Constructor Detail

LinkLocation

public LinkLocation(Link link,
                    double fractionalLongitudinalPosition)

Parameters:

link - The link of the location of a point relative to the GTU.

fractionalLongitudinalPosition - The fractional position (between 0.0 and 1.0) of the reference point on the link.

LinkLocation

public LinkLocation(Link link,
                    Length position)

Parameters:

link - The link of the location of a point relative to the GTU.

position - The position as a length of the reference point on the link.

Method Detail

getLink

public final Link getLink()

Returns:

lane.

getFractionalLongitudinalPosition

public final double getFractionalLongitudinalPosition()

Returns:

fractionalLongitudinalPosition.

getLongitudinalPosition

public final Length getLongitudinalPosition()

Returns:

position as a length as a traveled length on this link.

distance

public final Length distance(LinkLocation loc)

Returns the distance to another LinkLocation. If the other location is in front of us, the distance is positive. If it is behind us, it is negative.

Parameters:

loc - the link location to find the distance to.

Returns:

the distance to another LinkLocation.

toString

public final String toString()

Overrides:
