摘要
准确测量乘客走行速度是评价和优化地铁换乘站各处设施服务水平的重要依据,从统计角度对乘客在不同换乘设施区域走行速度进行研究.分析了影响走行速度的因素,设计乘客步速规律的抽样调查方法并对北京海淀黄庄站不同设施的行人走行速度进行了抽样调查.通过对调查数据的分析,得出了乘客步速在瓶颈处近似服从平方根正态分布,下行楼梯处近似服从对数正态分布.对各处设施内乘客走行速度进行比较,得出不同设施乘客步速的换算系数.
Investigation of the subway passengers＇ average walking speed is the primary work to improve the service level of facilities and to optimize the allocations of various equipments in transfer stations.This research focuses on the passengers＇ average walking speed for transfer from the statistical viewpoint.Firstly,a sampling method is designed based on the analysis of factors affecting the walking speed of the passengers inside the Haidian Huangzhuang Station along the Line No.10 of the Beijing subway.It is proved by the analysis of the data collected in the transfer passage from Line No.10 to Line No.4 at this station that the probability of the walking speed of the passengers in the bottleneck area and downstairs follows respectively the Sqrt-normal distribution and the Log-normal distribution.Its expected value and standard deviation are affected remarkably by the level of congestion.The conversion factors are obtained based on the comparison of different walking speeds in different areas with different types of equipments for transfer.
