The probability density function P(x, y) for users with different radius of gyration: (a) 1–10 km; (b) 10–100 km; (c) 100–500 km; (d) > 500 km.
Directed motion initially increases with r g, mainly influenced by road usage, yet motion patterns become more diffusive for large distances with the increased use of air travel.
