[GraphHopper] Speed indication

Hello,

I am a bit confused about the indication of the allowed speed on an edge.
I want to tell the user of my navigation software what the max speed on the
current edge is. If i take the speed value from an edge itself (in
graphhopper), it tells me some average value defined in the CarFlagEncoder.
This is ok for routing purposes but not for max speed indication. Next
thing is that i would have to find out in which country an edge is located
to take the allowed speed according to this country.
For instance: in italy the speed limit on tertiary and main roads is 90km/h
not 100km/h like in Germany.

Is there a way to solve this? Does OpenStreetMap even provide such
information?

Thanks.
