The impact of platform edge doors on passengers boarding and alighting time and platform behaviour
Platform Edge Doors (PEDs) are becoming an international benchmark for metro systems because of their potential to facilitate the transition to fully automated train operation and to reduce the social and operating costs of accidents and obstacles on the platform train interface (PTI).
However, concerns exist that the presence of PEDs may lengthen the dwell time, which can severely hinder service reliability in high-frequency services such as those operated by London Underground (LU).
This paper explores the impact of PEDs on the boarding and alighting time (BAT) and on passenger behaviour from two perspectives: through laboratory experiments under controlled conditions and through the analysis of video footage recorded on LU network.
Both approaches lead to similar conclusions, showing that the presence of PEDs does not have a negative impact on the BAT and does affect passenger behaviour at the platform, inducing a more organised boarding and alighting process where boarders wait beside the door rather than in front of them and give way to alighters more often than without PEDs.
