      • IDMPlus

        public IDMPlus​(DesiredHeadwayModel desiredHeadwayModel,
               DesiredSpeedModel desiredSpeedModel)
        Constructor with modular models for desired headway and desired speed.
        Parameters:
        desiredHeadwayModel - DesiredHeadwayModel; desired headway model
        desiredSpeedModel - DesiredSpeedModel; desired speed model

    • Method Detail

      • getName

        public final String getName()
        Return the name of the car-following model.
        Returns:
        name of the car-following model

      • getLongName

        public final String getLongName()
        Return the complete name of the car-following model.
        Returns:

                                             throws ParameterException
        Combines an interaction term with the free term. There should be at least 1 leader for this method.
        Specified by:
        combineInteractionTerm in class AbstractIDM
        Parameters:
        aFree - Acceleration; Free term of acceleration.

        speed - Speed; Current speed.
        desiredSpeed - Speed; Desired speed.
        desiredHeadway - Length; Desired headway.
        leaders - PerceptionIterable<? extends Headway>; Set of leader headways (guaranteed positive) and speeds, ordered by headway (closest first).
        Returns:
        Combination of terms into a single acceleration.
        Throws:
        ParameterException - In case of parameter exception.
