Indices for characterizing driving style and their relevance to car following behavior

In driver support system studies, it is concerned that mismatch between driver and machine may occur. One of the methods for its solution is to understand driver\´s behavior, which may be affected by driving style as driver\´s individual characteristic. In this study, "Driving Style Questionnaire" (DSQ) which had 8 scales was developed from a questionnaire survey and principal component analysis. Then, through an application to analysis of car following behavior at low speed, validity of the DSQ was examined by correlation analysis with behavioral indices and its usefulness was shown from modeling approach. The DSQ will contribute to characterizing drivers.
