Analysis of driving fatigue factors and mechanism based on safety drgonomics

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