We investigate the traffic flows of the Korean highway system, which contains both public and private transportation information. We find that the traffic flow Tij between city i and j forms a gravity model, the metaphor of physical gravity as described in Newton's law of gravity, PiPj/rij2, where Pi represents the population of city i and rij the distance between cities i and j. It is also shown that the highway network has a heavy tail even though the road network is a rather uniform and homogeneous one. Compared to the highway network, air and public ground transportation establish inhomogeneous systems and have power law behaviors.

Human mobility: Models and applications (2017, background): “In addition to providing the mathematical framework to model human mobility flows [39, 149, 150], these models have found successful applications in estimating other spatial flows, including cargo shipping volume [151] and social interactions from inter-city phone calls [122, 152].”
Uncovering space-independent communities in spatial networks (2010, background): “It has been shown for systems as diverse as the International Trade Market [16], human migration [17], traﬃc ﬂows [18] or mobile communication between cities [19, 20] that the volume of interaction between distant locations is successfully modeled by where N i measures the importance of location i…”
