Class DistractionField

org.opentrafficsim.road.gtu.lane.perception.mental.DistractionField

All Implemented Interfaces:

EventListener, EventListener

public class DistractionField
extends Object
implements EventListener

This class perceives all distractions. It stores information on lane, odometer and task demand per distraction. For distraction objects that are behind, the information on odometer allows active distraction for some distance beyond the distraction object. This class listens to lane changes to update the relevant lane information. An instance of this class should be shared among different instances of tasks which each can request the total level of distraction given the filter each supplies to the getDistraction(BiFunction) method.
