Passengers’ experience in underground non-transfer metro stations: The impact of spatial characteristics

Abstract

Underground spaces have emerged as a promising solution for enhancing the overall quality of life in cities by allowing for better land use, reducing noise, and improving air quality. However, the subterranean placement of non-infrastructure facilities gives rise to numerous apprehensions, predominantly concerning the experience of their users. The underground environment may evoke fears and anxieties, disrupt cognitive and physiological responses, and affect personal safety. This paper examines the extent to which the specific spatial characteristics of underground non-transfer metro stations influence the passenger experience measured by the subjective indicators of comfort and safety. The research combines survey data collected from 1400 users with spatial data obtained from space syntax analyses and field investigations of 28 underground metro stations in Warsaw, Poland. Based on the results of multiple regression analysis, a set of spatial features that affect user comfort and safety was identified. The results show that passengers’ experience is shaped by several architectural characteristics of metro ‘stations, as well as their accessibility and position in the city and neighbourhood. Among the most influential architectural features is the configuration of the concourse level followed by the geometry of the platform hall and the use of art elements. Based on the findings presented in the study, potential design strategies that could improve the user experience are proposed and discussed. The recommended approaches offer valuable insights for designers aiming to improve the existing metro stations and facilitate more effective designs for new underground facilities.
