PT2MATSim

Build Status

PT2MATSim is a package to convert public transit data from GTFS, HAFAS or OSM to a completely mapped MATSim schedule.

Mapping example

There are multiple public transit schedule data formats, widely used formats are GTFS and HAFAS. Numerous GTFS feeds are publicly available (see transitfeeds.com or transit.land), otherwise these files have to be obtained from the public transit agency. The Swiss public transit schedule is available GTFS and HAFAS format via opentransportdata.swiss. Public transit data feeds can be converted to unmapped MATSim transit schedules using the classes Gtfs2Transitschedule or Hafas2TransitSchedule. It is possible to convert public transit information from OpenStreetMap files (Osm2TransitSchedule). However, OSM currently does not contain any temporal information, the accuracy of the schedule data varies and is usually not sufficient to be used for simulations.

Unmapped transit schedules lack information on the links used by vehicles and only contain the stop sequence for transit routes. Generating these links (i.e. the path a vehicle takes on a network) is called "mapping", a process done by the PublicTransitMapper. It implements an algorithm that uses an abstract graph to calculate the least cost path from the transit route's first to its last stop with the constraint that the path must contain a so called link candidate for every stop. The result is a mapped transit schedule and a modified network.

Tools to validate and rudimentarily edit the mapped schedule are also part of the package.
