Research On Driver Fatigue

Driver fatigue endangers traffic safety increasingly. According to the analysis of traffic incidents causation, 49% of the incidents are due to driver fatigue. Driving is mainly composed of perception and information processing. Driver fatigue is the representation of physiological change. The deterioration of driving ability owing to these factors leads to driver fault. Consequently, the study of driver fatigue is fairly important to preventing traffic incidents.The thesis specializes driver fatigue wholly, including sense fatigue, estimate fatigue, operation fatigue. Driver fatigue is subdivided into the fatigue of vision, audition, estimate, operation, and worsen of reaction, notice. The paper also deals with driver fatigue in some given conditions. The testing technology of driver fatigue is discussed and applied.According to the analysis and testing of driver fatigue, it can be found that driver's behavior deteriorates generally. That is, vision, audition and estimate are all debased. Further, driver's reaction time is prolonged and operation failure is increased.
