Table 4 Spearman correlation coefficients of classic network measures (node degree, closeness, betweenness, and PageRank centrality) to the actual node usage by real-world trajectories (left part of the table) and to the node usage by random trajectories (as introduced in “Modeling trajectories by random walks” section. Starred values indicate a p-value of <0.05
