Document Summary
From dispersion to recentralization: can planning redefine urban. There are two clashing urban forms; dispersion and recentralisation. Dispersion is the predominant form, there is relatively low density and rigid land use specialisation. It is easy to plan, a concept pieced together in the post war years. There is full adaptation of land uses to a generalised use of automobile. Activities are separated due to the space devoted to cars. Cars give more accessibility, which allows development to spread out. Many people have an interest vested in this kind of development such as car manufacturers because it depends on cars. Flattening of accessibility gradients, favourable to transition from centralization to dispersion. This urban form has some issues; environmental consequences due to car use, energy, quality of life (congestion), health (people mostly have a sedentary lifestyle), infrastructure costs to spread roads and pipes for e. g. , and standardised development.
