4. Deutsche Bahn: On time means depart earlier in future

So far we were used to the rule that up to the scheduled time it was still possible to jump into the train. From now on, the train will start rolling already, i.e. the doors have to be shut earlier. Something like this we see already in the short-distance transport of a German large city, it is allowed to depart already 30 seconds before scheduled departure time. We do not have to understand this, but it is the way it is. We simply need to know it. 

5. Efficient Timetable Information in the Presence of Delays

Authors: Matthias Müller-Hannemann, Mathias Schnee Abstract: The search for train connections in state-of-the-art commercial timetable information systems is based on a static schedule. Unfortunately,public transportation systems suffer from delays for various reasons. Thus, dynamic changes of the planned schedule have to be taken into account. A system that has access to delay information about trains (and uses this information within search queries) can provide valid alternatives in case a connection does not work. Additionally, it can be used to actively guide passengers as these alternatives may be presented before the passenger is already stranded at a station due to an invalid transfer.

6. Finding All Attractive Train Connections by Multi-criteria Pareto Search

Authors: Matthias Müller-Hannemann and Mathias Schnee Abstract: We consider efficient algorithms for timetable information in public transportation systems under multiple objectives like, for example, travel time, ticket costs, and number of interchanges between different means of transport. In this paper we focus on a fully realistic scenario in public railroad transport as it appears in practice while most previous work studied only simplified models.  

13. The mobility information system MOTIS

To plan a journey: For many internet platforms and on smartphones this still requires a pre-decision to be made regarding a means of transport (airplane, train, car etc) as well as the selection of transition point/s from the ”world of the traveller“ to the “world of the transport company“, i.e. train stations, bus stations, airports etc. More and more innovative IT companies in cooperation with transport companies are providing tools to plan the journey a bit more intelligently.
