【摘要】：近年来,随着我国机动车保有量的不断升高,高速公路网所承担的交通量不断增加,越来越多的高速公路迫切需要进行改扩建。目前大多数高速公路进行改扩建施工过程中不封闭交通,车辆通行和改扩建施工同时进行,夜间由于高速公路交通量较小,施工对交通的干扰相对较小,许多工程选择在夜间进行施工,但目前我国对高速公路改扩建工程夜间临时交通安全设施的设置缺乏明确、合理的技术指导文件,给施工作业区的人员安全和车辆通行带来隐患。因而,对高速公路改扩建施工作业区夜间临时交通安全设施的设置进行研究,对提高夜间施工作业区的交通安全和通行秩序具有重要的意义和实际应用价值。作为《高速公路改扩建交通组织设计细则》的一个专题,本文从驾驶人夜间视觉特性、注意力、反应特性、操作特性和心理特性入手,分析了夜间条件下驾驶人心、生理水平对施工作业区驾驶的影响;根据高速公路改扩建施工作业区夜间道路路段的环境特性和交通特性,分析了夜间高速公路改扩建施工作业区影响交通安全的因素,系统阐述了高速公路改扩建施工作业区夜间临时交通安全设施的类型、形式及相关技术要求;根据高速公路改扩建工程移动施工作业区和固定施工作业区的不同特点,分别对两种施工作业区不同工况下夜间临时交通安全设施的设置进行了研究,并对相应的临时交通安全设施设置提出了具体要求。上述研究成果为《高速公路改扩建交通组织设计细则》相关条文的编制提供了技术支持和理论依据。
[Abstract]:In recent years, with the increasing number of motor vehicles in our country, the traffic volume on the highway network is increasing, and more and more expressways are urgently needed to be rebuilt and expanded. At present, most of the freeways are not closed in the construction process, and the traffic and expansion construction are carried out at the same time. At night, the highway is due to high speed public. The traffic volume of road is small, the interference of construction to traffic is relatively small, many projects are chosen at night to carry out construction. But at present, the setting of the temporary traffic safety facilities in the expressway reconstruction and extension project is lack of clear and reasonable technical guidance documents, which bring hidden danger to the safety of man and vehicle in the construction work area. The study on the setting of the night temporary traffic safety facilities in the construction area of the highway reconstruction and expansion is of great significance and practical application value for improving the traffic safety and traffic order in the night construction operation area. As a special subject of the traffic organization design rules for the expressway reconstruction and expansion, this article will pay attention to the night visual characteristics of the driver. Starting with the force, reaction characteristics, operation characteristics and psychological characteristics, the influence of driving in the construction operation area under the night condition is analyzed. According to the environmental characteristics and traffic characteristics of the night road section of the construction operation area, the influence of the traffic safety on the construction area of the high speed highway at night is analyzed. Factors, the types, forms and related technical requirements of the night temporary traffic safety facilities in the expressway reconstruction and extension construction area are systematically expounded. According to the different characteristics of the mobile construction operation area and the fixed construction operation area of the expressway reconstruction and expansion project, the safety facilities for the temporary traffic at night under the different working conditions of the two kinds of construction work areas are respectively carried out. The research results have provided the technical support and theoretical basis for the compilation of the detailed rules for the design of traffic organization for the expressway extension and expansion.
