Delay Propagation on a Suburban Railway Network

EasyChair Preprint no. 2517

2 pagesDate: January 31, 2020


Understanding and predicting delays is a central task for any railway system, but it is made much more difficult by interactions between trains. We propose a new model for the delay propagation phenomenon, which takes into account infrastructure constraints without assuming knowledge of the resource conflicts linking trains with one another. Our approach relies on a set of hidden variables called the network jam, structured as a Dynamic Bayesian Network to enable spatial propagation. We also present a statistical analysis of the minimax estimation error, a variational inference method and numerical tests on simulated and real data.

Keyphrases: Dynamic Bayesian Network, Railway Operations, Train delay prediction, variational inference

  year = {EasyChair, 2020}}
