Driving fatigue has been shown to increase the risk of accidents and potentially fatal crashes. Fatigue is a serious risk that some drivers do not take seriously. Previous studies investigated the effects of driving fatigue in the Malaysian oil and gas transportation industry by employing survey questionnaires. However, they did not explain the behavior of fatigue. Besides, these results required validation by a more reliable method that can describe how fatigue occurs.
Thus, in this study, we used the Psychomotor Vigilance Test (PVT-192) and a short survey to address driving fatigue behavior and identify the influences of driving fatigue on driving performance in real life (on the road) with actual oil and gas tanker drivers. The total participants in the experimental study were 58 drivers.
For the analysis, a Wilcoxon Signed Ranks Test, Z value and Spearman's rho were used to measure the significant difference between the pre and post-tests of PVT and the correlation between the fatigue variables and driving performance.
During the experiment's first and second days, this study's results indicated that driving fatigue gradually escalated. Likewise, there was a negative correlation based on the test of the relationship between the PVT data and the driving performance survey data. Additionally, the drivers suffer from accumulative fatigue, which requires more effort from the transportation company management to promote the drivers awareness of fatigue consequences.
驾驶疲劳已被证明会增加事故和潜在致命事故的风险。疲劳是一些司机没有认真对待的严重风险。先前的研究通过使用问卷调查调查了马来西亚石油和天然气运输行业中驾驶疲劳的影响。然而,他们没有解释疲劳的行为。此外,这些结果需要通过一种更可靠的方法来验证,这种方法可以描述疲劳是如何发生的。
因此,在这项研究中,我们使用了精神运动警觉测试(PVT-192)和一个简短的调查来解决驾驶疲劳行为,并在现实生活中(在路上)用实际的石油和天然气罐车司机识别驾驶疲劳对驾驶性能的影响。实验研究的总参与者为 58 名司机。
对于分析,使用 Wilcoxon 符号秩检验、Z 值和 Spearman's rho 来测量 PVT 前后测试之间的显著差异以及疲劳变量与驾驶性能之间的相关性。
在实验的第一和第二天,本研究的结果表明驾驶疲劳逐渐加剧。同样,根据 PVT 数据与驾驶性能调查数据之间的关系测试,存在负相关。此外,司机们会受到累积性疲劳的影响,这需要运输公司管理层付出更多努力,提高司机对疲劳后果的认识。
