Isn't it because the way in OSM is cut at the region border, so we get a tower node by definition? If one wants to avoid that, you would have...

I proposed such a merging algorithm several years ago (I'd say 4-5 years ago). I had a working prototype. I remember that the number of reduced edges was not that...

Ah, I was able to find it: https://github.com/graphhopper/graphhopper/issues/69#issuecomment-279610098 Here is the link to the commit: https://github.com/boldtrn/graphhopper/commit/362bea4d015b9973f17aae920f45a30a205be6b2 I didn't actually contracted anything, I just hacked a counter that counts how many...

It always bothered me in OSM if ways are split without a good reason, and I merged quite few over the years by hand :). So I do have a...

> Streets which are crossing country borders will very likely differ in tags and shouldn't be merged For major roads crossing a country this is probably not an issue. But...

AFAIK the main problem is that when a client cancels the request, the client doesn't notify the server. The client will just reject the reply from the server. So the...

BTW: I still think that access=destination for motor_vehicles on tracks in Germany is the correct tagging and follows the OSM wiki: https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions#Germany

In my experience most highway=tracks in Germany are not accessible by motor_vehicles (access=agricultural or access=forestry). Most of the "Feldwege" that are legal to drive do connect to some hamlet or...

Oh no, that's really unfortunate. I guess there will be multiple comments like this in the MapMatching Repo?
