Research on evaluation algorithm of key nodes in urban road traffic network based on complex network

Abstract

Abstract Urban road traffic planning is a complicated project. If this project is abstracted as a complex network, the smoothness of important nodes in the network will have a significant impact on the smooth flow of the entire city. How to evaluate the importance of urban road traffic network nodes optimizing key nodes as much as possible is the key to transportation planning. This paper proposes a complex network node “structural hole” impact matrix to evaluate key nodes, constructs key node evaluation criteria, and simulates and analyses smaller-scale networks. The results show that this method can accurately and effectively evaluate the criticality of nodes. The use of its research results can provide a decision basis for alleviating the current urban traffic congestion.
