发布时间：2018-10-29 10:16
【摘要】：交通网络节点重要度研究具有很强的实际意义和运用价值,以往的研究主要集中在找出关键交通网络节点后对其加强保护从而在投入资源相同的情况下更大程度上保障交通网络的顺畅运行,当重大自然灾害或恐怖袭击发生时,从关键节点入手帮助交通网络主体功能的迅速恢复。而本文则在结合交通网络实际特征的基础上创新交通网络节点重要度理论的运用方式,将其运用扩展到评估交通网络的好坏,帮助对大型工程项目进行选址等领域解决实际问题,极大地发展了其运用价值,为交通领域的专家和学者提供了一个新的视角和使用工具。由于交通网络是典型的复杂网络,而且是由道路网络和出行网络组成的双层复杂网络,因此本文首先详细介绍了复杂网络的相关理论以及节点重要度的研究方法,系统阐述了道路网络和出行网络的相关知识并辩证分析了二者之间的关系,即道路网络的结构形态会影响到居民出行路径的选择,而居民的出行也会反馈影响道路网络的布局形式,二者之间相互影响,相互促进,不断向更加协调的形式发展。然后回顾了两种交通网络节点重要度传统评估模型,并深入分析了两种模型优缺点,在吸取其经验教训的情况下联系交通网络的实际特征,采用复杂网络的系统科学分析方法即通过删除某个交通网络节点后交通网络的总时间花费变化情况来对交通网络节点的重要度进行评估,构造了交通网络总时间花费评估模型,给出了算法步骤,并运用到实例中进行了演算。最后基于交通网络节点重要度理论提出了交通网络节点重要度均衡度的概念,一个好的交通网络应该没有承载交通量过大容易造成拥堵的过于重要的节点,也少有交通资源不能充分发挥其功能造成资源浪费的过于不重要的节点,而是呈现出交通网络节点重要度大致均衡的状态。并以此为标准以实例的形式对交通网络的性能进行评估以及为大型工程项目的选址提供理论依据。
[Abstract]:The research on the importance of traffic network nodes is of great practical significance and practical value. Previous studies have focused on strengthening the protection of key traffic network nodes after finding them, so as to ensure the smooth operation of the transportation network to a greater extent when major natural disasters or terrorist attacks occur. From the key nodes to help the rapid recovery of the main function of the traffic network. On the basis of combining the actual characteristics of traffic network, this paper innovates the application mode of traffic network node importance theory, and extends its application to evaluate the quality of traffic network. It helps to solve practical problems in the field of site selection of large engineering projects, greatly develops its application value, and provides a new perspective and tool for experts and scholars in the field of transportation. Because traffic network is a typical complex network, and it is a double-layer complex network composed of road network and trip network, this paper firstly introduces the related theory of complex network and the research method of node importance in detail. This paper systematically expounds the related knowledge of road network and trip network, and dialectically analyzes the relationship between them, that is, the structure of road network will affect the choice of travel path of residents. The residents' travel will also influence the layout of the road network, and the two influence each other, promote each other, and continue to develop in a more coordinated form. Then it reviews two traditional evaluation models of traffic network node importance, and analyzes the advantages and disadvantages of the two models in depth, and links the actual characteristics of the traffic network with the experience and lessons learned from the two models. The system scientific analysis method of complex network is used to evaluate the importance of traffic network nodes by deleting the total time cost of a traffic network node, and a total time cost evaluation model of traffic network is constructed. The algorithm steps are given and applied to an example. Finally, based on the theory of importance degree of traffic network node, the concept of importance balance degree of traffic network node is proposed. A good traffic network should not carry too much traffic volume, which is easy to cause traffic congestion too important nodes. It is also rare that the traffic resource can not give full play to its function, which results in the waste of resources, but the status of the importance degree of the traffic network node is approximately balanced. It is used as a standard to evaluate the performance of transportation network in the form of examples and to provide theoretical basis for the location of large engineering projects.
