiting time in transferring.The paper focouses on the passengers’ walking time on transfer pedestrians from the statistical point of view. First, sampling method is designed based on the analysis of factors affecting walking time and five transfer stations along Line No.5 of Beijing subway is selected to conduct the sampling survey following the method. Then, it is shown by analyzing the data collected in the transfer passage from Line No.5 to Line No.1 at Dongdan station, that the probabilities of walking time of passengers follow Log-normal distribution and its expected value and standard deviation are affected remarkably by crowding. Next, equivalent distance of transferring is conceived considering the real distance of passage and different affections of facilities equipped along. Finally, regression analysis of data from 10 transferring passages shows that the expected value of passenger walking time is quadric to the equivalent distance of passage.

摘要： 对地铁换乘走行时间的准确查定是研究线路间列车合理衔接、减少换乘等待时间的前提，本文从统计的角度对地铁换乘通道乘客走行时间规律进行了研究。首先分析了影响走行时间的因素，设计了推断乘客走行时间规律的抽样试验方法。采用该方法，选择北京地铁5号线的5个换乘站进行了抽样调查。通过对东单站5号线换乘1号线通道样本的分析，得出乘客走行时间近似服从对数正态分布、拥挤对分布均值和方差影响显著的结论。接下来分析了分布函数参数的影响因素，在综合考虑通道实际长度和通道内设施影响程度后提出换算长度概念。通过对10个换乘通道的回归分析，表明走行时间均值与通道换算长度在一定范围内二次相关。
