Figure 4

In the plots a,b,c,d we highlight the road subnetwork underlying the mobility classes 0,1,2,3 (the spatial scale is reported on the left bottom angle). The colored roads are the most used roads for each class according to a ranking distribution, that considers values up two times the standard deviation of the corresponding frequency distribution. We observe that the mobility in the class 0 mainly uses the roads inside the Rimini historical center and along the coast, whereas the subnetwork of class 1 includes the most busy roads in the city of Rimini. The class 2 subnetwork contains the main country roads connecting the cities in the area and the paths of the class 3 are concentrated along the highway that crosses the area
