Integrated Planning in Public Transport – DFG-Research Group FOR 2083

Timetable information systems (e.g. DB Navigator) and journey planners for road networks (e.g. Google-Maps- and Bing-Maps-Routeplanning or TomTom-navigation system) are some of the most used information systems. Nowadays, useres expect more extensive information than just the computation of fastest route. The possibility to find new or alternative routes as a response to current traffic conditions respectively delays is an obvious requirement for modern journey planning systems. Likewise it is a necessity to integrate different modes of transportation, such as intercity buses or car sharing as supplement for public transport.

In light of novel alternative mobility concepts, new information systems that provide “real” alternatives somewhere in between public and private transport will be expected in the future. Notable examples for this are the recent development of long distance bus lines, car sharing concepts like “Stadtmobil”, modern ride sharing services like flinc, or the bike and car rental offered by Deutsche Bahn. Furthermore, today's user expect not only a fastest route, but “best” routes with respect to their personal preferences.

Existing journey planning systems, such as the aforementioned ones, resolve these challenges only partially. However, current timetable information systems do not consider other modes of transportation throughout the whole journey, but at most for arriving and departing from public transport; thus no “truly” multimodal journeys are computed. Similarly, information concerning current delays is provided during the journey, but no real alternative routes incorporating current delays in the public transportation network are offered.
