Influence of Highway Alignment Design Factors on Traffic Safety

The safety is the initial factor that highway design needs to be considered,and improving alignment design is the most valid to advance driving safety.Good alignment design is the root that promises to guarantee driving safety.At the very start,the highway design should value the alignment safety design.From the highway align- ment (straight line,plane curve,vertical curve,alignment combination etc.),the stadia,and the alignment combina- tion and road view,the paper analyzed the influence of highway alignment design factors on traffic safety,and put forward some problems that should be noticed in alignment design,in order to make highway alignment suit the request of the pilot's vision sense and mental state,and assurance traffic safety furthest.What mentioned in the text has certain instruction meaning to the high- way design department and the related design personnel.
