Effect of Stair and Escalator Combination Form on Platform Flow Performance in Metro Stations
The safety level and efficiency of passenger flow on platform in metro station is affected by vertical pedestrian facilities including stairs and escalators which connect different floors. Focusing on the effect of stair and escalator combination form on pedestrian flow performance, the authors first build a passenger flow model for an island metro platform and then investigate in total six different scenarios. In each scenario, there are two vertical pedestrian facilities. Each facility is composed of one stair walkway, one ascending and one descending escalator. Under the influence of different stair-escalator combination layout, the passenger flow patterns were investigated by considering the volume of boarding and alighting passengers, and the time interval between two successively arrived trains at the opposite sides of the same platform. Simulation results indicate that stair-escalator combination form influents platform flow performance. When the authors put a descending escalator in between a stair and an ascending escalator, the pedestrian efficiency is the highest; however on contrast, when they put an ascending escalator in between the stair and the descending escalator, the pedestrian efficiency is the lowest. It is suggested that the descending escalator should be placed in middle of the ascending escalator and the stair on metro platform, which may adapt to a shorter time interval between two successively arriving trains at the opposite sides of the same platform.
