Establishment and Analysis of the Supernetwork Model for Nanjing Metro Transportation System

الملخص EN

In recent years, many researchers have applied complex network theory to urban public transport network to construct complex network and analyze its network performance.

The original analysis method generally uses the Space L and Space R model to establish a simple link between public sites but ignores the organic link between the overall network system and the line subsystem.

As an important part of urban public transport system, subway plays an important role in alleviating traffic pressure.

In this paper, a supernetwork model of Nanjing metro network is established by using the supernetwork method.

Three parameters, node-hyperedge degree, hyperedge-node degree, and hyperedge degree, are proposed to describe the model.

The model is compared with the traditional Space L and Space P models.

The study on the supernetwork model of Nanjing metro complex network shows that the network density, network centrality, and network clustering coefficient are large, and the average network distance is small, which meets the requirements of traffic planning and design.

In this study, the subway line is considered as a subsystem and further simplified as a node, so that the complex network analysis method can be applied to the new supernetwork model, expanding the thinking of complex network research.
