Project status



Computer science and engineering

An R&D-project financed by the Swedish Transport Administration (Trafikverket, also formerly known as Banverket), the municipality of Karlshamn and  Blekinge Institute of Technology (www.bth.se). The project is finalised since March 2007 and its continuation started September 2007, within the project OAT+.

The purpose of this project is to support the planning and re-planning of the railway timetable. Since 2002, BTH (Blekinge Tekniska Högskola) has developed an optimization methodology for re-planning of the timetable during disturbances, which has shown good results. Within this project, we aim to continue developing and evaluating this approach.

By considering an existing timetable and specifying desired improvements, our method tries to achieve these improvements by computing best possible modifications and generates a new timetable including meets and overtakes.
