Modelling the distribution of passengers waiting to board the train at metro stations

摘要

The platform train interface (henceforth PTI) is the most complex space in which the boarding and alighting takes place (Seriani and Fernandez, 2015a). The way (e.g. movement) that passengers go from the platform to the train (boarding) or from the train to the platform (alighting) is a very important issue that affects the safety and efficiency of metro stations. With respect to safety, in the case of the UK, more than 3 billion interactions each year take place in the national network, in which 21% of the safety risks (injuries and fatalities) and 48% of the fatality risks to passengers are produced at the PTI zone (RSSB, 2015). With respect to the London Underground, the total network provides around 4.69 million trips per day with a high peak of demand between 8 and 9 a.m., requiring one train every 2 or 3min at metro stations such as Westminster (38,241 trips/day) and Green Park (58,814 trips/day) on the Jubilee Line (TfL, 2018).
