Class TransportNetwork

java.lang.Object

org.opentripplanner.transit.TransportNetwork

All Implemented Interfaces:

Serializable

public class TransportNetwork
extends Object
implements Serializable

This is a completely new replacement for Graph, Router etc. It uses a lot less object pointers and can be built, read, and written orders of magnitude faster.

OSM PBF files are fragments of a single global database with a single namespace. Therefore it is valid to load more than one PBF file into a single OSM storage object. However they might be from different points in time, so it may be cleaner to just map one PBF file to one OSM object. On the other hand, GTFS feeds each have their own namespace. Each GTFS object is for one specific feed, and this distinction should be maintained for various reasons.

fromDirectory

public static TransportNetwork fromDirectory(File directory)

testRouting

public void testRouting()

Test combined street and transit routing.

getGridPointSet

public PointSet getGridPointSet()

TODO cache this grid.

Returns:

an efficient implicit grid PointSet for this TransportNetwork.

getLinkedGridPointSet

public LinkedPointSet getLinkedGridPointSet()

TODO cache this grid.

Returns:

an efficient implicit grid PointSet for this TransportNetwork, pre-linked to the street layer.
