【摘要】:隨著我國經(jīng)濟的快速發(fā)展,綜合交通運輸系統(tǒng)已經(jīng)走過了基礎(chǔ)設(shè)施建設(shè)快速發(fā)展和不斷完善的過程,綜合交通運輸體系中各種運輸方式已初具規(guī)模,,形成了各種運輸方式協(xié)同發(fā)展的態(tài)勢。然而,從綜合運輸網(wǎng)絡設(shè)施完善性,技術(shù)和設(shè)備先進性,生產(chǎn)效率高效性,各種運輸方式發(fā)展協(xié)調(diào)協(xié)調(diào)性等方面來看,我國距現(xiàn)代化綜合運輸體系建成尚有差距。故目前我國正處于綜合運輸結(jié)構(gòu)優(yōu)化和轉(zhuǎn)型的關(guān)鍵時期,其是構(gòu)建可持續(xù)發(fā)展社會的關(guān)鍵。國內(nèi)外經(jīng)驗表明,綜合運輸結(jié)構(gòu)優(yōu)化具有相當?shù)膹碗s性和不確定性,而現(xiàn)有理論并不完備。因此,本文對通道的綜合運輸結(jié)構(gòu)的調(diào)整及優(yōu)化進行研究,力求找出一種綜合運輸結(jié)構(gòu)優(yōu)化的新方法。 本文從全面性和可操作性出發(fā),應用綜合運輸規(guī)劃和非集計理論,對綜合運輸通道結(jié)構(gòu)優(yōu)化理論與方法進行了深入研究,主要有以下幾個部分: 首先,本文分析綜合運輸通道結(jié)構(gòu)優(yōu)化理論。通過對綜合運輸?shù)母拍畹难葑兗斑\輸結(jié)構(gòu)的分析,明確綜合運輸結(jié)構(gòu)優(yōu)化的概念,深入分析了綜合運輸?shù)募夹g(shù)經(jīng)濟特點和發(fā)展趨勢,并基于國家政策的影響分析,經(jīng)濟社會的發(fā)展水平,自然條件和科技水平,對綜合運輸結(jié)構(gòu)的調(diào)整和優(yōu)化進行分析,為綜合運輸通道結(jié)構(gòu)預測和優(yōu)化研究的提供理論基礎(chǔ)。 然后,本文研究了綜合運輸通道結(jié)構(gòu)預測方法。其包括通道吸引范圍的界定,以及交通路線選擇行為的分析,結(jié)合非集計理論并運用統(tǒng)計數(shù)據(jù),確定綜合運輸通道的路徑預測模型,為綜合運輸通道結(jié)構(gòu)優(yōu)化的提供數(shù)據(jù)支撐。 此外,本文研究了綜合運輸通道結(jié)構(gòu)優(yōu)化的方法。通過分析通道綜合運輸特性,確定了優(yōu)化思路,為通道綜合運輸結(jié)構(gòu)優(yōu)化方法的建立提供指導,在此基礎(chǔ)上構(gòu)建綜合運輸通道結(jié)構(gòu)優(yōu)化模型,實現(xiàn)對運輸通道合理運輸結(jié)構(gòu)的定量計算。 最后,本文以滬杭通道為例,對本文結(jié)構(gòu)優(yōu)化方法進行實例分析,驗證了本文方法的科學性與適用性。
[Abstract]:With the rapid development of China's economy, the integrated transportation system has gone through the process of rapid development and continuous improvement of infrastructure construction, and various transportation modes in the integrated transportation system have begun to take shape. Has formed each kind of transportation way coordinated development situation. However, from the aspects of comprehensive transportation network facilities perfection, advanced technology and equipment, high efficiency of production and coordination of development of various transportation modes, there is still a gap between China and the construction of modern integrated transportation system. Therefore, our country is in the key period of comprehensive transportation structure optimization and transformation, which is the key to the construction of sustainable development society. Experience at home and abroad shows that the optimization of integrated transport structure has considerable complexity and uncertainty, but the existing theory is not complete. Therefore, this paper studies the adjustment and optimization of the integrated transportation structure of the passage, and tries to find out a new method for the optimization of the integrated transportation structure. In this paper, from the viewpoint of comprehensiveness and maneuverability, applying the theory of integrated transport planning and disaggregation, the theory and method of structural optimization of integrated transportation corridor are studied. The main parts are as follows: first, This paper analyzes the theory of structural optimization of integrated transportation channels. Through the analysis of the evolution of the concept of integrated transport and the analysis of transport structure, the concept of optimization of integrated transport structure is clarified, and the technical and economic characteristics and development trend of integrated transport are analyzed in depth, and based on the analysis of the influence of national policies, The level of economic and social development, natural conditions and the level of science and technology, this paper analyzes the adjustment and optimization of the integrated transport structure, which provides a theoretical basis for the prediction and optimization of the structure of the integrated transportation channel. Then, this paper studies the integrated transportation channel structure prediction method. It includes the definition of channel attraction range and the analysis of traffic route selection behavior. Combining with disaggregate theory and statistical data, the path prediction model of integrated transportation channel is determined, which provides data support for the optimization of integrated transportation channel structure. In addition, this paper studies the optimization method of integrated transportation channel structure. Based on the analysis of the characteristics of the integrated transportation channel, the optimization idea is determined, which provides the guidance for the establishment of the optimization method of the integrated transportation structure of the channel. On the basis of this, the optimization model of the integrated transportation corridor structure is constructed. The quantitative calculation of the reasonable transportation structure of the transportation channel is realized. Finally, taking the Shanghai-Hangzhou passageway as an example, an example analysis of the structural optimization method in this paper is carried out, which verifies the scientific nature and applicability of this method.
