北京地铁进出站设施通行瓶颈问题定量分析

为解决高峰时期地铁车站人流密集、流量大而影响乘客顺畅有序进出车站的问题,在对地铁车站进行实地调查的基础上,分析影响乘客进出站通行能力的瓶颈因素;结合调研数据和录像资料,定量研究这些瓶颈设施的实际通过能力,并确定影响乘客通行的瓶颈因素为:安检处、上行楼梯口和自动扶梯;提出安检处的通过能力为2 600人/h,将<地铁设计规范>中自动扶梯通过能力修正为6 100 人/h;进一步提出北京站进出站设施的利用系数,为客流组织和新站设计提供参照依据.

Quantitative Analysis on the Passage Bottlenecks through the Entrances and Exits of Beijing Subway Stations

In the climax of traffic,there are so many people crowded at subway stations that it is hard for them to go through the stations smoothly. In order to solve the problem,this article analyzes the passengers'walking bottlenecks through the station entrances and exits based on actual surveys at subway stations. Referring to the survey data and video materials,quantitative study on the actual transit capacity for walking passages was carried out and the bottlenecks were identified as security checks,entrances f...
