目的:探讨模拟驾驶前后驾驶员脑力疲劳的主观评定和注意特征变化。方法:测量和比较16名健康男性白班出租车驾驶员在实验室条件下连续模拟驾驶6小时前后的主观疲劳感的差异和注意特征的变化,并以同一批驾驶员在休息日的同时段测量结果作为对照。结果:实验组和对照组疲劳前后在主观量表上的得分均无显著性差异。但在对注意特征的行为学测试中,实验组疲劳前后的结果差异显著,而对照组差异不显著。结论:在实验室条件下,驾驶员在模拟驾驶后虽然没有主观疲劳感,但注意的各个方面均受到不同程度的影响,呈下降的趋势。
Objective: To explore the subjective assessment of driver’s mental fatigue before and after simulated driving and the change of attentional characteristics. Methods: Sixteen healthy male shift taxi drivers measured and compared subjective fatigue changes and attention characteristics before and after driving six hours continuously under laboratory conditions, and measured the same batch of pilots on the same day of rest day Results as a control. Results: There was no significant difference in subjective scores between the experimental group and the control group before and after fatigue. However, in behavioral tests of attentional characteristics, the results of the experimental group before and after fatigue were significantly different, while the differences of the control group were not significant. Conclusion: Under laboratory conditions, the driver has no subjective feeling of fatigue after simulated driving. However, all aspects of attention are affected by different degrees, showing a downward trend.
