I see BRouter does not understand restriction:xyz: http://brouter.de/brouter/suspect_scanning_readme.txt, GraphHopper understands it only since 2019. Anyway we shouldn't tag for (a specific) router, so that wouldn't be a good reason to use both schemes, especially because it doesn't really help as there are very many restrictions that only use restriction:hgv anyway.

I'm not sure, does
restriction:hgv=no_left_turn
mean the same as
restriction=no_left_turn
except=bicycle;moped;motorcar;psv
?
That depends on which transportation modes there 'are'. Is all minus bicycle;moped;motorcar;psv the same as hgv? And what would be the advantage of the second scheme, i.e. why use the except list when restriction:hgv already expresses what we need?
Also this kind of tagging seems very rare. This overpass query: `relation["restriction"]["restriction:hgv"];` only yields 14 (!) matches. IMO using restriction + restriction:xyz should be avoided, or at least I am trying to find out if there is any reason to use it.

Why did you add a restriction tag where there already was a restriction:hgv tag? If the turn is only restricted for hgv, restriction:hgv is sufficient, if the turn is restricted for all vehicles use only the restriction tag, but not both?

This turn restriction seemed fine before this changeset: `restriction:hgv=no_left_turn` means 'no left turns for hgv'. Why did you add an extra 'restriction' with a list of 'except' transportation modes?

It looks like the restriction relation/166650 is missing to- and via-members after your change. Can you fix or delete it?

Irgendwas ist hier glaube ich mit der relation/103243 kaputt gegangen. Sie hat jetzt nur noch einen member way mit to-Rolle. Es fehlen die from- und via-member.

Yes, that does not look very accurate, indeed. Honestly, I don't know why it wasn't more precise, but thanks for fixing it in the meantime.

Der Grund dass ich frage ist übrigens, dass wir das highway=ford tag in GraphHopper nicht mehr berücksichtigen werden, s. hier: https://github.com/graphhopper/graphhopper/pull/2538#issuecomment-1067272330

Hi @fkv,

mittlerweile gibt es noch genau 36 `highway=ford` tags. Davon sind 34 hier in der Gegend. Das tag ist (mittlerweile?) auch auf der Wikiseite deprecated: ford=*

Wenn `ford=yes` (noch) nicht in allen Karten gerendert wird, wäre es nicht richtiger das bei den Kartenrenderern zu ändern? Und wegen dem Problem dass eine Furt doppelt gerendert wird, wäre das nicht auch behoben wenn es einfach nur noch `ford=yes` gäbe?
