Analysis of Flow Characteristics and Step Size of Escalators at Metro Stations

Abstract

This paper discusses the analysis of flow characteristics on escalators and examines the adequacy of step size. The study was carried out on nine escalators at three metro stations in New Delhi, the capital city of India. Data were collected during morning and evening peak flow periods. Peak flows on the escalators being studied are observed to be higher during evening period as compared to the morning period. Flow values are quite high when compared with flow values at metro stations in China or England or on similar facilities at railway stations. Maximum density was found higher as compared to that reported in China and England and comparable to that at railway stations in India. Space per person was found comparable to the reported values. Relationships between flow characteristics were also developed. Step dimension adequacy was checked and suggested to be modified in the light of person body dimension reported in different guidelines. The outcome will assist the planners to take considered decisions related to escalators.
