Road Traffic and Community Severance

A long time ago I first came across the concept of community severance, caused primarily by the increase in road traffic. The idea is that cars moving through a street will separate people on that street- primarily because people will not cross the road...

Anyway, I saw this and thought it was interesting. I think I have seen Alan Stanton mention Donald Applyard's Liveable Streets concept, this article looks at this in a short video film.
