Analysis of Driving Fatigue Factors and Mechanism Based on Safety Ergonomics

Nowadays, the traffic accident occupies the most scale among all the fatal accidents. Driving fatigue has become the main factor which caused traffic accidents. But driving fatigue, formed by complex reasons, such as traffic marks, environment, drivers themselves and so on, and interactive factors, shows the multiple dimensionality and the multiple profile characters. Based on safety ergonomics principle, the paper analyzes these interactive factors, induces three processing phases: perception, judging and acting, concludes the behavior mode of driving fatigue and analyzes the mechanism, which is very important on theory and practice to prevent driving fatigue and ensure vehicle safety.
