【摘要】:“公交優(yōu)先”是解決城市交通問題的有效方法。由于軌道交通系統(tǒng)具有大運量、速度快、準點率高等優(yōu)點,國內(nèi)已有數(shù)十個城市建成或正在建設城市軌道交通系統(tǒng)。但由于軌道交通系統(tǒng)的線路較為固定,輻射范圍有限,導致在其影響范圍之外的客流可能無法到達軌道交通站點;且由于城市建設初期的公交規(guī)劃中并沒有將軌道交通考慮在內(nèi),導致軌道交通和常規(guī)公交系統(tǒng)嚴重脫節(jié),兩者之間缺乏協(xié)作性。針對此類問題,本文提出了適應軌道交通站點的接運公交線路布設優(yōu)化方法,通過合理設置接運公交線路,擴大軌道交通的間接影響范圍,充分發(fā)揮其大運量的特點,同時使軌道-接運公交系統(tǒng)性能達到最優(yōu),促進整個城市公共交通系統(tǒng)良好運行。 本文結(jié)合國內(nèi)外研究現(xiàn)狀,對軌道交通與常規(guī)公交系統(tǒng)之間的協(xié)調(diào)運行,以及軌道交通與接運公交之間的線路優(yōu)化等問題進行了闡述,結(jié)合目前所取得的主要成果以及目前研究中所存在的問題,制定了本文的研究思路以及技術(shù)路線。對常規(guī)公交系統(tǒng)線路規(guī)劃的一般理論和方法進行了分析,并結(jié)合接運公交系統(tǒng)優(yōu)化問題,采取解優(yōu)法對軌道-接運公交線路優(yōu)化問題進行分析。 針對接運公交線網(wǎng)優(yōu)化問題,以軌道-接運公交系統(tǒng)總成本最小為最優(yōu)目標,,考慮到線路長度、線路重復系數(shù)及模型參考值等為約束條件,本文建立了軌道-接運公交線路優(yōu)化的數(shù)學模型。針對此數(shù)學模型,依靠一般的數(shù)學方法求解有一定的難度,所以本文對幾種典型的啟發(fā)式算法進行分析,最后選取遺傳算法作為模型的求解算法。此外,在分析比較幾種評價方法的基礎上,提出建議選用DEA作為接運線網(wǎng)效益的評價方法。 在對長春市公共交通系統(tǒng)分析的基礎上,以軌道交通4號線作為本文的目標線路,選取其中的4個站點作為本文的分析對象,對其周邊的常規(guī)公交站點的布設進行了分析。在本文建立的優(yōu)化模型的基礎上,用遺傳算法對其進行了求解,得到了其周邊接運公交的最優(yōu)線路,驗證了本文所提出的優(yōu)化模型的可用性。并用DEA方法進行評價。最后結(jié)合本文研究中所忽略的問題,提出了下一步研究計劃。本文的研究方法為適應軌道交通的常規(guī)公交線路的線路優(yōu)化問題提供了一定的參考。
[Abstract]:Bus priority is an effective method to solve urban traffic problems. Because the rail transit system has the advantages of large capacity, high speed and high punctuality, dozens of cities have been built or are building urban rail transit system in China. However, due to the fixed lines of rail transit system and the limited radiation range, the passenger flow outside its influence range may not reach the rail transit station. Due to the fact that rail transit is not taken into account in the initial stage of urban construction, the rail transit and conventional public transport system are seriously disjointed, and there is a lack of cooperation between the two systems. Aiming at this kind of problems, this paper puts forward the method of optimizing the layout of transit line for rail transit station. By setting up the bus line reasonably, the indirect influence range of rail transit is enlarged, and the characteristics of mass transit are brought into full play. At the same time, the performance of rail-transit system is optimized, and the whole urban public transportation system is promoted to run well. In this paper, the coordinated operation between rail transit and conventional public transport system, and the route optimization between rail transit and transit system are discussed in combination with the current research situation at home and abroad. Combined with the main achievements and the existing problems in the present research, the research ideas and technical route of this paper are worked out. This paper analyzes the general theory and method of route planning of conventional public transport system, and combines the optimization problem of transit system, and adopts the optimization method to analyze the optimization problem of rail transit line. In order to solve the problem of bus network optimization, the minimum total cost of rail transit system is considered as the optimal target, and the line length, line repetition coefficient and model reference value are considered as the constraints. In this paper, the mathematical model of the rail-bus route optimization is established. It is difficult to solve this mathematical model by general mathematical methods, so this paper analyzes several typical heuristic algorithms, and finally selects genetic algorithm as the algorithm to solve the model. In addition, based on the analysis and comparison of several evaluation methods, it is suggested that DEA should be selected as the evaluation method for the efficiency of transportation network. Based on the analysis of the public transportation system in Changchun City, the paper takes track 4 of the rail transit as the target line of this paper, and selects 4 stations as the analysis object, and analyzes the layout of the routine bus stations around it. On the basis of the optimization model established in this paper, the genetic algorithm is used to solve the problem, and the optimal route of the peripheral transit is obtained, which verifies the availability of the proposed optimization model. DEA method is used to evaluate. Finally, combined with the problems neglected in this study, the next research plan is put forward. The research method in this paper provides a certain reference for the route optimization of conventional bus routes.
