Method Detail

getDesiredAcceleration

public final Acceleration getDesiredAcceleration(LaneBasedGTU gtu,
                                                 PerceptionCollectable<HeadwayGTU,LaneBasedGTU> leaders,

                                          throws ParameterException

Returns the desired acceleration from the longitudinal control.

Specified by:

getDesiredAcceleration in class AbstractActuatedControl

Parameters:

gtu - LaneBasedGTU; gtu

leaders - PerceptionCollectable<HeadwayGTU, LaneBasedGTU>; leaders

settings - Parameters; system settings

Returns:

Acceleration; desired acceleration

Throws:

ParameterException - if parameter is not present

getFollowingAcceleration

public abstract Acceleration getFollowingAcceleration(LaneBasedGTU gtu,
                                                      PerceptionCollectable<HeadwayGTU,LaneBasedGTU> leaders,
                                                      Parameters settings)
                                               throws ParameterException

Returns the following acceleration of the longitudinal control. This method is only invoked if there is at least 1 leader.

Parameters:
