【摘要】：伴随城市化水平和机动化需求的提高,城市道路拥堵现象日益严重。面对拥堵问题,我国普遍采用“建设城市快速路和干路”来解决,将“干路运输效率等同于整个路网的运输效率”,忽视了支路的重要作用,支路网缺失。支路缺失是国内城市路网的通病,不仅造成城市路网等级结构失调,路网整体运输效率下降；而且降低了步行、自行车、公交的竞争力,交通结构失调,居民出行不便。然而,我国在城市支路建设时往往不知道在哪衔接、如何衔接,干、支路衔接存在诸多问题。支路不仅不能服务于干路的溢出交通,反而增加了干-支交叉口节点的交通压力。基于上述情况,本文对国内外支路体系发达地区的理论和实践进行研究,在干路可穿越特性理论分析基础上,借助VISSIM进行仿真测试,形成干-支交叉口规划技术方法,弥补我国干-支交叉口衔接技术的不足。并结合干-支交叉口规划优秀案例的分析,总结干-支交叉口衔接模式。论文的第一章主要介绍研究的背景及意义,明确研究的技术路线与框架。第二章介绍了于-支交叉口的基本模式,主要包括图形模式、交通方式和交通组织形式,通过这三种形式的组合可形成交叉口的若干种衔接模式,为后续研究做铺垫。论文的主体部分是第三、四章。第三章基于支路相邻的干-干交叉口信号配时,提出了干-支交叉口可利用绿灯时长的计算方法,借助VISSIM软件对干-支交叉口进行交通仿真分析,结果表明通过合理设计、配时的干-支交叉口对干路的通行能力、车速的影响极小。第四章对国内外城市干-支路网及干-支交叉口衔接模式的典型案例进行归纳与分析,比较其差异性,总结干-支衔接模式及其适用性。并对车道边际效用以及干、支路,主、辅车道资源增减对交通及城市功能的影响分析,得到车道资源合理配置的一般性方法。论文的第五章为结语部分,对全文的研究过程及研究成果进行总结。
[Abstract]:With the city and the level of motorization demand increase, city road congestion is becoming increasingly serious. Facing the congestion problem, commonly used in our country "the construction of city road and road to solve," road transport efficiency is equivalent to the entire network transport efficiency, the importance of the branch, branch network branch deletion deletion. Is the common problem of domestic city road network, not only caused structural imbalance of city road network hierarchy, decreased overall road transportation efficiency; and reduce the pedestrian, bicycle, bus competition, traffic structure imbalance, residents travel inconvenience. However, in our country city branch construction often do not know where to cohesion, cohesion, stem, branch connection there are many problems. Not only can not serve the overflow traffic branch roads, but increased the dry branch intersection node traffic pressure.
Based on the above situation, this paper studies the theory and practice of domestic and foreign branch system in developed regions, on the main road through the characteristics on the basis of theoretical analysis, simulation test by VISSIM, the formation of dry branch intersection planning method, make up for China's dry branch intersection link technology shortcomings. Combined with excellent dry analysis case planning branch of the intersection, the intersection between a summary of dry mode.
The background and significance of the paper the first chapter mainly introduces the research, clarifies the research technical route and framework. The second chapter introduces the basic model to support the intersection, including graphics mode, traffic mode and traffic organization, formed some kinds of convergence model of intersection through the combination of these three forms of groundwork for the follow-up study.
The main part of the thesis is the third, fourth chapter. The third chapter branch adjacent dry dry intersection signal timing based on proposed, dry branch intersection method to calculate the length of the green, with the help of VISSIM software on the dry branch intersection traffic simulation analysis, the results show that the reasonable design, with the dry branch intersection on the trunk road traffic capacity, minimal impact speed. In the fourth chapter of the domestic and foreign city dry branch network and dry - a typical case of intersection branch connection model were summarized and analyzed, compare their differences, summarizes the dry branch connection model and its applicability. And the marginal utility of lane and stem, branch the main, auxiliary analysis, impact on traffic and city change lane resource function, general methods of rational allocation of resources in the lane.
The fifth chapter of the thesis is the concluding part, which summarizes the research process and research results of the full text.
