【摘要】：我国正处于能源结构转型阶段,低碳交通是当前交通运输业实现能源结构转型的必然选择。常规公交作为传统意义上的低碳交通、绿色出行方式的一种,以其低出行成本、较大运量、较低碳排放等特点被广泛推广。然而常规公交的低碳性是建立在人均碳排放的基础上,并非天然的低碳交通方式,若公交线路客流量规模不足,则无法保证常规公交的低碳性,也就无法实现当前交通运输业的能源结构转型。因此本文对常规公交的低碳优化进行研究。本文对低碳理念、低碳交通以及低碳公交进行了研究,总结了公交线网的常用优化方法,并将其与低碳相融合,探究了公交车辆的碳排放及其相关；研究分析了影响公交线网的因素,并以此为基础,采用以出行者、公交运营方、环境三方综合考虑的双层优化模型,借助改进蚁群算法对模型进行求解常规公交线网的合理布设。基于低碳理念、低碳交通及其相关的内涵、特性,常规公交线网优化原则,公交车辆碳排放量系数等理论基础,结合当前我国公交线网的主要状况,对常规公交线网影响低碳优化的因素进行分析,并对一般公交线网的约束进行适当调整。在此基础上,建立了上层以总线网消耗最少,下层为乘客出行分配的双层优化模型。借助改进蚁群算法,将蚁群算法的劣势降低,以实现对常规公交线网低碳优化的目标。最后借助枣庄市中区为算例,优化该区域的公交线网,证明该优化方法合理有效。
[Abstract]:Our country is in the energy structure transformation stage, the low carbon transportation is the inevitable choice of the current transportation industry to realize the energy structure transformation. As a kind of traditional low carbon transportation and green travel mode, the conventional public transport is a kind of low travel cost. However, the low-carbon nature of conventional public transport is based on the per capita carbon emissions, not the natural low-carbon transport mode, if the bus line passenger flow scale is insufficient, It can not guarantee the low-carbon nature of conventional public transport, and it is impossible to realize the energy structure transformation of the transportation industry. Therefore, this paper studies the low-carbon optimization of conventional public transport. The low carbon transportation and low carbon public transport are studied, the common optimization methods of the bus network are summarized, and the carbon emission of the public transport vehicle and its correlation are explored, and the factors that affect the bus network are studied and analyzed. On the basis of this, a two-layer optimization model, which takes travelers, bus operators and environment into consideration, is adopted to solve the problem of reasonable layout of conventional bus network by means of improved ant colony algorithm, based on the concept of low carbon. Low-carbon transportation and its related connotation, characteristics, optimization principles of conventional bus network, carbon emission coefficient of public transport vehicles and other theoretical basis, combined with the current main status of public transport network in China, The factors affecting low carbon optimization of conventional bus network are analyzed, and the constraints of general bus network are adjusted appropriately. On this basis, the upper layer of bus network is established to consume the least. With the help of improved ant colony algorithm, the disadvantage of ant colony algorithm is reduced to achieve the goal of low carbon optimization of conventional bus network. Finally, with the aid of Zaozhuang city central district as an example, The optimization method is proved to be reasonable and effective.
