Abstract
Finding influential nodes is of significance to understand and control the spreading capacity of complex systems. This paper aims to find influential nodes of bus networks by a proposed node failure process. Network efficiency and average transfer times are used to measure the performance of bus networks. Six node measures including degree, node strength, line number, betweenness, local triangle centrality (LTC) and a measure considering neighborhood similarity called LSS are introduced to evaluate the importance of nodes. Results show that removing nodes with high betweenness value can effectively decrease the network efficiency, but cannot increase the average transfer times. Furthermore, removing nodes with high values of LTC and LSS considering the neighborhood information can damage the bus networks from the perspectives of both network efficiency and average transfer times.
