public class AnticipationTrafficPerception
extends AbstractPerceptionCategory<LaneBasedGtu,LanePerception>
implements TrafficPerception

Traffic perception using neighbors perception. Speed is anticipated as in the LMRS. Density is simply distance of the farthest leader divided by the number of leaders.
