【摘要】：随着我国社会经济高速稳步的发展，我国的公路建设发展迅猛，路网规模不断扩大，道路质量不断提高，而随之而来的道路交通事故数亦连年居高。道路交通安全问题的研究具有广泛的现实意义。本文通过对道路交通安全现状进行分析，运用灰色关联分析确定各类因素对交通事故的影响权重，权证了影响道路交通安全的主要因素为超速，进而针对性的对我国道路安全现状进行分析，明确了易发生超速现象的情况以及超速行驶对于驾驶员的影响；应用自解释道路理念，从理念的机制加以分析和理解,找出了我国目前道路安全性建设的状况，提出了自解释道路理念与我国道路设计相结合的基本要点；运用VISSIM仿真软件对京新高速胶泥湾至冀晋界K26+000至K43+900路段的交通安全性进行了模拟仿真，根据评价结果发现了我国传统道路设计模式存在的不足；运用自解释道路理念加以优化，并再次利用VISSIM软件对优化方案进行模拟仿真，，评价结果显示出运用自解释道路理念对道路进行优化对于交通安全有很大的提升。论文从速度控制的角度对道路的安全性进行了研究与探索，运用灰色关联分析和VISSIM仿真软件对道路进行评价是本文主要内容，将自解释道路的理念引入优化设计具有创新性，为今后的道路行车安全性的研究提供了新的视角，对于提升我国道路的宽容性具有现实意义。
[Abstract]:With the rapid and steady development of our country's social economy, the highway construction in our country is developing rapidly, the scale of road network is expanding, the quality of road is improving, and the number of road traffic accidents has been high year after year. The study of road traffic safety has extensive practical significance. Based on the analysis of the present situation of road traffic safety and the grey correlation analysis, this paper determines the weight of the influence of various factors on traffic accidents. The authority card shows that the main factor affecting road traffic safety is speeding. Furthermore, the paper analyzes the current situation of road safety in China, clarifies the situation of overspeed and the influence of speeding on drivers, and analyzes and understands it from the mechanism of self-explanation of road. This paper finds out the current situation of road safety construction in our country, and puts forward the basic points of combining the self-explanation road concept with the road design in our country. The traffic safety between K26000 and K43,900 of Jingxin high-speed cement bay to Jishin was simulated by using VISSIM software. According to the evaluation results, the shortcomings of the traditional road design mode in China were found. Using the idea of self-explanatory road to optimize, and again using VISSIM software to simulate the optimization scheme, the evaluation results show that the use of self-explanatory road concept to optimize the road has a great improvement on traffic safety. The paper studies and explores the safety of road from the angle of speed control. The use of grey correlation analysis and VISSIM simulation software to evaluate the road is the main content of this paper. It is innovative to introduce the concept of self-explaining road into the optimization design. It provides a new angle of view for the study of road traffic safety in the future and has practical significance for improving the tolerance of roads in our country.
