【摘要】：快速城市化推动着城市道路基础建设的发展,加之城市道路的改建养护维修,城市道路占路施工现象逐渐增多。为了避免施工路段交通事故,保证现场管理秩序,施工区交通组织研究至关重要。首先,明确施工区各功能区段的划分,结合交通流理论对占路施工区人、车、路、环境的交通特性进行了分析。以交通特性为基础,分析交通组织原则,对占路施工区交通组织进行理论研究。参照相关标准给定占路施工区各区段的长度计算公式;分析阐述各区段交通标志、标线的设置情况及其作用,并通过构建驾驶员行驶模型和交通标志认知模型,推导得到交通标志前置距离的计算公式;对占路施工区限速值的影响因素进行分析,构建了占路施工区Panel Data限速模型。其次,借助Vissim对占路施工区交通组织进行了仿真研究。以排队长度、平均延误等参数为指标对仿真实验进行评价,并与理论分析结果进行对比,给出了作业区长度、上游过渡区长度、交通标志前置距离以及限速值的最佳推荐值。在阐述占路施工交通影响范围概念的基础上,借助Vissim动态交通分配,以饱和度为评价指标,对施工前后路网进行分析,从而得到占路施工区交通影响范围。最后,对占路施工区交通组织进行评价,以饱和度、平均车速、交通密度和平均延误为评价指标,采用多指标综合评价方法构建评价体系,得到占路施工区交通组织综合评价函数界限值。
[Abstract]:Rapid urbanization promotes the development of urban road infrastructure, in addition to urban road maintenance and repair, urban road construction phenomenon gradually increased. In order to avoid road traffic accidents. To ensure the order of site management, the study of traffic organization in construction area is very important. First of all, make clear the division of each functional section of construction area, combined with the traffic flow theory to the people, cars, roads in the construction area. The traffic characteristics of the environment are analyzed. Based on the traffic characteristics, the principles of traffic organization are analyzed. The traffic organization of the construction area is studied theoretically. The formula for calculating the length of each section of the construction area is given according to the relevant standards. This paper analyzes and expounds the setting and function of traffic signs and signs in each section, and deduces the calculation formula of the leading distance of traffic signs by constructing the driving model and the cognitive model of traffic signs. Based on the analysis of the influencing factors of the speed limit of the Zhanlu construction area, the Panel Data speed limit model of the Zhanlu construction area is constructed. Secondly, the speed limit model of the Zhanlu construction area is constructed. With the aid of Vissim, the traffic organization in the construction area is simulated. The parameters such as queue length and average delay are taken as indicators to evaluate the simulation experiment, and the results are compared with the theoretical analysis results. The optimal recommended values of operation area length, upstream transition area length, traffic sign leading distance and speed limit are given. With the help of Vissim dynamic traffic distribution, taking saturation as the evaluation index, the road network before and after construction is analyzed, and the traffic impact range of the road construction area is obtained. Finally. Based on the evaluation of traffic organization in Zhanlu construction area, the evaluation system is constructed by using multi-index comprehensive evaluation method, taking saturation, average speed, traffic density and average delay as evaluation indexes. The limit value of comprehensive evaluation function of traffic organization in construction area of Zhanlu is obtained.
