Abstract
We discuss an exponential law for the trajectories distribution in a urban road network, that has been found analyzing a large set of GPS data on private cars dynamics. This law appears to be common for very di®erent cities, from the size of a town to that of a metropolis.We propose to explain this behavior as an effect of the activities sprawling in modern cities, associated with the existence of a cognitive proximity concept that determines the citizens mobility requests We discuss the relevance of these results for a complex systems approach to urban mobility.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
