摘要
驾驶员疲劳是指驾驶员在驾驶过程中,身体机能整体性的下降现象,它是导致交通事故的主要因素之一。因此,选取一种有效可靠的生理指标检测驾驶员的工作疲劳具有重要的实践意义。本研究采用驾驶员动态危险知觉视频量表加载工作负荷,诱发疲劳。使用自我报告法、眼动追踪与心电技术,测查39名驾驶员的疲劳状态。结果显示:采用瞳孔直径指标检测驾驶疲劳具有跨人群的一致性,随着驾驶员自我报告的困倦感增加,其瞳孔直径缩小,心率变异性减小,瞳孔直径与心率变异性呈显著正相关。说明随着工作时间的延长,驾驶员逐渐进入疲劳状态,瞳孔直径可以成为检测驾驶员心理疲劳的有效指标。
Driver fatigue is the integrity of physical function decline phenomenon during driving process . Driver fatigue is one of the primary factors inducing accidents .So how to select an effective and reliable physiological indicator to detect driver fatigue has important practical significance .The workload was elici-ted by driver dynamic hazard perception video scale to induce fatigue .This study measured 39 drivers’ fa-tigue state by using self-report ,eye tracking and ECG technology .The results show that using the pupil diameter indicators detect driver fatigue with cross crowd consistency .And with the extended working hours ,the driver’s self-reported sleepiness increased ,pupil diameter narrowing ,heart rate variability re-ducing ,pupil diameter and heart rate variability were positively correlated .This indicates that with pro-longed working hours ,the driver gradually becomes fatigue .The result implied that the pupil diameter can effectively measure the driver fatigue .
