Construction Rules of Urban Rail Transit Network Based on Complex Network Eigenvalue

With the rapid development of economy, the problem of urban traffic congestion becomes more and more serious. Urban rail transit, with its fast speed, large carrying capacity, environmental protection, and energy saving, starts to play an increasingly important role in the urban transportation system. However, due to the large scale of urban rail transit construction, high investment, reconstruction difficulties, and other deficiencies, it is particularly important to explore the rules of urban rail transit network construction. Based on the complex network theory, this paper studies the rules of urban rail transit network construction in Shanghai. Firstly, the degree and degree distribution, shortest path, clustering coefficient, median, and other characteristic values of Shanghai urban rail transit network are calculated by using Pajek software. Then, the graph analysis of the data was carried out, which objectively showed the changes of characteristic values of each network in the development process of Shanghai urban rail transit, and drew the conclusion that Shanghai urban rail transit line network was a scale-free network. Finally, based on the research results of this paper, this paper puts forward three Suggestions for the cities that are planning or planning the urban rail transit network, and provides auxiliary decision-making for the planning of the front-line network.
