We investigate the traffic flows of the Korean highway system, which contains both public and private transportation information. We find that the traffic flow T ij between city i and j forms a gravity model, the metaphor of physical gravity as described in Newton's law of gravity, P i P j / r ij 2 , where P i represents the population of city i and r ij 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.
