In our vehicle driving, it is important to take appropriate evasive action based on the recognition of the hazardous event as one of driver's ability. However, there are few researches about association of drivers' knowledge and avoidance ability in the previously. In this study, "Hazard sensitivity" which means the driver's ability included both of knowledge of the hazardous event and avoidance ability has been proposed to evaluate driving safety. And in this paper, an analysis method for it through the quantification of driver's knowledge and avoidance behavior is constructed. In order to obtain the knowledge and avoidance ability the experiments with subject driver were designed and conducted. By using obtained data, validation for proposed analysis method was also carried out. As a result of correlated with driving tendency, classification possibility of hazard sensitivity based on the individual characteristics had been confirmed.
