  • Constructor Details

    • IDM

      public IDM()
      Default constructor using default models for desired headway and desired speed.

    • IDM

      public IDM​(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 Details

    • getName

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

    • getLongName

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

    • combineInteractionTerm

      protected final Acceleration combineInteractionTerm​(Acceleration aFree, Parameters parameters, Speed speed, Speed desiredSpeed, Length desiredHeadway, PerceptionIterable<? extends Headway> leaders) 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.
      parameters - Parameters; Parameters.
      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.
