设屏蔽门的岛式地铁车站站台宽度设计方法

通过视频识别和实地观测,基于乘客候车行为提出岛式站台乘客候车6个阶段站台功能区域转变的方式,遵循乘客安全候车和顺利流通的原则,提出上、下行列车等待区和流通区互不重叠、相互独立的要求,确定考虑等待区长度和流通区宽度的站台宽度设计方法,并与现行规范站台宽度设计方法对比,说明现行方法在实际运行中存在的问题.而新方法符合加设屏蔽门的站台运行特点,可以为轨道站设计提供参考.

Design of Island platform Width at Metro Station Equipped with Screen Door

metro stations have installed platform screen doors (PSD), passengers unevenly gathered in front of screen doors instead of distributing randomly and evenly on platform. A calculation method of island platform width was proposed based on the behavior of passengers. By means of video identification and field observations, the transformation process and size calculation method of main functional areas were proposed, including waiting area and circulation area during the whole processes composed of waiting, alighting and boarding, and dissipating. Subsequently, based on the objectives of safely waiting and smoothly circulating of passengers, and the premise of different functional areas being independent and unoverlapped, a new calculation method of platform width, which is highly related to the length of waiting area and the width of circulating area was put forward. Finally, a comparative study showed that the calculation method overcame and was completely adapted to the defects of traditional method, the behavior characteristics of passengers and the platform operational feature of China. The study results provided a guidance for platform design.
