When you honestly look at roads something like a correct hierarchy
always ressembles.

This is why i get to the point "is it a public road" and "a public
road cant be service". If we agree on this you can as some zoom scale
drop service and track.

Because a public road does not branch of a private road. There is
your hierarchy.

So getting back to your example:

R
R
RAAABBBBBBBBBBBB
R  A
R
R
RCCCC
R

If B is a public road A cant be private property and thus not be
a service. If B is a track A can be a service because both
of them share the concept of not beeing for the general public.

Or vice versa. If you make A a service B cant be a public road.
