  • Field Details

  • Constructor Details

    • FixedLaneChangeModel

      public FixedLaneChangeModel​(LateralDirectionality laneChange)
      Construct a FixedLaneChangeModel.
      Parameters:
      laneChange - LateralDirectionality; the lane change that (always) be returned by this FixedLaneChangeModel.

  • Method Details

    • computeLaneChangeAndAcceleration

      public final LaneMovementStep computeLaneChangeAndAcceleration​(LaneBasedGTU gtu, Collection<Headway> sameLaneTraffic, Collection<Headway> rightLaneTraffic, Collection<Headway> leftLaneTraffic, Speed speedLimit, Acceleration preferredLaneRouteIncentive, Acceleration laneChangeThreshold, Acceleration nonPreferredLaneRouteIncentive) throws GTUException, ParameterException
      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
      sameLaneTraffic - Collection<Headway>; the set of observable GTUs in the current lane (can not be null and may include the gtu)
      rightLaneTraffic - 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)
      leftLaneTraffic - 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:
      GTUException - when the speed of the GTU can not be determined
      ParameterException - in case of a parameter problem.

    • getName

      public final String getName()
      Return the name of this GTU following model.
      Specified by:
      getName in interface LaneChangeModel
      Returns:
      String; just the name of the GTU following model

    • getLongName

      public final String getLongName()
      Return complete textual information about this instantiation of this GTU following model.
      Specified by:
      getLongName in interface LaneChangeModel
      Returns:
      String; the name and parameter values of the GTU following model

    • toString

      public final String toString()
      Overrides:
      toString in class Object
