Accidents caused by driver’s drowsiness behind the steering wheel have a high fatality rate because of the marked decline in the driver’s abilities of perception, recognition and vehicle control abilities while sleepy. Preventing accidents caused by drowsiness behind the steering wheel is highly desirable but requires techniques for continuously estimating driver’s abilities of perception, recognition and vehicle control abilities; this study proposes methods for drowsiness estimation that combine the Electroencephalogram (EEG) log sub band power spectrum, correlation analysis, principal component analysis, Autoregressive (AR) Model and Liner Regression Models to indirectly estimate driver’s drowsiness level in a virtual-reality-based driving simulator. Results show that it is feasible to quantitatively monitor driver’s alertness with concurrent changes in driving performance in a realistic driving simulator.
