Predicting and mitigating small fluctuations in station dwell times

Predicting and mitigating small fluctuations in station dwell times
Predicting and mitigating small fluctuations in station dwell times
On busy railway networks, exceeding station dwell times by only a few seconds
can adversely affect overall network performance. However, while these performance impacts are well known, the causes of small dwell time perturbations are not widely understood (or are not widely communicated at an operational level) and exhibit a high level of spatial and temporal variation. A lack of information and understanding makes it difficult to implement effective mitigation measures to reduce the occurrence and impact of such delays.

For this paper On Train Monitoring Recorder (OTMR) data were obtained
for a large number of services over a 14-month period, which included the wheel
stop and wheel start timings associated with station stops at a one second resolution. These were combined with other relevant data sources in order to
investigate small fluctuations in station dwell time. An interface for communicating these variations to railway operating staff was developed, along with models to predict future dwell time fluctuations, potentially enabling mitigation measures to be implemented.

Abstract

On busy railway networks, exceeding station dwell times by only a few seconds
can adversely affect overall network performance. However, while these performance impacts are well known, the causes of small dwell time perturbations are not widely understood (or are not widely communicated at an operational level) and exhibit a high level of spatial and temporal variation. A lack of information and understanding makes it difficult to implement effective mitigation measures to reduce the occurrence and impact of such delays.

For this paper On Train Monitoring Recorder (OTMR) data were obtained
for a large number of services over a 14-month period, which included the wheel
stop and wheel start timings associated with station stops at a one second resolution. These were combined with other relevant data sources in order to
investigate small fluctuations in station dwell time. An interface for communicating these variations to railway operating staff was developed, along with models to predict future dwell time fluctuations, potentially enabling mitigation measures to be implemented.
