Abstract
This paper tried to reproduce driver’s manipulation which varies depends on driver’s intention. For simulate driver’s control, the driver model is usually used. Though, commonly used driver model, like look-ahead model, sets up its characteristics for operation under certain driving tasks beforehand. Under the hypothesis that driver deliberately select the terminal vehicle movement so that his or her dexterity of driving is represented the degree of terminal set, nonlinear optimization technique is employed. Lane change simulation shows the order of terminal condition fixes vehicle path. Experiment supports the hypothesis on this case to some degree.
