All Implemented Interfaces:

Serializable, OnboardEdge, PatternEdge

public class TransitBoardAlight
extends TablePatternEdge
implements OnboardEdge

Models boarding or alighting a vehicle - that is to say, traveling from a state off vehicle to a state on vehicle. When traversed forward on a boarding or backwards on an alighting, the the resultant state has the time of the next departure, in addition the pattern that was boarded. When traversed backward on a boarding or forward on an alighting, the result state is unchanged. A boarding penalty can also be applied to discourage transfers. In an on the fly reverse-optimization search, the overloaded traverse method can be used to give an initial wait time. Also, in reverse-opimization, board costs are correctly applied. This is the result of combining the classes formerly known as PatternBoard and PatternAlight.

Constructor Detail

TransitBoardAlight

public TransitBoardAlight(TransitStopDepart fromStopVertex,
                          PatternStopVertex toPatternVertex,
                          int stopIndex,
                          TraverseMode mode)

Boarding constructor (TransitStopDepart --> PatternStopVertex)

TransitBoardAlight

public TransitBoardAlight(PatternStopVertex fromPatternStop,
                          TransitStopArrive toStationVertex,
                          int stopIndex,
                          TraverseMode mode)

Alighting constructor (PatternStopVertex --> TransitStopArrive)

Method Detail

getPattern

public TripPattern getPattern()

Find the TripPattern this edge is boarding or alighting from. Overrides the general method which always looks at the from-vertex.

Specified by:

getPattern in interface PatternEdge

Overrides:

getPattern in class TablePatternEdge

Returns:

the pattern of the to-vertex when boarding, and that of the from-vertex when alighting.

getDirection

public String getDirection()

Description copied from class: Edge

Get a direction on paths where it matters, or null

Overrides:

getDirection in class Edge

Returns:

getDistance

public double getDistance()

Overrides:

getDistance in class Edge

getGeometry

public com.vividsolutions.jts.geom.LineString getGeometry()

Overrides:

getGeometry in class Edge

getMode

public TraverseMode getMode()

getName

public String getName()

Description copied from class: Edge

Gets english localized name

Specified by:

getName in class Edge

Returns:

english localized name

getName

public String getName(Locale locale)

Description copied from class: Edge

Gets wanted localization

Specified by:

getName in class Edge

Parameters:

locale - wanted locale

Returns:

Localized in specified locale name

traverse

public State traverse(State state0)

Description copied from class: Edge

Traverse this edge.

Specified by:

traverse in class Edge

Parameters:

state0 - The State coming into the edge.

Returns:

The State upon exiting the edge.

traverse

public State traverse(State s0,
                      long arrivalTimeAtStop)

NOTE: We do not need to check the pickup/drop off type. TransitBoardAlight edges are simply not created for pick/drop type 1 (no pick/drop).

Parameters:

arrivalTimeAtStop - TODO: clarify what this is.

optimisticTraverse

public State optimisticTraverse(State state0)

Overrides:

optimisticTraverse in class Edge

timeLowerBound

public double timeLowerBound(RoutingRequest options)

Description copied from class: Edge

Returns a lower bound on traversal time given the routing options.

Overrides:

timeLowerBound in class Edge

Returns:

edge weight as a double.

weightLowerBound

public double weightLowerBound(RoutingRequest options)

Description copied from class: Edge

Returns a lower bound on edge weight given the routing options.

Overrides:

weightLowerBound in class Edge

Returns:

edge weight as a double.

getStopIndex

public int getStopIndex()

Description copied from interface: OnboardEdge

The stop index (within the trip) of the stop this edge comes from. This is equivalent to a hop index.

Specified by:

getStopIndex in interface OnboardEdge

Specified by:

getStopIndex in class TablePatternEdge

toString

public String toString()

Overrides:

toString in class Edge
