Abstract
This paper is concerned with a quantitative classification based on driver characteristics of steering maneuvers. The evaluation indexes that can be used for quantifying differences of driver groups such as experimental driver or beginner driver are proposed. The crank course test using actual car is performed in order to find the evaluation indexes to classify the driver's steering maneuvers. Then the crank course test using driving simulator is performed when gear ratio and a course width are changed. The characteristics of driver's steering maneuvers using these indexes are classified. It is demonstrated in this investigation that the method can be effectively used for classify an important characteristics of driver's steering maneuvers.
