【摘要】：新型城镇化进程快速推进,社会经济持续快速增长,机动车保有量逐年增加。为缓解日益严重的城市交通拥堵和居民出行环境恶化的问题,相关部门采取多种改善措施,涵盖轨道交通建设、快速路网体系构建、道路改扩建、交通节点优化设计等,城市中各项交通基础设施建设项目愈来愈多。与单个施工作业区相比,同时期和相近范围内多个施工作业区的存在,对城镇道路交通运行将产生更多重要影响。故依托国家自然科学基金项目“城市道路多施工作业区交通影响分析与时序运作决策研究”(项目批准号:51408552),论文以城镇道路直通式多施工作业区为研究对象,以期为施工作业区交通组织和运行管理提供理论基础和决策支持。首先,明确城镇道路多施工作业区的内涵。多个施工作业区同期同步存在时,基于空间上的相对位置,将其分为直通式、交叉式和平行式多施工作业区。通过实地调研和归纳,总结城镇道路多施工作业区现状交通组织存在的问题。面向直通式多施工作业区,从宏观交通流运行、微观交通流运行方面,阐述直通式多施工作业区的特征。建立直通式多施工作业区非拥堵状态下速度-流量模型,明确大车率、施工作业区长度及距离交叉口的距离等因素对其影响。其次,采用关联指数表征有交叉口型直通式多施工作业区之间的关联程度,并以此界定相关施工作业区是否表现为多施工作业区的特性,进而结合郑州市长椿路上由于轨道交通站点施工形成的直通式多施工作业区进行实例应用;建立无交叉口型直通式多施工作业区VISSIM仿真模型,计算其通行能力,并构建多元非线性回归模型,判识无交叉口型直通式多施工作业区通行能力的主要影响因素,计算结果表明:期望速度、施工作业区间距、施工作业区长度对其的影响程度分别依次降低。最后,结合车流波动理论、车道数平衡理论及VISSIM仿真模拟,对城镇道路多施工作业区的车道数变化、施工作业区长度及间距、施工标志设置、限速、机非分离、围挡形式等提出相关策略建议。
[Abstract]:The new urbanization process is advancing rapidly, the social economy continues to grow rapidly, and the number of motor vehicles is increasing year by year. In order to alleviate the increasingly serious problems of urban traffic congestion and the deterioration of residents' travel environment, the relevant departments have adopted a variety of improvement measures, including the construction of rail transit, the construction of expressway network system, the reconstruction and extension of roads, the optimal design of traffic nodes, etc. There are more and more traffic infrastructure projects in the city. Compared with a single construction operation area, the existence of multiple construction operation areas in the same period and in similar scope will have more important influence on urban road traffic operation. Therefore, relying on the project of National Natural Science Foundation of China, "Traffic impact Analysis and time Series Operation decision Research of Urban Road Multi-construction area" (Project approval No.: 51408552N), the paper takes the urban road direct-through multi-construction operation area as the research object. In order to provide theoretical basis and decision support for traffic organization and operation management in construction operation area. First of all, make clear the connotation of urban road construction operation area. When multiple construction operation zones exist simultaneously, they are divided into three types: straight, cross and parallel construction operation areas based on the relative position in space. Through field investigation and induction, this paper summarizes the existing problems of traffic organization in urban road construction area. In this paper, the characteristics of direct-through multi-construction operation area are described from the aspects of macroscopic traffic flow operation and microscopic traffic flow operation. In this paper, a speed flow model is established under the condition of non-congestion in the straight through multi-construction operation area, and the influence factors such as the rate of the heavy car, the length of the construction area and the distance from the intersection are determined. Secondly, the correlation index is used to characterize the degree of correlation between the multi-construction operation areas with intersection type, and to define whether the related construction operation areas are the characteristics of multi-construction operation areas. Furthermore, combining with the practical application of the straight-through multi-construction operation area formed by the railway station construction on the Changzhou-Chun Road of Zhengzhou, the VISSIM simulation model of the straight-through multi-construction operation area without intersection is established, and its capacity is calculated. The multivariate nonlinear regression model is constructed to identify the main influencing factors of the capacity of the no-intersection-type straight-through construction area. The results show that the expected speed, the distance between the construction operation areas, and so on are the main factors that affect the capacity of the multi-construction operation area. The influence degree of the length of construction work area on it is decreased in turn. Finally, combined with the theory of vehicle flow fluctuation, the theory of lane number balance and VISSIM simulation, the change of lane number, the length and spacing of construction work area, the setting of construction sign, the speed limit and the non-separation of machine are analyzed. Put forward the relevant strategies and suggestions.
