Class TrafficLightSensor

java.lang.Object

nl.tudelft.simulation.event.EventProducer

org.opentrafficsim.road.network.lane.object.sensor.TrafficLightSensor

All Implemented Interfaces:

Serializable, EventListener, nl.tudelft.simulation.event.EventListenerInterface, nl.tudelft.simulation.event.EventProducerInterface, NonDirectionalOccupancySensor

public class TrafficLightSensor
extends nl.tudelft.simulation.event.EventProducer
implements nl.tudelft.simulation.event.EventListenerInterface, NonDirectionalOccupancySensor, nl.tudelft.simulation.event.EventProducerInterface

This traffic light sensor reports whether it whether any GTUs are within its area. The area is a sub-section of a Lane. This traffic sensor does not report the total number of GTUs within the area; only whether that number is zero or non-zero.
