Constructor Detail

PlatoonSizes

public PlatoonSizes(Duration threshold)

Constructor.

Parameters:

threshold - Duration; maximum time between two vehicles that are considered to be in the same platoon

Method Detail

identity

public org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement identity()

Returns the initial value before accumulation.

Specified by:

identity in interface Detector.DetectorMeasurement<org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement,List<Integer>>

Returns:

C; initial value before accumulation

accumulateEntry

public org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement accumulateEntry(org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement cumulative,
                                                                                                      LaneBasedGTU gtu,
                                                                                                      Detector loopDetector)

Returns an accumulated value for when the front reaches the detector.

Specified by:

accumulateEntry in interface Detector.DetectorMeasurement<org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement,List<Integer>>

Parameters:

cumulative - C; accumulated value

gtu - LaneBasedGTU; gtu

loopDetector - LoopDetector; loop detector

Returns:

C; accumulated value

accumulateExit

public org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement accumulateExit(org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement cumulative,
                                                                                                     LaneBasedGTU gtu,
                                                                                                     Detector loopDetector)

Returns an accumulated value for when the rear leaves the detector. GTU's may trigger an exit without having triggered an entry due to a lane change. Reversely, GTU's may not trigger an exit while they did trigger an entry.

Specified by:

accumulateExit in interface Detector.DetectorMeasurement<org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement,List<Integer>>

Parameters:

cumulative - C; accumulated value

gtu - LaneBasedGTU; gtu

loopDetector - LoopDetector; loop detector

Returns:

C; accumulated value

isPeriodic

public boolean isPeriodic()

Specified by:

isPeriodic in interface Detector.DetectorMeasurement<org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement,List<Integer>>

Returns:

boolean; whether the measurement aggregates every aggregation period (or only over the entire simulation)

aggregate

public List<Integer> aggregate(org.opentrafficsim.road.network.lane.object.sensor.Detector.PlatoonMeasurement cumulative,
                               int count,
                               Duration aggregation)

Returns an aggregated value.

getName

public String getName()

Returns the value name.

Specified by:

stringValue

public String stringValue(List<Integer> aggregate,
                          String format)

Returns a string representation of the aggregate result.
