Assessment of Fatigue through Working Environment and Hazardous Driving Behavior among Drivers

Abstract

There are scientific studies about Fatigue that leads to decrease in driving performance displaying inattentive and slower reaction time. The review of the literature has provided factors which can influence the onset of fatigue: sleep factors, work factors and health factors which is a major safety hazard to drivers. The research study applied Structural Equation Modeling (SEM) to analyze the interrelationship among driving hours (DH), sleep duration (SD), type of driver (TOD), experience, violations, type of route (TR), comfortability on car controls (CC), traffic density (TD), weather, habit, stress, personality, and fatigue simultaneously. Fatigue is additionally measured by Driver Fatigue Assessment Scale which the researchers have made based on Fatigue Assessment Scale (FAS) and Fatigue Severity Scale (FSS). 254 respondents answered the online survey form conducted by the researchers with 31 questions in total designed to assess fatigue through working environment and hazardous driving among drivers. At the end of the survey, Driver Fatigue Assessment Scale is added to be ranked by 1-5 which is never to always on how frequent they experience the fatigue based on the questions given. The results showed that experience had significant direct effect on DH, TOD was found had significant direct effect on CC, and habit was also found had significant direct effects on personality and stress. In addition, TOD was also found to be a good predictor to CC. The findings suggest that higher value of habit achieved, the higher probability to have stress while the lower value of stress achieved, the lower probability to have fatigue among drivers.
