Almost all European tier 4 systems are in the HB now. Some comments to the remaining systems:
beln - Belgium Route Nationale / Gewestwegen 1-599 (michih)
I think I'll complete it this summer. It's painful...
ffopr/frolv - Faroe Islands Primærruter (need more info) (---)
What kind of info do you need, Si? Cinx will go there in September and might check open issues on-site. I guess you are not sure if the routes are really signed (GSV not available)?
grceo - Greece Ethniki Odos (si404)
Started.
itass - Italy Strada Statale (---)
We finally have a
map rusr - Russia Regional Roads (system not fully signed until 2018) (si404)
rusa - Russia Access Roads (system not fully signed until 2018) (si404)
I guess Si will draft the remaining routes in 2018 or once GSV is updated?
turd - Turkey Devlet Yolları (---)
Open. Si, you've once said that it should be not too hard (and not too large?). If you cannot draft it, I might do it later this year or in 2018...
I wanted to complete deul and norfv first but if it would be the last remaining tier 4 system...
