Method Details

getFollowingAcceleration

public org.djunits.value.vdouble.scalar.Acceleration getFollowingAcceleration(LaneBasedGtu gtu,
 PerceptionCollectable<HeadwayGtu,LaneBasedGtu> leaders,
 org.opentrafficsim.base.parameters.Parameters settings)
                                                                       throws org.opentrafficsim.base.parameters.ParameterException

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

Overrides:

getFollowingAcceleration in class LinearAcc

Parameters:

gtu - LaneBasedGtu; gtu

leaders - PerceptionCollectable<HeadwayGtu, LaneBasedGtu>; leaders

settings - Parameters; system settings

Returns:

Acceleration; following acceleration of the longitudinal control

Throws:

org.opentrafficsim.base.parameters.ParameterException - if parameter is not present
