摘要

本研究从睡眠债务的角度模拟了部分睡眠剥夺(PSD)对平均速度、速度变异性和相关撞车概率的影响。50名男性驾驶员在连续1晚和2晚PSD(睡眠≤4.5h;使用Actiwatch测量)和不剥夺睡眠的TS3。TS1、TS2和TS3的平均睡眠债分别为2.2 h、1.53 h和无睡眠债。一个广义线性混合模型(GLMM)模型结果表明，随着睡眠债务的增加，撞车风险增加1.5倍，随着速度的增加，撞车风险增加27%，随着速度变异性的增加，撞车风险增加一倍。研究结果表明，将车速降低15%以上就可以消除撞车的风险。然而，司机在睡眠不足的情况下失去了对速度的控制。

Effects of partial sleep deprivation: speed management ability and associated crash risk

ABSTRACT This study modelled the effects of partial sleep deprivation (PSD) in terms of sleep debt on mean speed, speed variability and associated crash probability. Fifty male drivers drove the driving simulator in three test sessions (TS): TS1 (night) and TS2 (lunch) after one and two consecutive nights of PSD (sleep ≤4.5h; measured using Actiwatch), respectively and TS3 with no sleep deprivation. The mean sleep debt observed in TS1, TS2 and TS3 were 2.2 h, 1.53 h and no sleep debt, respectively. A generalized linear mixed model (GLMM) model results showed that the crash risk increased 1.5 times with increasing sleep debt, 27% with increasing speed and doubled with increasing speed-variability. The findings show that reducing speed by more than 15% could have eliminated the risk of crashes. However, the drivers suffered from loss of speed control under the sleep debt conditions.

期刊介绍： Transportation Letters: The International Journal of Transportation Research is a quarterly journal that publishes high-quality peer-reviewed and mini-review papers as well as technical notes and book reviews on the state-of-the-art in transportation research. The focus of Transportation Letters is on analytical and empirical findings, methodological papers, and theoretical and conceptual insights across all areas of research. Review resource papers that merge descriptions of the state-of-the-art with innovative and new methodological, theoretical, and conceptual insights spanning all areas of transportation research are invited and of particular interest.
