近年来，自动扶梯在公共建筑、大型交通枢纽站场中的使用率越来越高; 其载客输送能力直接影响人群的疏散，是自动扶梯设计中的一个重要因素; 但相应的动力学特性难以描述．对于动力学特性难以描述的交通设施来说，实证分析法是一个非常有效且具有可操作性和一定精度的分析方法．因此，通过对广州地铁站上行自动扶梯人流高峰时段的拍摄及相关数据处理，建立了梯级宽度为1 m 的扶梯入口段与扶梯段的行人交通基本特性图．对其分析得知，自动扶梯实际载客能力为8655 人/h，为理论载客能力的90%．

In recent years,the utilization of the escalator in public buildings and large transportation hubs has become more and more frequent and popular. Its capacity is a vital factor in the design of the escalator because it has a direct bearing on the crowd evacuation. However,it is difficult to describe the corresponding dynamics characteristics.For some traffic facilities with complex dynamics characteristics,empirical analysis proves to be very effective,workable and precise. Therefore,by filming the peak flow of the ascending escalator in several stations of Guangzhou Metro and by processing the relevant data,the corresponding diagrams of basic traffic characteristics are established to describe the behaviors of pedestrians in the escalator entrance and on the escalator at a stairway width of 1 meter. The results of the analyses show that the actual escalator capacity is 8655 persons per hour,which accounts for 90% of the theoretical one.
