Figure 6

The histograms show the Complementary Cumulative Distributions of the path lengths for the mobility from the inland to the coastal area (the plots a,b,c refer to the classes 0,1,2 respectively). The activity frequency is reported on the left axis: the small fluctuations in the curve are consequence of the path length discretization. The blue dotted curves give the empirical increase of the Euclidean distance (right vertical axis) from the initial point and the real path length averaged on the paths in the corresponding bin. An interpolation by a straight line is proposed, whose angular coefficient is the sinuosity reported in Table 2
