Class RelativePosition

java.lang.Object

org.opentrafficsim.core.gtu.RelativePosition

All Implemented Interfaces:

Serializable

public class RelativePosition
extends Object
implements Serializable

A RelativePosition is a position on a GTU; e.g. the front, rear, position of the driver, etc.
A RelativePosition stores the offset of the position from the reference position of the GTU.
