【摘要】：随着城市经济的发展、居民人口的增加以及汽车保有量的持续增长,交通问题日益严重。大力发展城市公共交通可为解决交通问题,特别是交通拥堵问题提供了一个有效的手段。目前,由于轨道交通的建设,在一定程度上补充了常规公交的不足。但是,轨道交通与公交系统自身存在的差异和局限,一方面需要对两者进行有机的调整,使两者表现出更高的协同性;另一方面要求公交系统对公交枢纽进行相应的调整,使得城市公共交通在以轨道交通为主干的情况下,充分发挥公交系统的优势。本文基于复杂网络理论对城市公共交通协同性及Hub节点进行了深入的研究。针对城市公共交通协同性的优化、公交系统枢纽Hub节点的定位、交通网络鲁棒性的增强以及如何提高城市公共交通整体服务水平和运输效率,主要进行了以下几个方面的研究:首先,对复杂网络理论及城市公共交通系统进行了系统化的介绍,并对城市公共交通网络的协同性关系、城市公共交通枢纽的分类进行了研究。同时从复杂网络的角度出发,对城市公共交通系统的协同性进行了重新的定义,并对城市公共交通枢纽的研究方法进行了分析和归纳。其次,利用L、P空间法和复杂网络理论,在对城市公交站点网络及换乘网络拓扑结构分析的基础上,对兰州市公交网络的静态特性和可靠性进行了研究。接着通过一定的复合加载机制,构造了常规公交与轨道交通组合而成的复合加载站点网络模型和复合加载换乘网络模型,同样从网络静态特性和可靠性两个方面,对复合加载网络进行了协同性研究,并通过一定的策略,对复合加载网络协同性进行了优化。实证以兰州市公交网络及兰州市公交网络和轨道交通组成的复合加载网络进行对比分析。研究表明,轨道交通与公交组成的复合加载网络表现出了较高的可达性、较大的客流承载量及较高的可靠性,而且通过一定的优化机制,复合加载网络可以表现出更高的协同性。最后,本文基于复杂网络理论,以灰色关联度法,整合复杂网络不同的特征参数,对网络的关键Hub节点进行了综合挖掘评估研究,并借助兰州市公交站点网络验证了方法的有效性。在此基础上,通过复杂网络理论与魅力度法的结合,将网络Hub节点的概念进一步引入到城市公共交通枢纽点选址问题的研究中,并以兰州市公交网络为基础,对公交网络枢纽点的选址进行了实证分析。通过对实证的研究,本文可为城市公共交通网络的合理规划布局及有序发展提供参考意见。
[Abstract]:With the development of urban economy, the increase of resident population and the continuous increase of vehicle ownership, traffic problems are becoming more and more serious. The development of urban public transport can provide an effective means to solve traffic problems, especially traffic congestion. At present, due to the construction of rail transit, to a certain extent complements the shortcomings of conventional public transport. However, the differences and limitations of rail transit and public transport system itself, on the one hand, need to adjust the two to make the two show a higher degree of synergy; on the other hand, the public transport system is required to adjust the public transport hub accordingly. It makes the urban public transportation give full play to the advantages of the public transport system under the condition of taking the rail transit as the main trunk. Based on the complex network theory, this paper makes a deep research on urban public transport synergy and Hub nodes. Aiming at the optimization of urban public transport coordination, the location of hub Hub node, the enhancement of traffic network robustness, and how to improve the overall service level and transportation efficiency of urban public transport. First of all, the theory of complex network and urban public transport system are systematically introduced, and the cooperative relationship of urban public transport network is introduced. The classification of urban public transport hubs is studied. At the same time, from the point of view of complex network, this paper redefines the synergy of urban public transport system, and analyzes and summarizes the research methods of urban public transport hub. Secondly, the static characteristics and reliability of the public transport network in Lanzhou are studied based on the analysis of the topological structure of the bus station network and the transfer network by using the LNP space method and the complex network theory. Then, through a certain compound loading mechanism, the network model of the composite loading station and the composite loading transfer network are constructed, which are composed of conventional public transport and rail transit. The static characteristics and reliability of the network are also discussed in terms of the static characteristics and reliability of the network. The synergism of composite loading network is studied and optimized by certain strategy. A comparative analysis is made between Lanzhou public transport network and the composite loading network composed of Lanzhou public transport network and rail transit. The research shows that the complex loading network composed of rail transit and public transportation has higher reachability, larger passenger flow carrying capacity and higher reliability, and through certain optimization mechanism, The composite loading network can show higher synergy. Finally, based on the theory of complex network and grey relational degree method, the key Hub nodes of the network are comprehensively excavated and evaluated by integrating the different characteristic parameters of the complex network. The effectiveness of the method is verified by the network of public transport stations in Lanzhou. On this basis, through the combination of complex network theory and charm degree method, the concept of network Hub node is further introduced into the study of urban public transport hub location problem, and based on Lanzhou public transport network. The location of the hub point of public transport network is analyzed empirically. Through the empirical research, this paper can provide reference for the rational layout and orderly development of urban public transport network.
