Implementation of a psychomotor vigilance test to investigate the effects of driving fatigue on oil and gas truck drivers’ performance

Abstract

IntroductionDriving 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.MethodsThus, 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.ResultsFor 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.DiscussionDuring 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.

A blueprint for a new commercial driving epidemiology: An emerging paradigm grounded in integrative exposome and network epistemologies

“…In a labor-intensive, time-constrained work environment, commercial drivers experience a plethora of interrelated strains, including excess levels of: (a) psychological pressures such as stress, isolation, and related burdens 15 amidst long and irregular workshifts (up to 14 consecutive hours a day and 70 hours in an 8-day span, when adhering to HOS rules) 16 and associated fatigue and sleep deprivation 17,18 ; (b) adverse physical, environmental, chemical, and noise exposures 19,20 ; (c) behavioral concerns such as sedentariness, limited physical activity, and ergonomic problems 21,22 ; and (d) work-life balance and home and family pressures. 23 Additionally, while on the road, commercial drivers are faced with limited affordable healthful food choices as well as access to quality and affordable healthcare services.…”
