Ah, so I was more getting at a style seen in the Netherlands. The residential neighbourhoods have short sections of roads with frequent choke points (sometimes featuring speed bumps, but sometimes just narrowing of the road to a single lane), together with frequent one way sections and blocked routes for cars but continuations for lighter vehicles. From the perspective of a vehicle, the neighbourhood is precisely a pod: disconnected from a neibouring region until they filter from the residential streets onto a more main road and then back into the neigbouring residential area. However, to pedestrians and bicycles, there is no real delineation. Mazelike to vehicles, multiply connected and convenient to pedestrians and bicycles. Edit: so pedestrians and bicycles will typically avoid the choke points since more direct routes are available to them. On the main roads where vehicles become congested (and faster) clear separation of the traffic types becomes increasingly necessary compared to lazy back streets where bicycles and vehicles can intermix (these people will typically be neighbours anyways).
