驾驶员疲劳仍然是全世界机动车事故的一个重要原因。人们越来越多地利用新技术来提高道路安全，但没有有效的道路疲劳措施。虽然模拟驾驶任务是敏感的，简单的性能任务已被用于工业疲劳管理系统（FMS），以量化风险，很少有人知道这些措施之间的关系。建立一种简单的道路疲劳测量方法，作为驾驶健康工具，对于道路安全和事故预防来说是一个重要问题，特别是因为许多与疲劳相关的事故是可以预防的。本研究旨在测量疲劳相关的性能递减使用一个简单的任务（反应时间- RT）和一个复杂的任务（驾驶模拟），并确定这些措施之间的联系的潜力，从而提高FMS的成功。15名志愿者参与者（7男，8女），年龄22-56岁（平均33.6岁），在8小时恢复睡眠机会之前进行26小时的监督觉醒。参与者接受了30分钟的交互式驾驶模拟测试，并在清醒4、8、18和24小时以及恢复睡眠后进行了10分钟的精神运动警惕任务（PVT）。长时间的清醒导致PVT和驾驶性能显著下降。虽然这些措施显然是相互关联的，我们的分析表明，驾驶模拟不能取代一个简单的PVT。需要进一步的研究，密切研究性能指标之间的联系，并促进准确的管理健身驱动器，这需要更复杂的性能评估比RT单独。(C)2007爱思唯尔有限公司保留所有权利。
Driver fatigue remains a significant cause of motor-vehicle accidents worldwide. New technologies are increasingly utilised to improve road safety, but there are no effective on-road measures for fatigue. While simulated driving tasks are sensitive, and simple performance tasks have been used in industrial fatigue management systems (FMS) to quantify risk, little is known about the relationship between such measures. Establishing a simple, on-road measure of fatigue, as a fitness-to-drive tool, is an important issue for road safety and accident prevention, particularly as many fatigue related accidents are preventable. This study aimed to measure fatigue-related performance decrements using a simple task (reaction time - RT) and a complex task (driving simulation), and to determine the potential for a link between such measures, thus improving FMS success. Fifteen volunteer participants (7 m, 8 f) aged 22-56 years (mean 33.6 years), underwent 26 h of supervised wakefulness before an 8 h recovery sleep opportunity. Participants were tested using a 30-min interactive driving simulation test, bracketed by a 10-min psychomotor vigilance task (PVT) at 4, 8, 18 and 24 h of wakefulness, and following recovery sleep. Extended wakefulness caused significant decrements in PVT and driving performance. Although these measures are clearly linked, our analyses suggest that driving simulation cannot be replaced by a simple PVT. Further research is needed to closely examine links between performance measures, and to facilitate accurate management of fitness to drive, which requires more complex assessments of performance than RT alone.
