Abstract

Background: Evidence suggests that train drivers experience a high level of fatigue and mental workload. The present study aimed to assess overall, physical, and mental fatigue levels and their correlations with the mental workload in the metro train operation. Study Design: A cross-sectional study. Methods: This study was conducted on all 1194 train drivers in the Tehran Metro. The train drivers completed the Samn-Perelli Fatigue Scale and the Fatigue Assessment Scales at the beginning and end of the shift. In addition, they completed the National Aeronautics and Space Administration Task Load Index in the middle and at the end of the shift. Correlation and regression analyses were performed on the data to test the study hypothesis. Results: Overall, physical, and mental fatigue levels increased significantly at the end of the shift compared to the onset of the shift (P<0.001). The mental workload and related dimensions were significantly increased at the end of the shift compared to the middle of the shift (P<0.001). Mental demand was the most important workload problem among the train drivers. The highest correlation was found between overall workload and time pressure (R=0.68, P<0.001). Conclusion: The mental workload had a significant correlation with work fatigue in the train drivers. Control measures should be focused on the mental workload and related dimensions, especially mental demand and time pressure.
火车司机工作疲劳与精神负担的相关性:横断面研究
背景:有证据表明,列车司机的疲劳程度和脑力工作量都很高。本研究旨在评估地铁列车运行过程中的整体疲劳、身体疲劳和精神疲劳水平及其与脑力劳动负荷的相关性。研究设计:横断面研究。研究方法:横断面研究:本研究针对德黑兰地铁的全部 1194 名列车司机。列车司机在班次开始和结束时填写了萨姆-佩雷利疲劳量表和疲劳评估量表。此外,他们还在班中和班末填写了美国国家航空航天局任务负荷指数。对数据进行了相关和回归分析,以检验研究假设。结果显示总体而言,与轮班开始时相比,轮班结束时的身体和精神疲劳程度明显增加(P<0.001)。与轮班中期相比,轮班结束时的脑力工作量和相关维度明显增加(P<0.001)。精神需求是火车司机最主要的工作量问题。总体工作量与时间压力之间的相关性最高(R=0.68,P<0.001)。结论精神工作量与火车司机的工作疲劳有明显的相关性。控制措施应侧重于脑力工作量及相关维度,尤其是精神需求和时间压力。
