Driver Sleepiness Assessed by Electroencephalography - Different Methods Applied to One Single Data Set

---

Abstract

An overview of several methods of electroencephalography (EEG) analysis in order to assess driver sleepiness is presented. All methods were applied to one single data set obtained from overnight driving simulations in our lab. 10 young adults (age 22.4 ± 4.1 years) participated and drove on rural roads; time on task was 7 x 40 min and time since sleep ranged between 16 and 22 hours. Results show large inter-individual variability of all variables and moderate correlation coefficients to one subjective and one objective independent variable of driver drowsiness. Only one method, the detection of microsleep-like EEG patterns, provides a variable with strong increases immediately before sleepiness related crashes. It is concluded that EEG analysis should attach more importance to shortterm patterns and should renounce the analysis of spectral power in four bands.
