Applicability Evaluation And Optimize Technology Of Expressway Safety Facilities

Along with our country of social economy strength unceasing enhancement, each kind of infrastructure obtained the considerable development, in which had taken the traffic circulation foundation the highway facilities were the widespread development construction, these appeared unceasingly the highway for between economical intercourse, social resources transportation journey, the local sharing has provided a security, comfortably, highly effective, the quick channel. For the effective display highway function, the safeguard highway traffic safety, protect the highway user’s life and property safety, needs to carry on the enhancement and the optimization to the path safety equipment.Based on field research, and a large number of resources on the basis of induction, deduction, numerical simulation methods such as people, vehicles, roads, environmental and other aspects of the northwest mountain area expressway traffic accidents occurred during the feature, secure infrastructure and traffic problems and defects, and systematic study of the relationship between traffic safety and traffic safety facilities. With the influence factors on the basis of the identified road infrastructure safety, through hierarchy against the northwest expressway traffic safety and security facilities to evaluate the applicability so as to establish safety evaluation index system of expressway in mountain area. Finally, a mountain highway in northwest, for example, to evaluate the applicability of the different security facilities, and designs of safety facilities and safety technology. The research and exploration of traffic safety facilities of expressway in the future design, management, maintenance and renovation to provide basis for prolonging service life of highway, the strengthening of mountain highway safety, reducing accidents and has a very important meaning.
