Method Details

delayActuation

public org.djunits.value.vdouble.scalar.Acceleration delayActuation(org.djunits.value.vdouble.scalar.Acceleration desiredAcceleration,
 LaneBasedGtu gtu)

Delays the actuation of acceleration.

Parameters:

desiredAcceleration - desired acceleration

gtu - gtu

Returns:

delayed acceleration

getAcceleration

public Optional<org.djunits.value.vdouble.scalar.Acceleration> getAcceleration(LaneBasedGtu gtu,
 Parameters settings)

Description copied from interface: LongitudinalControl

Calculate acceleration.

Specified by:

getAcceleration in interface LongitudinalControl

Parameters:

gtu - controlled GTU

settings - system settings

Returns:

level of acceleration, may be empty if the controller is unable to deal with a situation

getDesiredAcceleration

 PerceptionCollectable<PerceivedGtu,LaneBasedGtu> leaders,
 Parameters settings)
                                                                              throws ParameterException

Returns the desired acceleration from the longitudinal control.

Parameters:

gtu - gtu

leaders - leaders

settings - system settings

Returns:

desired acceleration

Throws:

ParameterException - if parameter is not present
