Passengers with Reduced Mobility: Modelling Their Behaviour in Underground Stations

Provides a proposed modelling framework for underground customers with reduced mobility


"Passengers with a range of mobility need to travel through London Underground stations, and it is important that this is taken into account across the organisation. LUL?s existing passenger flow models, currently only represent non-disabled unencumbered passengers, and so do not accurately consider the impact that passengers with mobility difficulties and encumbrances might have at stations. This is clearly a short coming of the existing modelling methodologies. Through this project, the London Underground station modelling and standards team hope to redress this.
This study details the research undertaken to collect the quantitative and qualitative available data that will allow Persons with Reduced Mobility (PRMs) to be incorporated into station models. Various sources of information have been used - the Underground Users Survey, as well as empirical counts.
This study has produced a classification of PRMs and calculated their volume as a proportion of total passenger demand during different times of day. PRMs have been classified as either Wheelchair bound customers, passengers with permanant of temporary physical mobility impairments, passengers with medium size luggage, passengers with heavy luggage, and passengers with small children. The study has demonstrated that all customers fall under at least one PRM category at various points during their lives. Further analysis has been undertaken to understand the space requirements (in terms of customer size) and movement characteristics of PRMs in the context of Underground Stations. The results of the study have implications on the provision of step free access at stations - the findings help understanding of the particular requirements of the different PRM categories"
