Using Multi-level Graphs for Timetable Information in Railway Systems
[chapter]
2002
Lecture Notes in Computer Science
Preserved Fulltext
For one specific application scenario from the field of timetable information in public transport, we perform a detailed analysis and experimental evaluation of shortest path computations based on multi-level ...
Scenarios where large numbers of on-line queries for shortest paths have to be processed in real-time appear for example in traffic information systems. ...
We would like to thank Martin Holzer for his help in part of the implementations and experiments. ...

The current state-of-the-art in timetable analysis in the presence of disruptions is to use railway microsimulation, which typically yields detailed results on infrastructure or timetable performance. ...
Although there is some room for improvements in accuracy, the new approach appears promising, and we found no evidence against its suitability in the presence of disruptions. ...
From the timetable, nodes of a graph are constructed, containing the information when a train is planned to arrive at and depart from a point on the railway network. ...

As demand for passenger and freight transport on Britain's railways increases, providing additional capacity and making the best use of the existing infrastructure are priorities for the industry. ...
Since the stations and junctions forming the nodes of the railway network tend to form the constraints on route and network capacity, improved understanding of their operation and capacity characteristics ...
Capacity utilisation assessments inform both of the above objectives, in that (i) the greater the number of trains being run for a given level of capacity utilisation, the greater the level of capacity ...
