Concerning to active safety in traffic situations, adaptive driving support systems for operational ability of individual driver are necessary for prevention of traffic accidents. Driving ability depends on driver's internal factors such as mental tension. The aim of this study is to develop an estimation system of driver's state of tension. In order to estimate driver's state in real time, we examined steering operation (v) and head motion (Gz) of a driver as adaptive indices of tension for individuals. It was confirmed that v and Gz were complementary indices for each other, and both v and Gz correlated with reaction time of a driver during driving conducted using a simple driving simulator.
