        Compute the acceleration and lane change.
        Specified by:
        computeLaneChangeAndAcceleration in interface LaneChangeModel
        Parameters:
        gtu - LaneBasedGTU; the GTU for which the acceleration and lane change is computed
        sameLaneGTUs - Collection<Headway>; the set of observable GTUs in the current lane (can not be null and may include the gtu)
        preferredLaneGTUs - Collection<Headway>; the set of observable GTUs in the adjacent lane where GTUs should drive in the absence of other traffic (must be null if there is no such lane)
        nonPreferredLaneGTUs - Collection<Headway>; the set of observable GTUs in the adjacent lane into which GTUs should merge to overtake other traffic (must be null if there is no such lane)
        speedLimit - Speed; the local speed limit
        preferredLaneRouteIncentive - Acceleration; route incentive to merge to the adjacent lane where GTUs should drive in the absence of other traffic
        laneChangeThreshold - Acceleration; threshold that prevents lane changes that have very little benefit
        nonPreferredLaneRouteIncentive - Acceleration; route incentive to merge to the adjacent lane into which GTUs should merge to overtake other traffic
        Returns:
        LaneMovementStep; the result of the lane change and GTU following model
        Throws:
        org.opentrafficsim.base.parameters.ParameterException - in case of a parameter problem.
        OperationalPlanException - if DefaultAlexander perception category is not present.

      • applyDriverPersonality

        public abstract Acceleration applyDriverPersonality​(DualAccelerationStep accelerationSteps)
        Return the weighted acceleration as described by the personality. This incorporates the personality of the driver to the lane change decisions.
        Parameters:
        accelerationSteps - DualAccelerationStep; the DualAccelerationStep that contains the AccelerationStep that the reference GTU will make and the AccelerationStep that the (new) follower GTU will make
        Returns:
        Acceleration; the acceleration that the personality of the driver uses (in a comparison to a similarly computed acceleration in the non-, or different-lane-changed state) to decide if a lane change should be performed
