Timetable Optimisation

TTZ: Trennung Trasse Zug (Separation of Train and Train Path)

With Regulation (EU) No 913/2010 concerning a European rail network for competitive freight, the European Union has mandated the installation of rail corridors for cross-border freight traffic in order to increase quality and competitiveness of international rail freight transport. In particular, infrastructure managers are required to provide pre-defined train paths (so-called system train paths) through these corridors which can be requested by railway undertakings for the operation of cross-border freight trains.

Within the project neXt, BVU in cooperation with DB Netz AG has developed a software solution for allocating system train paths to the customers' timetable requests. Our solution features the following highlights:

  • Network-wide routing on the microscopic infrastructure (track level)
  • Exact calculation of ride times taking into account all relevant determining factors
  • Automatic allocation of system train paths to timetable requests
  • Prevention of conflicting allocations using an integrated conflict detection and resolution module

BVU has also developed a graphical user interface for use by the specialists at DB Netz. The interface can be used for visualising system train paths, timetable requests and the resulting allocations.

From a technical point of view, our solution boasts the following features:

  • Platform independence (Windows, Linux, ...)
  • Designed for 64 bit architectures
  • Modular software architecture
  • High scalability using parallelisation
  • Service oriented architecture (SOA)
  • Agile development
