【摘要】 城市轨道交通作为缓解交通压力的一种非常有效的交通方式,以其速度快、运量大、时间准、污染少、安全性好等被越来越多的城市所采用。随着我国一些城市轨道交通线路的大规模兴建,轨道交通线路由单线变为多线,并逐渐形成路网。在轨道交通网络化运营的背景下,其运输能力问题的研究重点必将从车站与线路转向路网。城市轨道交通路网承载能力的计算与评价是一个全新的研究领域,探索性较强,将城市轨道交通路网作为一个系统来研究,由于其复杂性,其概念和计算方法还较少有人涉及。如何提供合理的计算方法,还需从其概念体系构架等方面进行系统的研究与深化。因此,本文关于城市轨道交通路网承载能力问题的研究具有一定的必要性。首先从路网中最基本的线路关系入手,讨论了五种典型的城市轨道交通路网结构类型；分析提出了城市轨道交通路网结构评估指标；给出了城市轨道交通路网的拓扑描述,构建了城市轨道交通路网的数学模型。其次对城市轨道交通运输能力的有关概念进行了简要的回顾和全面综述,提出了城市轨道交通路网承载能力的概念,在此基础上分析了城市轨道交通路网承载能力的特点及其概念意义；重点分析研究了城市轨道交通路网承载能力的影响因素；给出了城市轨道交通路网承载能力评估指标；简要介绍了备用能力的概念及其模型。最后分析了城市轨道交通与道路交通路径选择行为因素的异同,得出了城市轨道交通乘客路径选择的影响因素；考虑拥挤条件、舒适度及换乘排队时间,建立了更加精确合理的乘客出行路径阻抗函数；给出了区域备用能力的定义并将其作为路网承载能力的度量指标,由此建立了相应的双层规划模型,给出了模型的求解算法；并利用上述理论和计算方法对北京市轨道交通路网承载能力进行了实证研究。更多还原

【Abstract】 Urban rail transit is an effective mean of transportation to ease the traffic pressure. It is used in more and more large and medium-sized cities because of its large capacity, rapidity, punctuality, less pollution. Along with the large-scale construction of urban rail transit lines in china, urban rail transit lines changed from a single line into a network. In the context of urban rail transit network, the focus of urban rail transit carrying capacity will be converted from the line to network. The methods for calculating and evaluating the loading capacity of urban rail transit network are some new research domains, and of more challenges. Regarding urban rail transit network as a system, the researchers have done little things about the concepts and theories of network capacity because of its complexity. How to provide a reasonable method of calculating the loading capacity needs to do more research. This thesis on urban rail transit network loading capacity is necessary.First of all, the dissertation analyzes the basic relations between urban rail transit lines and studies five characteristic structures of urban rail transit, proposes the evaluation indicators of urban rail transit network structure. At last this thesis shows the topology description and constructs the mathematical model of the urban rail transit network.Secondly, the concept of urban rail transit network loading capacity is proposed after brief review and entirely summarization of urban rail transit carrying capacity, based on this analysis of urban rail transit network loading capacity characteristics and the concept of significance. This section focused analyzes the main features and the influencing factors of urban rail transit network loading capacity, proposes the evaluation indicators of urban rail transit network loading capacity. Finally, the concept and model of the reserve capacity are briefly introduced.Finally, the major factors influencing the path choice are proposed by comparing the differences of path choice behavior between traffic and urban rail transit. Considering crowded conditions, comfort and the queuing time whiling transferring to another rail, we get the more reasonable path cost function. The zonal reserve capacity is defined and adopted as an integrated performance index to urban rail transit network loading capacity. Mathematically, it is formulated as a bi-level model, and gives the algorithm of model. This thesis put forward the cumulating methods of urban rail transit network loading capacity and applies the models and methods above to Beijing urban rail transit network.更多还原
