Support for merging multiple public transport schedules (with pt2matsim)? about matsim-code-examples

[polettif]

I don't know about an established way but there's ScheduleTools.mergeSchedules which, together with ScheduleTools.createVehicles(), could be used to achieve this. Doing this before running PTMapper is the way to go. Combining xml files should work as well I think.

Great, thanks for the hint! ScheduleTools does the job well:

static final String COORDINATE_SYTEM = "epsg:XXXXX";
static final List<String> GTFS_DIRS = Arrays.asList("a", "b", "c");
static final String TRANSIT_SCHEDULE_NOT_YET_MAPPED_TO_ROADS = "transit_schedule_not_yet_mapped_to_roads.xml";
static final String TRANSIT_VEHICLES = "transit_vehicles.xml";

public static void prepareTransitSchedules() {
	TransitSchedule transitSchedule = prepareTransitSchedule(GTFS_DIRS.get(0));
	for(String gtfsDir : GTFS_DIRS.subList(1, GTFS_DIRS.size())) {
		TransitSchedule additionalSchedule = prepareTransitSchedule(gtfsDir);
		ScheduleTools.mergeSchedules(transitSchedule, additionalSchedule);
	}
	
	Vehicles transitVehicles = VehicleUtils.createVehiclesContainer();
	ScheduleTools.createVehicles(transitSchedule, transitVehicles);
	
	ScheduleTools.writeTransitSchedule(transitSchedule, TRANSIT_SCHEDULE_NOT_YET_MAPPED_TO_ROADS);
	ScheduleTools.writeVehicles(transitVehicles, TRANSIT_VEHICLES);
}

private static TransitSchedule prepareTransitSchedule(String gtfsDir) {
	String param = GtfsConverter.DAY_WITH_MOST_TRIPS;
	GtfsFeed gtfsFeed = new GtfsFeedImpl(gtfsDir);
	GtfsConverter converter = new GtfsConverter(gtfsFeed);
	converter.convert(param, COORDINATE_SYTEM);
	return converter.getSchedule();
}
