【摘要】：随着我国社会经济实力的不断增强,各类基础设施得到了长足的发展,其中作为交通运行基础的公路设施更是广泛的开展建设,这些不断出现的高速公路为人民的交通出行、地区间的经济往来、社会资源的共享提供了一条安全、舒适、高效、快捷的通道。交通安全设施主要包括标志标线、护栏、视线诱导设施及信息管理设备等,是高速公路安全运营的的硬件保障。高速公路受地质地形等原因的制约,行车安全具有较大的风险性,因此需特别重视交通安全设施的适用性。为了能够有效的发挥高速公路的功能,保障高速公路的交通安全,保护高速公路使用者的生命财产安全,需要对道路的安全设施进行重视和优化。在现场调研及查阅大量参考资料的基础上采用归纳法、演绎法、数值仿真实验等方法,从人员、车辆、道路、环境等方面分析了青海省高速公路运营期间交通事故的特征及产生交通事故的原因,并分析安全设施的适用性应用现状,系统研究了交通安全设施与交通安全事故之间的相互关系。在确定道路设施安全性影响因素的基础上,通过逐一层次分解分析法对西北某高速公路交通安全状况及安全设施适用性进行评价,从而建立高速公路安全设施适应性评价指标体系。以西北地区青海省高速公路为例,分析该省高速公路路段交通事故产生特点及原因及其差异性,因而对不同安全设施的适用性进行评价,并提出交通安全设施改善与保障技术研究。研发了一直实用新型的柔性桥梁缓冲消能型的防撞装置,对保障桥梁结构、行车安全与舒适性均有较大的改善。并具体到青海省茶格高速公路安全设施存在的问题提出了相应的优化措施,以提供该高速公路的运营安全性。研究结论对面向高速公路交通安全运营的交通设施设计、管理、维护与改造提供理论依据,对延长高速公路使用寿命、加强山区高速公路运行安全、减少事故发生等都具有十分重要的意义。
[Abstract]:With the increasing social and economic strength of our country, various kinds of infrastructure have been greatly developed, among which the highway facilities, which are the basis of traffic operation, have been widely built. Regional economic exchanges and social resource sharing provide a safe, comfortable, efficient and fast channel. Traffic safety facilities mainly include marking, guardrail, line of sight guidance facilities and information management equipment, which is the hardware guarantee of highway safety operation. The highway is restricted by geological terrain and other reasons, so the traffic safety has great risk, so it is necessary to pay special attention to the applicability of traffic safety facilities. In order to give full play to the function of expressway, ensure the traffic safety of expressway and protect the safety of life and property of expressway users, it is necessary to pay attention to and optimize the road safety facilities. On the basis of on-the-spot investigation and consulting a large number of reference materials, induction, deductive method, numerical simulation experiment and other methods are adopted, from personnel, vehicles, roads, etc. This paper analyzes the characteristics of traffic accidents and the causes of traffic accidents during the operation of Qinghai Expressway from the aspects of environment, and analyzes the current situation of the applicability of safety facilities. The relationship between traffic safety facilities and traffic safety accidents is systematically studied. On the basis of determining the factors affecting the safety of road facilities, the traffic safety situation and the applicability of safety facilities of a highway in Northwest China are evaluated by the analytic hierarchy process (AHP) one by one. Thus, the evaluation index system of highway safety facilities adaptability is established. Taking Qinghai Expressway in Northwest China as an example, this paper analyzes the characteristics, causes and differences of traffic accidents on highway sections in this province, so the applicability of different safety facilities is evaluated. And put forward the traffic safety facilities improvement and safeguard technology research. A new anti-collision device of flexible bridge with cushioning and energy dissipation has been developed, which can greatly improve the safety and comfort of the bridge. In order to provide the operational safety of Cha GE Expressway in Qinghai Province, the corresponding optimization measures are put forward. The conclusion provides the theoretical basis for the design, management, maintenance and reconstruction of traffic facilities for expressway traffic safety operation, which can prolong the service life of freeway and strengthen the safety of expressway operation in mountainous area. It is of great significance to reduce the occurrence of accidents.
