【摘要】：随着我国城镇化进程的加快,汽车保有量不断增长,交通拥堵和污染问题日趋严重。对现有道路设施资源进行充分挖掘和优化,提高道路的通行能力,是缓解交通问题的有效手段。在城市道路网络中,交叉口是瓶颈部位,故交叉口运行状态的优化,有助于提高整个路网的通行效率。两相位交叉口在城市交叉口中占有很大的比重,对其进行优化研究具有非常现实的意义。本论文以两相位交叉口为研究对象,通过VISSIM仿真软件,分析两相位交叉口不同导向车道功能划分方式对于交叉口拥挤程度和通行效率的影响,进而得出常见两相位交叉口最佳的导向车道功能设置依据。首先,通过查阅国内外相关文献、规范、技术手册等资料,了解国内外的相关研究现状,从平面交叉口的交通组织优化、导向车道功能布置现有规范和依据、交通仿真技术的发展与应用三个方面对国内外的研究现状进行了总结。其次,制定详细的调查方案,对两相位交叉口的现状分布、类型及导向车道布置、信号配时与适应交通量等进行调查分析,在此基础上建立了四进口道导向车道布置和转向流量分布完全相同的两相位交叉口基本模型,四进口道导向车道布置和转向流量分布不同的混合模型。然后,利用VISSIM仿真软件对两相位交叉口进行仿真实验,验证现有导向车道设置依据的适用性,分析现有依据的不足。在此基础上,制订详细的仿真方案,以各进口道的转向流量比例为变量,以排队长度和延误时间为评价指标,依次进行基本模型和混合模型的仿真实验。最后,分析总结基本型交叉口仿真实验结果,得到了三车道两相位交叉口左转专用导向车道和右转专用导向车道的定量化设置依据,两车道两相位交叉口导向车道组合最优的定量化设置依据。通过混合型交叉口的仿真实验对比分析,证明按照基本型交叉口的结论进行两相位交叉口单个进口道的导向车道设置依据是可行的。在此基础上,汇总了两相位交叉口各种类型进口道导向车道设置依据,并给出了实际应用时的流程和说明。
[Abstract]:With the acceleration of urbanization in our country, the number of vehicles is increasing, and the problems of traffic congestion and pollution are becoming more and more serious. The existing road facilities resources are fully excavated and optimized to improve the capacity of roads. In the urban road network, intersection is the bottleneck position, so the operation state of intersection is optimized. Two-phase intersections occupy a large proportion in urban intersections, and it is of great practical significance to optimize them. In this paper, two-phase intersections are taken as research objects. By means of VISSIM simulation software, this paper analyzes the influence of different lane function partition methods on congestion degree and traffic efficiency of two-phase intersection, and then obtains the best guidance lane function setting basis of common two-phase intersection. Through consulting relevant documents, norms, technical manuals and other materials at home and abroad, to understand the current situation of research at home and abroad, from the intersection traffic organization optimization, guidance lane function layout of the existing norms and basis, The development and application of traffic simulation technology have summarized the research status at home and abroad. Secondly, the detailed investigation scheme has been established, and the distribution, type and lane layout of two-phase intersection have been made. Based on the investigation and analysis of signal timing and traffic volume adaptation, the basic model of two-phase intersection with the same distribution of steering lane and steering flow is established. Four mixed models of different lane layout and steering flow distribution in the entrance lane. Then, the simulation experiment of two-phase intersection is carried out by using VISSIM simulation software to verify the applicability of the existing guidance lane setting basis. Based on the analysis of the deficiency of the existing basis, a detailed simulation scheme is developed, with the ratio of the steering flow of each inlet as the variable, the queue length and the delay time as the evaluation index. Finally, the simulation results of the basic intersection and the mixed model are analyzed and summarized, and the quantitative setting basis of the left turn special leading lane and the right turn special leading lane of the three lane and two phase intersection are obtained. The quantitative setting basis for the optimal combination of two lanes and two phase intersections is obtained. The simulation results of hybrid intersections are compared and analyzed. It is proved that according to the conclusion of the basic type intersection, it is feasible to set the guiding lane of the single entrance lane at the two-phase intersection. On this basis, the author summarizes the guidance lane setting basis of the different types of entrance lane at the two-phase intersection. The flow chart and explanation of practical application are also given.
