Human mobility world lines on urban topologies

In this paper we show some urban geometries generated by different human mobility types, in particular car and pedestrian mobility. These dynamical morphologies have been observed in many cities by working the Physics of the City Lab. Here we present two examples of the Torino car mobility network, some pedestrian trajectories in Marseille places, and crowding examples during the Venezia carnival. The pedestrian trajectories have been drawn by one of us, Mariateresa Sartori, a Venetian artist, using many video movies turned in a well defined spacetime framework, performing an artscience project on complex cities from Venezia to Marseille developed by us at IMERA, Marseille (2011–2012). In particular the investigations on walking pointed out which pedestrian world lines in general don’t follow Euclidean straight lines but more complex paths we guess due to the individual free will.
