Smart & sustainable mobility in a complex urban context

The resistance to urban sprawl, the energy and social limits linked to the culture of acceleration and the aging of urban populations change the context and frameworks of thought about metropolitan mobility. In this context, and considering the impact of information technologies and sustainable concern, we propose a hypothesis for the city of the XXI st century as the "city of convergence", with the help of connectivity and shared intelligence. Mobility is our main point of consideration to understand these transformations. To reach and figure the complexity of urban context, we need to consider the urban territory in terms of strata or layers: ground, infrastructures, social networks and information. Within the double principle of convergence (input) and co-operation (output), we associate two questions for a hypothesis concerning livable city. How can public space remain friendly and interactive? Could walking become a new value and a collective urban intelligence for mobility?
