Highway Tunnel Safety Evaluation System And Security Technology Research

In China since 1990 s,the development of the economy by leaps and bounds,transport business is booming,especially highway construction and management have made great progress,especially in the mountainous areas in China,more and more highways,highway through the tunnel of more and more,he tunnel traffic accidents is high,especially in the entrance to a tunnel,not only high accidents,the number of accident severity is bigger,how to reduce the grew up highway tunnel traffic accidents,improve tunnel traffic safety becomes an important research subject.Grew up in the tunnel sections safety evaluation,found that the accident black spots,improve safety measures to improve the tunnel traffic safety plays an important role.This article is based on our country highway tunnel traffic accidents were analyzed,and the use ofmechanism and mathematical statistics methods to analyze the cause of the accident,clear distribution characteristics of space and time tunnel traffic accident,accident safety evaluation model is set up,improvement Suggestions are put forward in view of the influence factors:(1)in the road traffic accident black point identification methods at home and abroad were reviewed on the basis of combing the advantages and disadvantages of the traditional methods and applicable conditions are analyzed,in jiangxi expressway buddhist accidents starting point to identify the tunnel as an example,the application of accidents,accident rate,respectively,to identify the position of accident black point,analyzing its causes should be combined with the traffic road environment.(2)propose the adverse weather conditions of mountain area highway speed limit standard,consider driver characteristics,road conditions,weather conditions,such as to determine a reasonable driving speed.(3)based on the theory of domestic and foreign research,in jiangxi,fozi mountain tunnel of highway as the research object,through the use of advanced computer communication technology to build tunnels safety early warning system,for managers,the driver to provide important data.
