Fig. 7: Visualization results of the association between two public transport operational events and regional passenger flow dynamics.

a shows the railway departure event, and b shows the metro train arrival event. Scatterplot of correlation strength of passenger flow fluctuations versus network distance from the event area. c, d show the distance and strength of association of the region with railway train ticket gates and metro exit lanes, respectively. Distance and correlation data are normalized separately in order to keep the indicators on the same scale.
