org.opentrafficsim.core.network.lane.AbstractSensor

org.opentrafficsim.core.network.lane.stop.StopLineLane

All Implemented Interfaces:

Serializable, Comparable<Sensor>, Sensor

public class StopLineLane
extends AbstractSensor

This is a sensor that detects GTU's on a lane, and is able to pass information by sending a pulse with a time stamp.

Constructor and Description
StopLineLane(Lane<?,?> lane, DoubleScalar.Rel<LengthUnit> longitudinalPositionFromEnd) Place a sensor that is triggered with the back of the GTU one ulp (see Math.ulp(double d)) before the end of the lane to make sure it will always be triggered, independent of the algorithm used to move the GTU.

Constructor Detail

StopLineLane

public StopLineLane(Lane<?,?> lane,
                    DoubleScalar.Rel<LengthUnit> longitudinalPositionFromEnd)

Place a sensor that is triggered with the back of the GTU one ulp (see Math.ulp(double d)) before the end of the lane to make sure it will always be triggered, independent of the algorithm used to move the GTU.

Parameters:

lane - The lane for which this is a sensor.

longitudinalPositionFromEnd - longitudinal position from the end TODO change for position, not from the end.

Method Detail

trigger

public final void trigger(LaneBasedGTU<?> gtu)

Trigger an action on the GTU. Normally this is the GTU that triggered the sensor. The typical call therefore is sensor.trigger(this);.
For this method, we assume that the right sensor triggered this method. In this case the sensor that indicates the front of the GTU. The code triggering the sensor therefore has to do the checking for sensor type.

Parameters:

gtu - the GTU for which to carry out the trigger action.

createStopGTU

protected final void createStopGTU(OTSDEVSSimulatorInterface simulator)
                            throws RemoteException

Set up the block.

Parameters:

simulator - the simulator for the stop GTU

Throws:

RemoteException - on communications failure

removeStopGTU

protected final void removeStopGTU()

Remove the block.

toString

public String toString()

Overrides:

toString in class Object
