During the subjective evaluation of sleepiness, simoultenius measurements of seat vibrations and physilosical values such as heart beat rate and brain waves were conducted. After the experiment, the relations between the sleepiness and physical and physiolosical metrics were tested for the sleepiness model. As a resut, positive contributions of physilogical values and negtive contribution of seat vibration were observed for sleepiness.", }
