Dwell Time Delays for Commuter Trains in Stockholm and Tokyo

Palmqvist, Carl-William LU orcid ; Tomii, Norio and Ochiai, Yasufumi (2019) RailNorrköping
Abstract
The paper analyses dwell time delays for commuter trains in Stockholm and
Tokyo. In both cities, small dwell time delays of at most five minutes make
up around 90% of the total delays. Therefore, it is valuable to understand
and deal with these disturbances. To this end, we use high resolution data on
dwell times and passenger counts from both countries over the last several
years. We find that these data alone can explain about 40% of the variation
in dwell time delays and produce simple models which can be used in
practice to assign more appropriate dwell times. A change of 15 passengers
per car, in Tokyo translates to a delay of about one second. For every 10
remaining passengers per door in... (More)

per car, in Tokyo translates to a delay of about one second. For every 10
remaining passengers per door in Stockholm, the delay increases by about
one second, and one boarding or alighting passenger per door corresponds
to about 0.4 seconds of delay. We also find that trains in Tokyo are much
more congested than in Sweden, and that at most stations in the latter, the
exchange of passengers is modest. In both cities, the range of dwell time
delays is quite narrow, with between 40 and 50 seconds separating the 5th
and 95th percentiles. This indicates further that most delays, by far, are very
small, and that even small adjustments to dwell times can make a big
difference in the overall picture. To facilitate such improvements, key
stakeholders and practitioners are closely involved with the research. (Less)
