Project title

Predicting and mitigating small fluctuations in station dwell times (COF-INP-03)

  • Project number:

    COF-INP-03
  • Topic:

    Operations
  • Status:

    Underway

Project Summary

The aim of this project is to develop models capable of making real time predictions of expected variations in station dwell time, along with an interface that communicates these variations to railway staff, so that appropriate mitigation measures are implemented.

Project Abstract

Project Briefs are hosted on www.rssb.co.uk
The amount of time spent by a train in a station (the dwell-time) can have a big impact not just the punctuality of the individual train, but on the performance and reliability of an entire railway network.  Delays can quickly become compounded, especially at busy and congested stations.  At one level, it is desirable to reduce dwell times, in order to improve throughput and increase the capacity of the network.  At another level, it is important to reduce fluctuations in dwell times, because these fluctuations can make it hard for operators to plan effectively to avoid disruption.  Train running and delay data are typically not recorded at a high temporal resolution (delay attribution data only provides information concerning delays of three minutes or more), making it hard to monitor smaller fluctuations in dwell times, which can still have big impacts overall on train and network performance.
