Class StreetRouter

java.lang.Object

org.opentripplanner.streets.StreetRouter

public class StreetRouter
extends Object

This routes over the street layer of a TransitNetwork. It is a throw-away calculator object that retains routing state and after the search is finished. Additional functions are called to retrieve the routing results from that state.

StreetRouter

public StreetRouter(StreetLayer streetLayer)

Method Detail

getReachedStops

public gnu.trove.map.TIntIntMap getReachedStops()

Returns:

a map from transit stop indexes to their distances from the origin. Note that the TransitLayer contains all the information about which street vertices are transit stops.

getReachedVertices

public gnu.trove.map.TIntIntMap getReachedVertices()

Return a map of all the reached vertices to their distances from the origin

getStopTree

public int[] getStopTree()

Get a distance table to all street vertices touched by the last search operation on this StreetRouter.

Returns:

A packed list of (vertex, distance) for every reachable street vertex. This is currently returning the weight, which is the distance in meters.

setOrigin

public void setOrigin(double lat,
                      double lon)

Parameters:

lat - Latitude in floating point (not fixed int) degrees.

lon - Longitude in flating point (not fixed int) degrees.

setOrigin

public void setOrigin(int fromVertex)

route

public void route()

Call one of the setOrigin functions first.

getTravelTimeToVertex

public int getTravelTimeToVertex(int vertexIndex)
