4.2.3. Clustering Coefficient

For the bus station network, the clustering coefficient reflects the intensity of the bus lines near each station, and the network is analyzed. The average clustering coefficient of the bus station network in Xi'an is *C* = 0.223, and the low clustering coefficient indicates less neighbor node connection. Therefore, when the traffic flow of neighbor nodes passes through the node, it is easy to cause the node to be heavily loaded and congested. Figure 3 presents the clustering coefficient value of different nodes.
