Abstract: 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.
