Electronic timetable information
As electronic timetable information Computer programs are referred to, the information about driving connections of public transport can spend.
Range of functions
The functional scope of electronic timetable information systems includes the search for the fastest connection from a given start to a given destination at a desired departure time. In addition, this search can often be refined by specifying, among other things, intermediate stops, certain types of transport, such as B. Long-distance trains can be excluded, the maximum number of transfers can be specified or the walking speed can be set.
As an output from the timetable information system, the user generally receives both the fastest connection and other similar connections. In most cases, the individual means of transport to be used are specified with their departure and arrival times, as well as the individual stops and transfers. Tariff information is provided about this in individual information systems.
In addition to this basic function, some systems also provide information about departures and arrivals at individual stops or route book- like information about individual connections.
history
The first electronic timetable information systems emerged at the end of the 1980s.
A first application for home users was developed in 1987 with Finajour by the company of the same name, the first sales version appeared for the 1989/1990 timetable for Switzerland ( SBB and Swiss private railways ).
As part of the course 90 project of the Deutsche Bundesbahn , HaCon Ingenieur GmbH developed the first electronic timetable information in Germany. For this derives the still of the Deutsche Bahn used HAFAS from system. In addition to this company, the Austrian Federal Railways , the Swiss Federal Railways , as well as other transport associations and authorities use the program as a timetable information system. These systems are supplied with Europe-wide timetable information for the individual rail systems via the European Timetable Center coordination office .
In addition to the above-mentioned system, ten transport authorities in Germany use the electronic timetable information EFA program from MENTZ GmbH for their timetable information. For example, it is used in the DEFAS Bavaria project .
Further electronic timetable information are GEOFOX , MoFahr and public transport .
Between 1997 and 1999, the system of continuous electronic timetable information (DELFI) was developed in Germany as an interface based on XML data between the various timetable information systems.
Mathematical basics
Electronic timetable information calculates the connections using the shortest route algorithms, among other things . In addition, further developments of the so-called Ariadne algorithm are used here.
