Figure 9From: Identifying the most influential roads based on traffic correlation networksStatistics of the mean impact distance of nodes. (a) PDF of mean impact distance at RH1 (red circles), NT1 (blue crosses), and RH2 (green squares). (b) Mean impact distance (in km) during NT1 VS during RH1. (c) Mean impact distance during NT1 VS during RH2. (d) Mean impact distance during RH2 VS during RH1. The data is during 26–30 Oct. 2015, \(N=4530\), \(L=900\), and \(\tau _{\mathrm{max}}=150\). Pearson’s correlation: (b) 0.7463, (c) 0.6926, (d) 0.6402Back to article page
