Gravity model in the Korean highway

Abstract: 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 2 ij , 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 homogeneou… Show more

“…Geographical distance is considered to be one of the realistic factors that affect the existence of nodes' interactions in networks [140]. Especially it plays very important role in analyzing transportation networks [141,142]. It is known to be relevant to the existence of an airline, and the number of airlines decays with the increasing of corresponding distance [55,143].…”

“…Universal phenomena also occur in many other social complex systems where regularities arise despite the complexity of the human interactions and the spatiotemporal dynamics (34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47). Stemming from the simplicity of the assumptions, the stochastic model developed in this paper could conceivably apply elsewhere in society, such as the duration of both platonic and romantic friendships.…”
