Future Scenarios of Urban Mobility and Their Sustainability

Abstract

At this point in time transportation is a problem in most cities because it fails to achieve the standards of economic and environmental efficiency that would be desirable in the opinion of the experts, as well as for their citizens and institutions. This is true for cities both in the so-called developed and developing worlds even though individual cities have very different levels of mobility supply and performances. Thinking about future urban mobility is thus not only a challenging intellectual exercise, but could provide some insight on what "evolution trajectories" are to be preferred, or avoided, from the social and economic points of view.
