【摘要】：當前,由于國內(nèi)各大城市交通擁堵十分嚴重,許多一、二線城市都在修建城市軌道交通以緩解城市擁堵。城市軌道交通建設初期難以短時間形成交通網(wǎng)絡,存在可達性差的缺點。同時,城市軌道交通線路的固定性,不可隨意更改,導致其靈活性不強,直達率不高,吸引客流受到局限。因此,利用地面常規(guī)公交線路設置靈活,營運成本相對較低,覆蓋面廣,可達性好等特點,使其與城市軌道交通接駁可以較好的促進公共交通發(fā)展,達到緩解城市交通擁堵的作用。本文首先對地面常規(guī)公交與城市軌道交通的內(nèi)涵及特點進行了界定;對比了兩者之間的技術特性、服務范圍、綜合效益等特性;研究了兩者之間的協(xié)調、競爭機理,線路空間關系,以及功能關系。接著,從接駁站點銜接、線網(wǎng)空間關系方面分析了兩種交通形式間的協(xié)調機理;分析了接駁系統(tǒng)間乘客交通出行成本組成、出行時間組成,并分別建立了數(shù)學模型。而后,從乘客出行需求和公共交通系統(tǒng)兩個方面就地面常規(guī)公交線網(wǎng)在優(yōu)化調整過程中的影響因素進行了研究,并從宏觀定性和局部定量的角度研究了接駁過程中地面常規(guī)公交線網(wǎng)優(yōu)化調整的原則和方法。最后,建立了基于乘客交通出行時間最短,交通出行費用最小以及營運者營運成本最小的數(shù)學優(yōu)化模型;并對求解模型的常見算法進行了分析對比,選用遺傳算法利用MATLAB工具箱對優(yōu)化問題進行求解;并通過實例進行了分析說明。通過接駁優(yōu)化能夠合理地降低軌道交通沿線地面常規(guī)公交線路的重復系數(shù),提高沿線公共交通的通行效率,緩解沿線交通擁堵;同時,提高軌道交通沿線影響范圍內(nèi)乘客出行效率,擴大城市軌道交通的影響范圍,改變軌道交通影響范圍內(nèi)乘客出行交通結構,增大軌道交通的分擔比例,從根本上起到緩解城市擁堵的作用。
[Abstract]:At present, due to the serious traffic congestion in major cities in China, many first and second tier cities are building urban rail transit to ease urban congestion. It is difficult to form a traffic network in the early stage of urban rail transit construction. At the same time, the fixed nature of urban rail transit lines, can not be changed at will, resulting in its flexibility is not strong, direct rate is not high, attract passenger flow is limited. Using the characteristics of flexible ground routine bus lines, relatively low operating cost, wide coverage, good accessibility and so on, it can better promote the development of public transport. To alleviate the role of urban traffic congestion. Firstly, this paper defines the connotation and characteristics of ground routine public transport and urban rail transit. The technical characteristics, service scope, comprehensive benefit and so on are compared. The coordination mechanism, competition mechanism, line space relationship and function relationship between the two systems are studied. Then, the coordination mechanism between the two traffic forms is analyzed from the connection of the connection stations and the spatial relationship between the two traffic forms. The composition of passenger travel cost and travel time are analyzed, and the mathematical models are established respectively. From the passenger travel demand and the public transportation system, the paper studies the influencing factors of the ground routine bus network in the process of optimization and adjustment. From the macroscopic qualitative and local quantitative point of view, the paper studies the principles and methods of optimizing and adjusting the ground routine bus network in the connection process. Finally, the shortest travel time based on passenger traffic is established. The mathematical optimization model of the minimum travel cost and the minimum operating cost of the operator; The common algorithms for solving the model are analyzed and compared. Genetic algorithm is used to solve the optimization problem using MATLAB toolbox. Through the analysis of examples, it can reasonably reduce the repetition coefficient of the ground routine bus lines along the rail transit line, improve the efficiency of the public transport along the rail transit line, and alleviate the traffic congestion along the rail transit line. At the same time, improve the passenger travel efficiency along the impact area of rail transit, expand the impact range of urban rail transit, change the passenger travel structure within the impact area of rail transit, increase the share of rail transit. Fundamentally play a role in alleviating urban congestion.
