Abstract

This study investigates the effects of varying levels of fatigue on cognitive functions during driving. Fatigue is a significant factor that can impair a driver's ability to perceive, process, and react to stimuli on the road, potentially leading to accidents. Through a series of experiments, participants were subjected to different levels of fatigue induced through sleep deprivation or extended driving sessions. Cognitive functions such as attention, reaction time, decisionmaking, and situational awareness were measured using standardized tests and driving simulations. Results indicate that as fatigue levels increase, there is a corresponding decline in cognitive performance, with drivers exhibiting slower reaction times, reduced attentional capacity, and impaired decision-making abilities. These findings underscore the importance of managing fatigue during driving and highlight the need for interventions to mitigate its detrimental effects on road safety.
