Development of a strategy model of the driver

Based upon vehicle constraints and known human operator characteristics, a class of strategy models was postulated for describing driver behavior in the lane-keeping task, To verify the appropriateness of this class of models, 10 student subjects were chosen to be modeled. Each subject performed the lane-keeping task in a highway driving simulator for five minutes. Each subject's time histories of steering, lateral position, and yaw angle provided a basis for estimating the driver parameters necessary to specify an appropriate model of the subject. Ten driver models were then programmed to describe the 10 subjects, respectively. Each model was run over the same course, and experienced the same conditions as its corresponding subject. Regression analysis provided a means of comparing subject and model responses. The models developed were found to be effective in describing the responses of the 10 subjects, respectively.
