【摘要】：近年来,随着我国城市化进程的快速发展以及政府对交通的重视及投入,城市公共交通设施越来越完善,但公共交通的发展始终无法缓解城市交通拥堵问题。目前,将城市公共交通系统抽象为复杂网络,相关的拓扑统计量在交通网络中被赋予不同的含义,利用复杂网络理论分析城市各种特性的研究得到了广泛关注。很多学者已经对城市公交网络系统进行了研究,但大部分文献仅仅涉及到它的静态特征以及稳定性分析两方面,大致可以划分为两大类:一类是对交通网络拓扑性质的研究;一类是在拓扑性质研究的基础上,进一步考虑网络的可靠性或鲁棒性与结构优化的研究。在对公共交通进行研究时,随着问题计算复杂性及问题规模的不断扩大,传统的方法遇到了很大的困难,必须从新的视角去探讨城市公交网络的结构特性和动力学性质。所以,若对城市公交网络进行系统的研究,不仅要考察城市公交网络拓扑本身的结构特征,更重要的是通过考虑城市交通本身所具有的动力学特性,从宏观上揭示产生交通拥堵的机理,寻找影响公共交通正常运营以及交通拥堵的原因,为有效地改善道路交通环境提供理论依据。基于上述的讨论,本文将复杂网络的同步理论应用于城市公共交通网络。针对城市公交网络的特征,分别构建了多重边和多重权重城市复杂公交网络模型,重新定义两种网络的一些静态指标及其在交通网络中的含义。研究两种公交网络的自适应同步,并利用其“动态”地研究公共交通系统的一些常用指标,如乘客流量、发车频次等对整个公交网络的影响,从理论上全面系统深入地研究了交通网络系统的内在运行规律和机制。此研究对交通管理部门进行规划、设计和管理具有很大的借鉴意义,进而为缓解交通拥堵、制定阻塞疏导方案,完善交通网络结构和进行有效地交通控制服务。综上所述,本文进行了以下研究与探讨:(1)本文对国内和国外的一些相关文献进行全面分析和总结,对复杂公共交通网络问题的研究成果及研究现状进行剖析,继而指出当前研究存在的弊端和不足,并以此为基础,引出本文研究的主要内容。(2)阐述复杂网络的基本知识和网络特征,深入研究具有时滞以及时变时滞的复杂网络的同步方法,给出其自适应同步的准则。(3)在已有的城市公交网络模型的基础上,构建多重边复杂公交网络模型,重新定义此网络模型的一些静态指标,并提出了新的指标,如方向度和节点强度等,同时赋予它们在交通网络中的含义。(4)建立多重边复杂公交网络模型,并将其拆分为多个单边的子网络,给出在含有时滞以及时变时滞的情况下多重边复杂公交网络的同步准则。利用乘客流量、发车频次等参数对公交网络同步效果的影响,讨论整个多重边复杂公交网络的平衡性,并建立队长消散模型模拟发车频次对乘客滞留时间的影响。(5)考虑复杂网络边上可以存在多个不同性质的权重,令公共交通系统的几个参数作为复杂网络边上不同的权重,构建多重权重复杂公交网络模型并重新定义它的一些静态指标,如点权、点权相似度和边权等。将多重权重复杂公交网络拆分为多个单权重的子网络,给出在含有时滞以及时变时滞的情况下的同步准则。利用其同步效果的不同,讨论公共交通网络的一些参数对整个公交网络平衡的影响。(6)采用一种新的建模方法,对于公共交通中的某个交通枢纽站,以经过此枢纽的不同公交线路作为网络的节点,构建多重权重城市公交枢纽网络模型。在某条公交线路运营失效和增加一条公交线路两种情况下,讨论多重权重复杂公交枢纽网络的平衡性。分别考虑在高峰期和某条公交线路人数突增两情况下,讨论发车频次对整个多重权重复杂公交枢纽网络平衡性的影响。
[Abstract]:In recent years, with the rapid development of the urbanization process in China and the emphasis and input of the government on the traffic, the urban public transport facilities are becoming more and more perfect, but the development of public transport has always been unable to alleviate the problem of urban traffic congestion. At present, the urban public transport system is abstracted as a complex network, the related topological statistics are given different meanings in the traffic network, and the research of various characteristics of the city is analyzed by using the complex network theory. Many scholars have studied the urban public transit network system, but most of the literature is related to the static characteristics and the stability analysis, which can be divided into two main categories: one is the study of the traffic network topological property; In this paper, the reliability or robustness of the network and the research of the structure optimization are further considered on the basis of the study of the topological property. In the study of public transport, with the increasing complexity of the problem and the expansion of the scale of the problem, the traditional method has encountered great difficulties, and it is necessary to explore the structural and dynamic properties of the urban public transit network from a new perspective. Therefore, if the system research of the urban public transit network is carried out, not only the structural characteristics of the urban public transit network topology itself but also the dynamic characteristics of the urban traffic itself are considered, the mechanism of the traffic jam is revealed from the macro level, Find out the causes of the normal operation of public transport and the traffic congestion, and provide the theoretical basis for effectively improving the road traffic environment. Based on the above-mentioned discussion, this paper applies the synchronization theory of the complex network to the urban public transport network. In view of the characteristics of the urban public transit network, the multi-side and multi-weight urban complex bus network model is constructed, and some static indexes of the two networks and their meanings in the traffic network are re-defined. The self-adaptive synchronization of the two public transport networks is studied, and some common indexes of the public transport system, such as the passenger flow rate and the departure frequency, are studied in the 鈥渄ynamic鈥，
