                                             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.
