For the planning and configuration of escalator at metro station, the characteristics and the process of passengers who use escalator are surveyed; the passing behavior of passengers under different congestion and the factors that influence the capacity of escalators are analyzed. A computation model of the capacity of escalators is built based on the physical and operational characteristics of escalator, and two kinds of passing behavior are assumed; one is all the passengers standing still on the escalator, the other is half passengers standing and half passengers walking, and the passenger distribution coefficients on escalator under the two conditions are also assumed. The passenger flow on escalators of Shanghai metro stations during the rush hour is surveyed, and the observed capacity of passenger flow is got by using statistical method, and then the observed data is compared with the data that are provided by the manufacturers. The result shows that the capacity of escalator provided by the manufacturer and the metro des-gin code are greater than the observed data. Thus the recommended capacity of escalator with width of 1 m and the operating speed of 0.5 m/s is 5 200 persons/(h · m).%为规划和配置轨道交通站的自动扶梯,对轨道交通站内乘客使用自动扶梯的方式和过程进行观测,分析乘客在不同拥挤情况下通过自动扶梯的行为以及影响自动扶梯通行能力的因素；基于自动扶梯的物理和工作特性,假定乘客站立、一半站立和一半行走两种通过行为,以及乘客在自动扶梯上的分布系数,构建自动扶梯通行能力计算模型.在上海地铁站内,调查高峰期自动扶梯的流量,运用统计方法得到实际观测的自动扶梯通行能力,并将其与厂家提供的通行能力数据进行比较.结果表明,厂家和规范数据稍偏大.推荐设计速度为0.5 m/s,宽为1 m的自动扶梯的通行能力为5 200人/(h·m).
