Abstract

Driver fatigue is a multidimensional and complex subject, addressed in past years by many researchers but not completely defined and clarified: terms like drowsiness, sleepiness and fatigue are often used like synonymous. The importance of studying fatigue is related to the fact that it represents a contributing factor in many crashes every year. Following a sub categorization of fatigue concept recently proposed by May and Baldwin (2009) this paper focuses on the analysis of passive task-related (TR) effects of highway driving in monotonous environments. The analysis proposed in this paper was based on results obtained using a driving simulator approach, which has been widely adopted in recent years for this kind of studies, given the opportunity to analyze risky driving conditions in a safe and controlled environment. Differently from previous studies, this paper analyzes the effects of monotonous environment separating its effects from other causal factors of fatigued state, aiming at a better evaluation of their relative importance and of the onset of driving fatigue phenomenon. Mixed-effects models were chosen as suitable analysis tool to deal with the objectives of this study.
