    • computeLaneChangeAndAcceleration

      public final DirectedLaneMovementStep computeLaneChangeAndAcceleration​(LaneBasedGTU gtu, LateralDirectionality direction, java.util.Collection<Headway> sameLaneGTUs, java.util.Collection<Headway> otherLaneGTUs, Length maxDistance, Speed speedLimit, Acceleration otherLaneRouteIncentive, Acceleration laneChangeThreshold, Duration laneChangeTime) throws GTUException, ParameterException, OperationalPlanException
      Compute the acceleration and lane change.
      Specified by:
      computeLaneChangeAndAcceleration in interface DirectedLaneChangeModel
      Parameters:
      gtu - LaneBasedGTU; the GTU for which the acceleration and lane change is computed
      direction - LateralDirectionality; the direction of the lane we want to change to
      sameLaneGTUs - Collection<Headway>; the set of information about observable GTUs in the current lane (can not be null and may include the gtu)
      otherLaneGTUs - Collection<Headway>; the set of information about 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)
      maxDistance - Length; the maximum distance that the current GTU can drive, e.g. due to a lane drop
      speedLimit - Speed; the local speed limit
      otherLaneRouteIncentive - 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 merge to overtake other traffic
      laneChangeTime - Duration; time spent to overtake
      Returns:
      LaneMovementStep; the result of the lane change and GTU following model
      Throws:
      GTUException - when the position of the GTU on the lane(s) cannot be determined
      ParameterException - in case of a parameter problem.
      OperationalPlanException - if DefaultAlexander perception category is not present

    • applyDriverPersonality

      public abstract Acceleration applyDriverPersonality​(DualAccelerationStep accelerationStep)
      Return the weighted acceleration as described by the personality. This incorporates the personality of the driver to the lane change decisions.
      Parameters:
      accelerationStep - 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

    • getPerception

      public final LanePerception getPerception()
      Specified by:
      getPerception in interface DirectedLaneChangeModel
      Returns:
      the perception.
