Abstract

Platform edge doors (PEDs) have been used in various metro stations to improve safety and ventilation conditions, however limited research has been done to estimate the passenger space (PS) in the boarding and alighting process when PEDs are installed. The aim of this study was to estimate the space needed for boarding and alighting at metro stations. The method was based on a mock-up carriage and the relevant portion of the platform at University College London´s Pedestrian Accessibility Movement Environmental Laboratory (PAMELA), in which different load scenarios of boarding and alighting were conducted. The scenarios were based in a preliminary analysis observed at Westminster Station, in which PEDs are installed. To obtain the position of each passenger on the platform a tracking tool was used. The hypothesis of this research was that PS for alighting passengers can be represented as an asymmetrical ellipse, in which the longitudinal and lateral radii changed according to the negotiation with other passengers alighting or waiting on the platform to board the train. Therefore, there is a relationship between PS and the level of interaction, which suggests that passengers adjust their PS to avoid collision. This research can be used by traffic engineers to estimate PS of passengers boarding and alighting when PEDs are used. This in turn can help in designing the platform train interface (PTI) and platforms at transport infrastructures.
