I'm sure that others will come in on this one. <warning of impending over-
simplification - sensitive readers may wish to skip the rest of this

analysis, is suited to modelling movement in public squares, where people
are moving around the space in 2 dimensions. Axial maps, as a 1D analysis,
are suited to modelling movement along streets, where people are
predominantly moving through the space in 1 dimension.
I look forward to putting everything into a multiple regression analysis
[MRA] and seeing what comes out.

Hmm, tricky one to stick into an MRA. I guess we'll try various types of
dummy variable, and see what comes out. All suggestions welcome - the
first things that come to mind are a 0/1 indicator for presence or absence
of retail, or a metric for closeness to some perfect mix of retail,
employment, housing. This perfect mix would optimise the availability of
the first two from any given dwelling.
