【摘要】：近年来，随着我国高速公路的快速发展，交通事故也在不断增加。高速公路连续长下坡路段特大交通事故时有发生，己经引起了社会各界的广泛关注。为了提高高速公路连续长下坡路段交通安全状况，分析交通事故的机理，合理设置系统的交通安全设施，形成科学完整的交通安全保障体系是最现实、最有效地措施。论文在搜集相关资料和研宄文献的基础上，，对高速公路连续长下坡路段安全性进行分析，指出驾驶员、车辆、道路条件和交通环境对交通事故的影响。探讨交通事故发生的成因及机理，找出目前高速公路连续长下坡路段安全设施存在的问题。结合高速公路连续长下坡路段驾驶员、车辆、道路条件和交通环境等特性，提出高速公路连续长下坡路段安全设施设置技术的总体设计思路。通过分析高速公路连续长下坡路段上安全设施与交通事故次数之间的关系，建立了高速公路连续长下坡路段安全设施的安全保障度模型。根据高速公路连续长下坡路段安全设施设置总体设计思路，确定包括交通标志标线设计、几何线形设计、减速护栏设计、管理与服务设施设计、避险车道设计等内容的设计标准。同时，建立了高速公路连续长下坡路段安全设施系统评价模型，作为氋速公路连续长下坡路段交通安全设施设置技术标准及安全预警依据。针对沪渝高速石柱至冷水段连续长下坡安全保障工程设施的设计，做出具体的交通安全设施保障措施，以期降低交通事故的发生率。本文的研究最大限度的发挥高速公路连续长下坡路段交通安全设施的功能，保障高速公路连续长下坡路段安全平稳行车，推动高速公路连续长下坡路段交通安全状况的改善，具有十分重要的理论和现实意义。
[Abstract]:In recent years, with the rapid development of highway in China, traffic accidents are also increasing. Serious traffic accidents occur frequently in long downhill section of expressway, which has attracted wide attention from all walks of life. In order to improve the traffic safety condition of continuous downhill section of expressway, analyze the mechanism of traffic accident, reasonably set up systematic traffic safety facilities, and form a scientific and complete traffic safety guarantee system is the most realistic and effective measure. On the basis of collecting relevant data and researching literature, the paper analyzes the safety of continuous downhill section of expressway, and points out the influence of driver, vehicle, road condition and traffic environment on traffic accident. This paper probes into the causes and mechanism of traffic accidents and finds out the problems existing in the safety facilities of the continuous downhill section of the expressway at present. Combined with the characteristics of drivers, vehicles, road conditions and traffic environment of continuous long downhill section of expressway, the overall design idea of setting up safety facilities for continuous downhill section of expressway is put forward. Based on the analysis of the relationship between the safety facilities and the number of traffic accidents on the continuous downhill section of the expressway, the safety guarantee degree model of the safety facilities in the continuous downhill section of the expressway is established. According to the overall design idea of setting safety facilities in continuous long downhill section of expressway, it is determined to include traffic sign marking design, geometric alignment design, deceleration guardrail design, management and service facility design, The design standard of the content such as the design of the safe haven lane. At the same time, a systematic evaluation model of safety facilities in continuous downhill section of expressway is established, which can be used as the technical standard of setting up traffic safety facilities and the basis of safety warning for continuous downhill section of highway with high speed. Aiming at the design of the safety and security engineering facilities of the continuous downhill slope in the section between stone columns and cold water of the Shanghai-Chongqing Expressway, concrete measures are made to ensure the traffic safety facilities in order to reduce the incidence of traffic accidents. The research in this paper maximizes the function of the traffic safety facilities in the continuous downhill section of the expressway, ensures the safe and steady driving of the continuous long downhill section of the expressway, and promotes the improvement of the traffic safety condition of the continuous long downhill section of the expressway. It has very important theoretical and practical significance.
