I think you got me wrong, of course you have to connect the pedestrian
area to the road. What I was trying to explain is, that IMHO you also
have to connect the pedestrian area to adjacent buildings, if there is
no space in between them (because you map an area as is, at least I do
this). Therefore the centre of a road hardly ever can be directly in
the corner of an area.
