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

Abstract:

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 the defects of traditional method, and was completely adapted to the behavior characteristics of passengers and the platform operational feature of China. The study results provided a guidance for platform design.
