Passenger flows and dwell times for commuter trains in Stockholm

Kuipers, Ruben LU ; Palmqvist, Carl-William LU orcid and Olsson, Nils LU (2021) 9th International Conference on Railway Operations Modelling and Analysis (ICROMA) – RailBeijing
Abstract
This study investigates how the volume and flow of passengers affect dwell times, using data from commuter trains in Stockholm. We show that dwell times often take longer than scheduled and that most station stops involve rather limited numbers of passengers. Improving the performance at these stops with small volumes can thus have a sizeable impact on the overall on-time performance. We find a quadratic relationship between the number of passengers and the likelihood of dwell times taking longer than scheduled. Dwell times are shortest when the flow of passengers is entirely in one direction, boarding or alighting, for both lower and higher passenger volumes. If both boarding and alighting flows are present, it is best that they are as... (More)

Dwell times are shortest when the flow of passengers is entirely in one direction, boarding or alighting, for both lower and higher passenger volumes. If both boarding and alighting flows are present, it is best that they are as balanced as possible in the case of lower passenger volumes. The influence of this proportion is less prominent when passenger volumes are higher. Scheduled dwell times should thus be based both on the expected volume of passengers and on the expected proportion of boarding and alighting passengers. (Less)
