The automobile system and transport models: Developments towards planning future mobility

By Patricia Sajous, Paul Salze, Valérie Bailly-Hascoët


This article is based on a multidisciplinary study (law, geography, computer science) developed in the Mobility part of the European research program XTERM (complex systems, territorial intelligence, mobility). At the crossroads of these three approaches, we question the place and the future of the automobile in France at a time of a desired transition towards sustainable mobility (collective, individual, shared). An analysis of past and current modelling practices shows that everything seems to be thought out by and for the automobile. Recent legislative developments are characterised by the integration of the car into the overall organisation of transport, where the user is replaced by a homo mobilis with a wide modal choice. Through the question of the embodiment of transport systems, we study a little-explored aspect of day-to-day trade-offs that will need to be discussed with regard to regulations. At the end of the article, we present proposals, tested during the project, for a theoretical and methodological renewal in modelling.
