all big cities should have to think of the excess of vehicle movement that is not productive but impairs on those that live in the city. By re-localising and bringing together all the workers and residents in each neighbourhood, with their own commons at the centre and weekly assembly meetings practising participatory democracy, big steps can be taken towards implementing the kind of circular economics, with zero waste, that the world so urgently needs.
Separating pedestrian from vehicular traffic is a basic requirement. One way this can be achieved is using main bus routes to define new communities. Within that border selected roads can be made traffic-free in such a way as allows all within the boundary to reach the central commons without encountering a single car, truck or bus.
