Today the idea of ‘mixed use’ is one of the leading policies in the urban (re)development of many European cities. UN Habitat recently indicated that: ‘. . . cities have a natural advantage when it comes to promoting low-carbon mobility. Their density and mixed use ensure that many destinations can easily be reached on foot, by bike or using public transport.’ From this we can define mixed-use neighbourhoods as those that interweave a diversity of urban activities within a walkable distance, thus in spatial proximity. Which urban configurational conditions afford a mixed-use city?
