[sustran] Sustainable transport - "Self-containment"

[Alan P Howes]

(Please feel free to post on to any more appropriate lists)

We are currently doing some work in the Arabian Gulf, connected with a
new transport hub and city development - planned population c. 1m.

The aim is that the city, and its main neighbourhoods, would be
"self-contained" as far as possible - i.e. minimising travel between
the neighbourhoods, and between the city and adjacent cities, so
reducing loading on the strategic road network (various plans for PT
too).

Which raises a few questions, for instance - 

- How do you measure "self-containment"?  Presumably a measure would
need to include trip lengths and, I think, a measure of urban
development density.  (For low-density cities, you could have fairly
long trip lengths and still consider there to be a high degree of
self-containment.  But high densities are obviously preferable to
minimise traffic generation.)

- Are there any good case studies of self-contained cities /
neighbourhoods - particularly in places like the Gulf?

- or examples where it has been tried, and failed?

And no doubt I will think of some more - but any input welcome.
