The extent to which sleepy drivers are aware of sleepiness has implications for the prevention of sleep-related crashes, especially for drivers younger than 30 years old who are most at risk. Using a real car interactive simulator, we report on EEG, subjective sleepiness, and lane drifting (sleepiness-related driving impairment) from 38 sleep-restricted, healthy young adults undergoing nontreatment control conditions from three (unpublished) investigations using the same experimental protocols for assessing various drinks intended to alleviate sleepiness. Participants drove 2 h during midafternoon under monotonous conditions. For all studies, subjective sleepiness and EEG activity indicative of sleepiness were highly correlated, with both changing concomitantly, along with lane drifting. Drivers had knowledge of their physiological sleepiness. There were indications that sugar content of these drinks may additionally affect sleepiness.
困倦驾驶员对自身困倦的认知程度对预防与睡眠相关的撞车事故具有重要意义，尤其是对于风险最高的30岁以下驾驶员。通过使用真实汽车交互模拟器，我们报告了38名睡眠受限的健康年轻成年人在三项（未发表的）研究中处于非治疗对照条件下的脑电图（EEG）、主观困倦感和车道偏移（与困倦相关的驾驶能力受损）情况，这些研究采用相同的实验方案来评估各种旨在缓解困倦的饮品。参与者在午后时段单调的条件下驾驶2小时。在所有研究中，主观困倦感和表明困倦的脑电图活动高度相关，两者同时变化，同时伴有车道偏移。驾驶员了解自己的生理困倦状况。有迹象表明，这些饮品的糖分含量可能会额外影响困倦感。
