Hi Djakk,
Interesting approach, which might work for Europe, but at the moment I
am not entirely convinced. What is strategic at a European level might
not be so strategic locally, and vice versa. The European numbers are
also not signposted everywhere, so there may be a challenge of
verifiability. I believe the European definition basically defines the
endpoints and a few waypoints, and it is left to national authorities to
join the dots as they wish. So it may or may not achieve your goal of
having a harmonised definition between countries.
Are you actually sure there is a problem to be solved? Do you have
examples of inappropriate or inconsistent use of highway=trunk?
