This is the main point here I think: administrative classification is
about ownership and maintenance of the road. Of course there also is a
link between administrative classification and importance of
connection, but planning norms and regulations usually deal with the
"importance of connection". In general this classification corresponds
also to administration classification, but not in all cases. In the
end for our scope the importance of the connection is way more
interesting than who pays the maintenance.
