【摘要】：伴隨城市化水平和機動化需求的提高,城市道路擁堵現(xiàn)象日益嚴(yán)重。面對擁堵問題,我國普遍采用“建設(shè)城市快速路和干路”來解決,將“干路運輸效率等同于整個路網(wǎng)的運輸效率”,忽視了支路的重要作用,支路網(wǎng)缺失。支路缺失是國內(nèi)城市路網(wǎng)的通病,不僅造成城市路網(wǎng)等級結(jié)構(gòu)失調(diào),路網(wǎng)整體運輸效率下降；而且降低了步行、自行車、公交的競爭力,交通結(jié)構(gòu)失調(diào),居民出行不便。然而,我國在城市支路建設(shè)時往往不知道在哪銜接、如何銜接,干、支路銜接存在諸多問題。支路不僅不能服務(wù)于干路的溢出交通,反而增加了干-支交叉口節(jié)點的交通壓力。 基于上述情況,本文對國內(nèi)外支路體系發(fā)達地區(qū)的理論和實踐進行研究,在干路可穿越特性理論分析基礎(chǔ)上,借助VISSIM進行仿真測試,形成干-支交叉口規(guī)劃技術(shù)方法,彌補我國干-支交叉口銜接技術(shù)的不足。并結(jié)合干-支交叉口規(guī)劃優(yōu)秀案例的分析,總結(jié)干-支交叉口銜接模式。 論文的第一章主要介紹研究的背景及意義,明確研究的技術(shù)路線與框架。第二章介紹了于-支交叉口的基本模式,主要包括圖形模式、交通方式和交通組織形式,通過這三種形式的組合可形成交叉口的若干種銜接模式,為后續(xù)研究做鋪墊。 論文的主體部分是第三、四章。第三章基于支路相鄰的干-干交叉口信號配時,提出了干-支交叉口可利用綠燈時長的計算方法,借助VISSIM軟件對干-支交叉口進行交通仿真分析,結(jié)果表明通過合理設(shè)計、配時的干-支交叉口對干路的通行能力、車速的影響極小。第四章對國內(nèi)外城市干-支路網(wǎng)及干-支交叉口銜接模式的典型案例進行歸納與分析,比較其差異性,總結(jié)干-支銜接模式及其適用性。并對車道邊際效用以及干、支路,主、輔車道資源增減對交通及城市功能的影響分析,得到車道資源合理配置的一般性方法。 論文的第五章為結(jié)語部分,對全文的研究過程及研究成果進行總結(jié)。
[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.
