Recent studies have pointed out the complexity of human mobility and the necessity of understanding the individual mobility demand to perform a mobility governance. In Italy a relevant percentage of vehicle population is equipped by a GPS system for insurance reason and the origin and destination of each trip is recorded in a data base. We have analyzed the GPS data of the whole Emilia-Romanga region recorder during the November 2008 to look for generic scaling laws that characterize human mobility. We propose the existence of an "mobility energy" that determines the trip length distribution. We also reconstruct the mobility network from experimental data and we show as the mobility demand is a mixed of an origin-destination systematic mobility and a random asystematic mobility which produces a diffusion behavior in the network. We finally consider the possibility of classifying the different individuals according to the properties of their mobility networks.
Prof. Bazzani is member of the group of Physics of Complex Systems (www.physycom.unibo.it) at the Physics Department of the Bologna University and he coordinates some research projects in the Physics of the City Laboratory. He is responsible of the INFN theory project BO41 on physical applications of dynamical systems theory. The main research interests of Prof. Bazzani concern the study of dynamical models relevant for social and biological systems., among others, the applications of dynamical systems theory to neuronal networks and evolution models, and the emergent properties of an automata gas (i.e. a statistical systems of cognitive particles) studied for the applications to modeling urban mobility.
