The human operator behavior, in backward lane-changemaneuver of a tractor-trailer combination, is clarified through field experiments and mathematical simulation. A human operator cognition model and a kinematic vehicle model proposed earlier, are utilized in the investigation. The operator behavior is analyzed through multi-stage computer simulation. The number of stages necessary for a complete backward maneuver, is found to be more than that for a forward maneuver. The driving techniques of a skillful operator and a good one, as well as the differences between the two, are also elucidated through multi-stage simulation. The closed-loop characteristics obtained here are applicable to the automatic steering problem of articulated vehicles.
