Sounds good. I'm not sure what to suggest here. What we have works,
although it may be sub-optimal in some way. I never had a theory on
how sub-divisions should be used and I was kind of suprised that the
first thing I tried seemed to work (this was before routing).

It would probably be better to create a grid of subdivisions and cut
the roads at nodes near the boundary so that there is a lot less
overlapping.  I've no idea how much, if any, difference it would make
though, and it would entail a fairly substantial re-write.
