【摘要】：隨著我國城市化水平的不斷提高,各種社會經(jīng)濟活動也越發(fā)地活躍,城市交通出行需求增長旺盛,進而給城市帶來了越來越大的交通壓力。為了緩解城市內部交通壓力,提升城市運輸效率,我國很多大城市都已經(jīng)著手開展了快速路的建設工作,在規(guī)劃過程中怎樣確定其規(guī)劃里程、如何進行規(guī)劃布局,快速路設計階段如何選擇立交形式,建設什么樣的快速路,匝道以及出入口等配套設施怎么設置更為科學等等問題,都成為了快速路規(guī)劃與設計過程中的關鍵問題。 本論文總結了快速路在國內外的發(fā)展演變歷程,掌握了快速路的概念,分析了快速路的交通特性和建設條件,闡明快速路在城市道路網(wǎng)中的功能。 本論文運用“時空消耗理論”提出了城市快速路網(wǎng)合理長度的計算方法；結合前人研究成果,提出改進的基于“交通單元”劃分的快速路網(wǎng)的布局方法,并給具體的布局流程。 針對快速路的節(jié)點設計等關鍵問題,本論文總結了幾種常用的立交類型,分析了它們各自的優(yōu)缺點,指出了各種類型立交所適用的條件；按照快速路出入口的設計原則,計算了相鄰出入口之間的最小距離,給出了不同類型出入口的凈間距推薦值；從交通設計的角度,給出了幾種出入口與輔路相接處交通組織的改進方法。 最后本論文按照所研究內容對濟南市快速路網(wǎng)的規(guī)劃布局和節(jié)點設計等關鍵問題進行了實例研究。
[Abstract]:With the development of urbanization in China, all kinds of social and economic activities are becoming more and more active, and the demand for urban transportation is increasing, which brings more and more traffic pressure to the city. To improve the efficiency of urban transportation, many large cities in China have already started to build expressway. How to determine the planning mileage, how to plan layout, how to choose the interchange form in the expressway design stage in the planning process, What kind of expressway construction, how to set up the supporting facilities, such as ramp, entrance and exit and so on, have become the key problems in the process of expressway planning and design. This paper summarizes the development and evolution of expressway at home and abroad, grasps the concept of expressway, analyzes the traffic characteristics and construction conditions of expressway, and clarifies the function of expressway in urban road network. In this paper, a method of calculating the reasonable length of urban expressway network is put forward by using "space-time consumption theory", and an improved layout method of expressway network based on "traffic unit" is put forward in combination with the previous research results. And give the specific layout process. Aiming at the key problems such as node design of expressway, this paper summarizes several kinds of common interchange types, analyzes their respective advantages and disadvantages, points out the applicable conditions of various types of interchange, and according to the design principle of expressway entrance and exit, The minimum distance between the adjacent entrances and exits is calculated, the net distance between the different types of entrances and exits is given, and from the point of view of traffic design, the improvement methods of traffic organization at the junctions between the entrances and the auxiliary roads are given. Finally, according to the research content, the paper studies the key problems of Jinan Expressway network planning, layout and node design.
