Optimal rerouting of short-turning trains during track obstructions

Railway trafic controllers have only limited decision support to deal with disruptions. The aim of this research is to provide an algorithm to compute conflict-free routes for trains that cannot continue their planned operation due to a track obstruction. In case of complete blockage, trains need to short-turn at the closest possible station to...

Review of railway disruption management practice and literature

This paper investigates the challenges of railway traffic controllers in dealing with big disruptions and the kind of support tools that could help to improve their task in terms of performance and lead time. The disruption handling process can be partitioned into three phases according to the bathtub model and to each phase the essential...

Integrated Decision Support Tools for Disruption Management

During railway operations unexpected events can require railway operators and infrastructure managers to adjust their schedules. In this research we investigate the disruption management process. More specifically, we come up with an architecture and algorithmic framework which railway operators could use for decision support during disruptions....

Models for Predictive Railway Traffic Management

The potential growth in transport demand in the next decade and beyond requires a change from reactive to proactive traffic control to maintain and improve the reliability of railway traffic. In order to enable an anticipative approach to traffic management, it is necessary to develop the tools for monitoring, prediction and optimisation of the...

Schiphol's dynamic traffic Management: A case study on rescheduling

Around the railway station of Schiphol, railway traffic is controlled by an automated dynamic traffic management system (DVM). This system is not optimal for the future service pattern of NS and NS Hispeed. My research explores the possibilities of a new DVM by analysing different rescheduling elements by means of microsimulations in OpenTrack.

Performance of Crossovers in the Dutch Railway Network: Case Study for Amsterdam and Rotterdam

ProRail Traffic Control would like to have examined what the performance of crossovers for rescheduling is in case of partial obstructions. The need for quantitative information about the performance of crossovers in The Netherlands has grown. The research is intended to fill this knowledge gap by investigating the performance of crossovers in...
