【摘要】：交通網(wǎng)絡節(jié)點重要度研究具有很強的實際意義和運用價值,以往的研究主要集中在找出關鍵交通網(wǎng)絡節(jié)點后對其加強保護從而在投入資源相同的情況下更大程度上保障交通網(wǎng)絡的順暢運行,當重大自然災害或恐怖襲擊發(fā)生時,從關鍵節(jié)點入手幫助交通網(wǎng)絡主體功能的迅速恢復。而本文則在結合交通網(wǎng)絡實際特征的基礎上創(chuàng)新交通網(wǎng)絡節(jié)點重要度理論的運用方式,將其運用擴展到評估交通網(wǎng)絡的好壞,幫助對大型工程項目進行選址等領域解決實際問題,極大地發(fā)展了其運用價值,為交通領域的專家和學者提供了一個新的視角和使用工具。由于交通網(wǎng)絡是典型的復雜網(wǎng)絡,而且是由道路網(wǎng)絡和出行網(wǎng)絡組成的雙層復雜網(wǎng)絡,因此本文首先詳細介紹了復雜網(wǎng)絡的相關理論以及節(jié)點重要度的研究方法,系統(tǒng)闡述了道路網(wǎng)絡和出行網(wǎng)絡的相關知識并辯證分析了二者之間的關系,即道路網(wǎng)絡的結構形態(tài)會影響到居民出行路徑的選擇,而居民的出行也會反饋影響道路網(wǎng)絡的布局形式,二者之間相互影響,相互促進,不斷向更加協(xié)調的形式發(fā)展。然后回顧了兩種交通網(wǎng)絡節(jié)點重要度傳統(tǒng)評估模型,并深入分析了兩種模型優(yōu)缺點,在吸取其經(jīng)驗教訓的情況下聯(lián)系交通網(wǎng)絡的實際特征,采用復雜網(wǎng)絡的系統(tǒng)科學分析方法即通過刪除某個交通網(wǎng)絡節(jié)點后交通網(wǎng)絡的總時間花費變化情況來對交通網(wǎng)絡節(jié)點的重要度進行評估,構造了交通網(wǎng)絡總時間花費評估模型,給出了算法步驟,并運用到實例中進行了演算。最后基于交通網(wǎng)絡節(jié)點重要度理論提出了交通網(wǎng)絡節(jié)點重要度均衡度的概念,一個好的交通網(wǎng)絡應該沒有承載交通量過大容易造成擁堵的過于重要的節(jié)點,也少有交通資源不能充分發(fā)揮其功能造成資源浪費的過于不重要的節(jié)點,而是呈現(xiàn)出交通網(wǎng)絡節(jié)點重要度大致均衡的狀態(tài)。并以此為標準以實例的形式對交通網(wǎng)絡的性能進行評估以及為大型工程項目的選址提供理論依據(jù)。
[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.
