| Abstract: | Driving in a monotonous environment, such as a highway, facilitates a phenomenon known as driver fatigue which has been linked to the cause of many road accidents in Europe. Driver fatigue creates a possibility for accidents to occur due to vigilance decrement. In this study, an experiment was designed to investigate the ability of EEG to predict sleepiness and changes in driving performances. Alpha power and theta power were derived from the EEG, sleepiness was assessed using the Karolinska Sleepiness Scale and driving performance was assessed by determining steering errors and instruction misses. Multi-level model analyses were employed to explore the relations between the aforementioned variables. The results showed that alpha and theta power are related to sleepiness. Changes in alpha power was related to changes in instruction misses, though theta power was not related to instruction miss. Both alpha and theta power were not related to changes in steering errors. It can therefore be concluded that it is possible to monitor vigilant state using the EEG through observing levels of sleepiness and instruction misses. |
