【摘要】：隨著我國高速公路的飛速發(fā)展，高速公路的交通安全問題日益成為亟需解決的難題，高速公路交通事故后果嚴重，損失巨大，難以處理的顯著特點，特別是，由于降雨，路況更加復雜，從而更容易造成交通事故的發(fā)生，對人民財產安全造成了極大的安全隱患。由于我國高速公路起步較晚，還缺乏對其的相關認識和研究，尤其是在降雨狀況下的高速公路交通安全的研究更有待提升。 本文在總結分析國內外關于降雨天氣下的高速公路交通安全運營生產的基礎上對降雨條件下高速公路公路交通事故的特點進行分析，結合相關的數(shù)據(jù)資料，分析得出降雨天氣下的高速公路安全行車機理，并以此為基礎確定降雨天氣時高速公路安全行駛的車速條件。 通過專家調查法以及累積比數(shù)logit模型這兩種方法從單因素影響以及發(fā)生概率出發(fā)，對高速公路的交通事故風險進行評估。提出在不同的降雨等級狀況下，汽車在高速公路行駛的理想最高時速。在處理應急狀況時，通過層次分析法，根據(jù)列出的可能的各個應急問題的影響范圍和可能造成的交通事故的嚴重程度等指標進行排序，，從中找出高速公路在應急管理中所迫切需要解決的問題。對于各個部門的應急管理能力，提出了相應的打分標準，對各個職能部門的管理能力進行評價，并對不足之處提出改進建議和行之有效的措施。
[Abstract]:With the rapid development of expressway in our country, the problem of highway traffic safety has become a difficult problem to be solved day by day. The consequence of expressway traffic accident is serious, the loss is huge, and it is difficult to deal with, especially, because of rainfall, The road condition is more complex, thus causing traffic accidents more easily, and causing great hidden danger to people's property safety. Due to the late start of expressway in China, there is still a lack of related knowledge and research on it, especially the study of highway traffic safety under the condition of rainfall needs to be improved. On the basis of summing up and analyzing the operation and production of expressway traffic safety under rainfall weather at home and abroad, this paper analyzes the characteristics of expressway traffic accidents under rainfall conditions, and combines relevant data. The safe driving mechanism of freeway under rainfall weather is analyzed, and the speed conditions of safe driving of expressway under rainfall weather are determined on the basis of the analysis. Through expert investigation and cumulative ratio logit model, the traffic accident risk of expressway is evaluated from single factor and probability of occurrence. Under different rainfall levels, the ideal maximum speed of the vehicle on the highway is put forward. In dealing with the emergency situation, the Analytic hierarchy process (AHP) is used to rank the impact of possible emergency problems and the severity of possible traffic accidents. Find out the problems that need to be solved urgently in the emergency management of expressway. For the emergency management ability of each department, the corresponding scoring standard is put forward, the management ability of each functional department is evaluated, and the improvement suggestions and effective measures are put forward.
