【摘要】：城市交通网络系统是个复杂的巨系统。由于城市客货交通发生与分布的复杂性，城市交通网络研究需要关注城市交通生活的各个方面内容，如城市处于什么发展时期、将产生多少出行需求量、这些交通需求如何构成、城市路网该如何规划设计以满足现在及未来的交通需求等。在城市交通网络运行系统复杂性机理研究方面，近些年在复杂网络理论兴起的基础上已有了不少不同层次和方面的进展。如基于复杂网络拓扑角度进行统计分析，研究不同的网络拓扑结构下拥堵、堵塞等的传播机理；模拟建立具有真实复杂交通网络结构，，并研究其网络结构及运行状态演化规律等。纵观复杂网络理论及其相关应用研究，如流行病传播模型、舆论传播模型、因特网上信息包传递模型、能量网络传递模型等，均是从描述实际网络规律及特性出发，进而建立可以描述符合实际规律的复杂网络功能及状态演化模型。本文根据搜集的相关城市路网数据库，在现有国内外研究基础上，提出城市交通系统复杂性分析应分为“五个层次”，并在文中选择基于路网对偶法拓扑展开相应路网复杂性实证研究。本文第二章以北京、广州、西安为例，对比验证了城市规模下路网结构仍具有典型复杂网络特征，并尝试基于相关指标、如网络度指数、聚集系数、各类效率指数、网络介数等分析城市路网形成规律与交通现象，为进一步分析城市路网复杂性奠定了理论基础和分析框架；本文第三章通过分析ICN对偶法抽象误差，提出了结合路网属性进行连续性改进判断的RP-ICN对偶法，并以西安路网数据库为例进行了验证分析；本文第四章结合城市路网系统状态的研究需要，基于复杂网络“级联失效”理论研究思想，提出了结合城市宏观交通模型进行路网拥堵形成及演化复杂性研究的思路和方法，并依托“西安市城市综合交通模型数据库”进行了相关实证研究。本文最后对下一步如何结合城市路网复杂性研究成果进行复杂网络视角下的城市路网评价及设计优化进行了展望。
[Abstract]:Urban traffic network system is a complex giant system. Due to the complexity of the occurrence and distribution of urban passenger and freight traffic, the study of urban transportation network needs to pay attention to the various aspects of urban traffic life, such as what period of development the city is in, and how much travel demand will be generated. How to make up these traffic demands, how to plan and design the urban network to meet the present and future traffic demand, etc. In recent years, on the basis of the rise of complex network theory, there have been many progress in different levels and aspects in the study of complexity mechanism of urban traffic network operation system. For example, based on the statistical analysis of complex network topology, the propagation mechanism of congestion and congestion under different network topologies is studied. The network structure and the evolution law of running state are also studied. The complex network theory and its related application research, such as epidemic transmission model, public opinion transmission model, information packet transmission model on the Internet, energy network transmission model, etc., are all based on describing the laws and characteristics of the actual network. Furthermore, the function and state evolution model of complex network can be described according to the actual law. Based on the relevant urban road network database collected, this paper puts forward that the complexity analysis of urban transportation system should be divided into "five levels" on the basis of existing domestic and foreign research. In this paper, based on the dual topology of road network, the empirical study of road network complexity is carried out. In the second chapter, taking Beijing, Guangzhou and Xi'an as examples, it is verified that the road network structure still has typical complex network characteristics under the city scale, and tries to base on the related indexes, such as network degree index, aggregation coefficient, efficiency index, etc. The analysis of urban road network formation law and traffic phenomenon by network mesograph lays a theoretical foundation and an analytical framework for further analysis of urban road network complexity. Chapter three analyzes the abstract error of ICN duality method. The RP-ICN dual method combining the attribute of road network is put forward, and the verification and analysis of Xi'an road network database is carried out. Based on the theory of "cascade failure" of complex networks, this paper puts forward a method to study the complexity of road network congestion formation and evolution, which is based on the urban macro-traffic model. And rely on Xi'an city comprehensive traffic model database to carry on the relevant empirical research. At the end of this paper, the author looks forward to the evaluation and design optimization of urban road network from the angle of view of complex network based on the research results of urban road network complexity.
