Efficient real‐time re‐scheduling of trains during disturbances

This project is financed by Trafikverket and is a continuation of the previous research projects OAT (Omplanering Av Tåglägen) and OAT+ (both financed by Trafikverket). Part of the project team are mainly Magdalena Grimm and Åke Lundberg at Trafikverket as well as Prof. Håkan Grahn, Dr. Johanna Törnquist Krasemann, Ph D student Syed Muhammad Zeeshan Iqbal and project assistant Sara Solanti at Blekinge Institute of Technology.

As the railway traffic networks become more and more saturated and where even small disturbances can propogate and have severe consequences, the need for efficient re‐scheduling support for the traffic managers is evident. In the previous research projects OAT and OAT+ mathematical models describing how the traffic can be re‐scheduled have been developed as well as optimization‐based algorithms to solve the re‐scheduling problem. These models and methods serve to provide the traffic managers in real‐time with suggestions on how to optimally re‐schedule the traffic based on information relevant to make a good plan and in line with the objectives and deliverables Trafikverket has assigned to. In this project, the approach will be further developed with the use of multi‐threading and to be tested in a practical environment during 2012.
