【摘要】：城市公交作为城市基础设施的重要组成部分,是城市居民出行的最主要方式。发展城市公共交通不仅能有效缓解城市交通拥堵问题,还是改善城市人居环境,促进城市可持续发展的必然要求,是提高交通资源利用效率、缓解城市拥堵、降低交通污染、节约土地资源的重要手段。在当前国家大力发展公共交通的背景下,如何打造和谐高效的高品质公共交通体系,对于城市的发展有着重要意义。城市公交系统作为一个典型的、开放的、复杂的巨系统,其运行规律和内部结构及其复杂。近几年发展起来的复杂网络方法,为我们从宏观、整体的角度研究复杂系统提供了一个新的视角和新的方法。本文运用复杂网络基本理论和基本方法,对城市公交网络拓扑结构进行了分析,并结合南京公交网络实例,阐述了复杂网络理论对于分析城市公交网络结构的意义,同时也为日后对于南京市公交网络的研究奠定了理论和数据的支持。本文的主要工作主要有以下几个方面：首先,在介绍复杂网络的基本概念、基本理论、模型演化和主要特征参数的基础上,结合城市公交网络的特点,从定性和定量的角度系统分析了城市公交网络的复杂性表现形式,并给出了公交网络抽象建模的方法。其次,以南京市常规公交为例,构建了南京市公交站点网络模型和换乘网络模型,并利用Gephi网络分析软件,分别统计分析了站点网络和换乘网络的各指标值的分布情况,分析了两种模型网络的无标度特性和小世界等特性。最后,以网络效率为衡量指标,给出了复杂网络分析结果的一个应用方向,即对网络枢纽节点的布设进行规划。并结合南京市公交网络的分析结果,以实例说明了网络枢纽辨识度较高,为网络枢纽节点的规划布局以及建设进度的检验提供了新的思路。
[Abstract]:City bus as an important part of city infrastructure, is the main way of city residents. The development of city public transport not only can effectively alleviate the city traffic congestion, or improve the city living environment, an inevitable requirement to promote the sustainable development of the city, is to improve the utilization efficiency of traffic resources, alleviate the city traffic, reduce traffic pollution, an important means conservation of land resources. In the current state of the development of public transport in the background, how to build a harmonious and efficient high-quality public transport system, is of great significance for the development of the city. The city bus system as a typical, open, complex system, and its operation rules and internal structure and complex. The complex network method in recent years, we from the macro perspective, the research of complex system provides a new perspective and a new method for this. This paper uses the basic theory of complex networks and the basic method of city bus network topology are analyzed, combined with the Nanjing transit network examples, expounds the theory of complex network analysis for city bus network structure and meaning, but also for the day after the study for the Nanjing city transit network laid the theoretical and data support the main work of this paper. Mainly has the following several aspects: first, the basic concepts, introduces the basic theory of complex networks, the basic model of evolution and characteristics of the main parameters, combined with the characteristics of city bus network, from the perspective of qualitative and quantitative analysis of the complexity of system form the city bus network, and gives the method of public transit network abstract modeling secondly, taking Nanjing city bus as an example, the construction of Nanjing city bus station network model and transfer network model, and using Gephi network analysis software, Respectively, statistical analysis of the distribution of each index site network and transfer network value, analyzes the scale and small world characteristics of two kinds of model of network. Finally, the network efficiency index, gives an application direction of complex network analysis results, the layout of network hub node planning the results of analysis. Combined with the Nanjing city transit network, to illustrate the network hub identification degree, provides a new way to test network hub nodes layout and construction schedule.
