This paper extracted index parameters to estimate the state of drivers. This study is based on a hypothesis that the risk of traffic accidents becomes higher when drivers are in deviant states. We chose the index parameters by comparing the driver's act with his/her typical driving data stocked in a driving database. Specifically, we used the minimum speed in an mtersection with a stop sign and the frequency distribution of braking deceleration in order to pick out the driving data including the drive?s deviant state. Additionally, by analing these data, we found that the transition of the driveis state is present in the speed when cruising alone, and time-headway when following a preceding vehicle.
