hi,

The proposed OSM default tags (e.g. for per-country speed restrictions 
based on highway type) were discussed on this forum before. These defaults 
also allow access restrictions to be set 
(https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions). 
This could be useful to indicate that "trunk" roads in about half of the 
countries are not accessible to cyclists and pedestrians (e.g. France, 
Germany), and in the other half they are (UK, USA, ...). But I wonder: *does 
osmand look at these default tags?* Either during map conversion or 
internally...

The background of my question is this: When I'm cycling in France and using 
a "shortest routes" profile, osmand sometimes wants to send me over a trunk 
road if this saves a lot of kilometers. Like in most of western Europe, the 
things that are tagged as trunk roads here are very much like motorways. 
Cycling on them is strictly prohibited and very dangerous. Even a "shortest 
routes" navigation profile should not allow this (maybe an "outlaw" profile 
would do). In Germany or the Netherlands trunk roads are systematically 
tagged with "motorroad" or "access:bicycle=no". In France this is not the 
case. When I started adding such tags in strategic places, I've been told 
it was redundant, because navigation apps should take the national rules or 
the proposed Defaults into account. It sounds indeed like a neat solution 
to me.

Of course I adapted my routing profile already: I replaced the useless 
"allow motorways" switch by an "allow trunk roads", which I might flip on 
in Tasmania or so.

Best regards,

Mark
