Research project: Predicting and mitigating small fluctuations in station dwell times - Dormant

Currently Active: 

Developing models and mapping tools to understand and mitigate against fluctuations in train dwell times at railway stations.

Start date: 19/03/2018
End date: 30/04/2019

The amount of time spent by a train in a station (the dwell-time) can have a big impact not just on 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.

GeoData researchers worked closely with colleagues in the Transportation Research Group, collaborating with Rail Industry stakeholders to analyse large volumes of data, develop prediction models and deliver interactive visualisation tools to explore and interact with the data.
