摘要
为对地铁站内行人楼梯进行规划、设计和管理，对上海地铁站内行人楼梯的交通特性进行分析．通过现场观测和摄像调查获取大量数据，利用统计学的方法分析性别、年龄以及信息对楼梯速度的影响规律；根据行人速度随密度变化的大致规律，对给定密度下的行人速度或者流量数据进行合并处理；适当加密变化敏感区域的数据，并利用这些统计数据建立上下楼梯行人的流量一行人密度一速度曲线关系．结果表明性别对行人速度没有显著影响，而年龄和信息对行人速度具有显著影响；从流量一行人密度一速度曲线看，行人在坡度为26°的楼梯的上下楼梯通行能力没有差别，约为88人／（m·min），对应的行人所占面积为0．20～0．22m^2／人．该结果可用于楼梯设施的规划和设计以及行人微观疏散仿真．
In order to plan, design and manage the underground station stairs, the stair traffic characteristics of underground stations in Shanghai are analyzed. The analysis data came through scene surveys and video record investigations. The stair speed rule considering the factors of sex, age, and the information guide is analyzed by statistics methods. According to the change rule of the density with speed, the speed or volume data at the certain density are combined. The relationship between volume, density and speed is obtained through suitably enhancing the density of the data in sensitive regions. The result shows that sex has little impact on pedestrian walk speed, but age and information have significant impact on pedestrian walk speed. From the curve of volume-density-speed, the capacities of up or clown stair at gradient of 26 degree do not have the difference. The volume is 88 person/（ m·min） with the corresponding pedestrian space of 0.20 - 0.22 m^2/person. The result can be applied in planning and designing the stairs and the simulation of the microscopic pedestrian dispersal.
