This future is built, as we will learn here, on a dual view of mobility: on the one hand, practices relating to proximity; and on the other, a plethora of sustainable mobility solutions. After a century of damaging urban disintegration, we are once again learning that proximity is the central point of our urban lives. It also generates strong demand and a vital level of governance, and may potentially offer a solution to the congestion and saturation issues all too familiar in our towns and their traffic. It brings with it the promise of new, calmer mobility solutions; provided we are able to take control of the big issue of transport modes, their combinations, their functions, their scales, and the forces that drive a town; people, resources, information… and therefore data. All of these movements show a trend towards carbon-free mobility solutions as an urgent response to climate changes which negatively affect us all.
