【摘要】：高速公路自1988年在我國(guó)興建以來(lái),對(duì)我國(guó)社會(huì)經(jīng)濟(jì)的快速發(fā)展做出了重要貢獻(xiàn),到2013年,我國(guó)高速公路里程已經(jīng)達(dá)到10.44萬(wàn)公里,高速公路網(wǎng)絡(luò)已經(jīng)覆蓋了我國(guó)大部分省市地區(qū),成為我國(guó)交通運(yùn)輸業(yè)及社會(huì)經(jīng)濟(jì)發(fā)展的重要紐帶,高速公路路網(wǎng)結(jié)構(gòu)逐步形成。高速公路以其特有的技術(shù)經(jīng)濟(jì)優(yōu)勢(shì),贏得了廣大交通出行者的青睞,同時(shí)汽車行業(yè)的迅猛的發(fā)展,使得我國(guó)高速公路交通需求快速增長(zhǎng),高速公路網(wǎng)部分路段通行能力已經(jīng)不能滿足現(xiàn)有需求,尤其是節(jié)假日期間特別明顯,從而影響整個(gè)高速公路網(wǎng)的運(yùn)行效率,為了保證高速公路便捷、高效、安全的運(yùn)行,本文從高速公路網(wǎng)整體出發(fā),研究高速公路路網(wǎng)容量及提升方法。論文的主要研究?jī)?nèi)容如下:首先,基于現(xiàn)有的路網(wǎng)容量研究理論,對(duì)路網(wǎng)容量的分類進(jìn)行了系統(tǒng)的梳理,按不同的原則劃分為不同的類型,并根據(jù)本文研究目標(biāo)提出高速公路路網(wǎng)容量的概念,同時(shí)界定了本論文研究的主要內(nèi)容。然后根據(jù)高速公路的特性,對(duì)影響高速公路路網(wǎng)容量的關(guān)鍵因素進(jìn)行了全面的分析。其次,基于先前學(xué)者路網(wǎng)容量研究模型方法,根據(jù)高速公路網(wǎng)的特點(diǎn),改進(jìn)了相關(guān)路網(wǎng)容量模型測(cè)算方法,構(gòu)建適合高速公路路網(wǎng)容量測(cè)算模型方法,并確定了影響高速公路路網(wǎng)容量測(cè)算的修正系數(shù)。再次,以陜西省高速公路網(wǎng)基礎(chǔ)設(shè)施及交通流數(shù)據(jù),利用時(shí)空消耗法測(cè)算分析了陜西省高速公路路網(wǎng)容量,并將其與節(jié)假日免費(fèi)通行期的交通流量作對(duì)比,分析目前高速公路網(wǎng)規(guī)模條件下陜西省高速公路交通供給與需求狀況。最后,從交通管控的角度出發(fā)提出了四種提高高速公路路網(wǎng)容量的關(guān)鍵方法,主要有高速公路關(guān)鍵節(jié)點(diǎn)路網(wǎng)容量提升方法、高速公路交通控制及誘導(dǎo)系統(tǒng)方法、高速公路主線可變限速控制方法以及高速公路入口匝道控制方法,并對(duì)每種方法的應(yīng)用原理及方法進(jìn)行了詳細(xì)的分析,以期能夠保證高速公路網(wǎng)內(nèi)交通流比較穩(wěn)定,減少或改善交通擁堵現(xiàn)象,最大化高速公路利用效率,從而實(shí)現(xiàn)提高高速公路路網(wǎng)容量的目的。
[Abstract]:Since the expressway was built in our country in 1988, it has made important contribution to the rapid development of social economy in our country. By 2013, the mileage of expressway in our country has reached 104,400 kilometers, and the expressway network has covered most provinces and cities of our country. It has become an important link for the development of transportation and social economy in our country, and the highway network structure has gradually formed. With its unique technical and economic advantages, the expressway has won the favor of the vast number of traffic travelers. At the same time, with the rapid development of the automobile industry, the traffic demand of expressway in China is growing rapidly. The capacity of some sections of the highway network can no longer meet the existing demand, especially during the holidays. In order to ensure the convenient, efficient and safe operation of the expressway, this paper starts from the whole expressway network. The main contents of this paper are as follows: firstly, based on the existing theory of highway network capacity research, the classification of highway network capacity is systematically sorted out and divided into different types according to different principles. According to the research objectives of this paper, the concept of highway network capacity is put forward, and the main content of this paper is defined. Then according to the characteristics of expressway, The key factors affecting the capacity of highway network are comprehensively analyzed. Secondly, based on the previous research model of highway network capacity, according to the characteristics of highway network, the related network capacity model calculation method is improved. The method of calculating the capacity of highway network is constructed, and the correction coefficient which affects the capacity of highway network is determined. Thirdly, based on the data of infrastructure and traffic flow of highway network in Shaanxi Province, The highway network capacity of Shaanxi Province is calculated and analyzed by using space-time consumption method, and compared with the traffic flow during the free traffic period during holidays. This paper analyzes the traffic supply and demand of expressway in Shaanxi Province under the condition of highway network scale. Finally, four key methods to improve the capacity of highway network are put forward from the point of view of traffic control. There are several methods to improve the network capacity of the key nodes of the expressway, the method of expressway traffic control and guidance system, the main line variable speed limit control method of expressway and the method of freeway on-ramp control. The application principle and method of each method are analyzed in detail in order to ensure the steady traffic flow in the expressway network, reduce or improve the traffic congestion, and maximize the efficiency of expressway utilization. In order to achieve the purpose of improving highway network capacity.
