[OSM-talk-be] Destination tagging on motorways

[Marc Gemis]

Hallo Martijn,

I just picked a random exit node http://www.openstreetmap.org/node/31247369

it has the following tags:

exit_to=Turnhout, Kasterlee
highway=motorway_junction
name=Turnhout-Centrum
ref=24

Unfortunately, this is not typical for Belgium. I also checked some
junctions around Antwerp (http://overpass-turbo.eu/s/5bG ) , none of them
has an "exit_to".  The name and ref are what we use for all our exits. They
all have a number and a name.
During my lanes/turn:lanes editing in Flandres, I've encountered a handful
of cases where there is a destination on the motorway_link (the exit).

Furthermore we do not have a lot of "destination" tags, that is why Johan
proposed to help us, based on some images he took. He would tag the
destinations as in The Netherlands, so with a destination and
destination:ref tag. Perhaps even with the destination:symbol extension.

André's example was for an entrance to a motorway, not an exit (if I'm not
mistaken). I assume we have even less (destination) data there.


None of the keys is used really much:
http://taginfo.openstreetmap.org/compare/destination/destination:forward/destination:backward/exit_to
but based on the fact that there is some growing support for destination in
the US (pushed by you guys I understand), I would prefer to use destination.

regards
