Where possible, this will duplicate the sign. The thinking is that sign contents are carefully chosen for maximum clarity to drivers, and to distinguish them from nearby exits. That will not necessarily be the nearest main road the exit leads to. The Wiki would have the exit node as
ref=20A
name=
exit_to=HI 63 North; Likelike Hwy
(Exit Only optional also, I suppose)
Ok, that makes sense. I am thinking of the case where a GPS provider or directions provider uses our data and wants to have "Take exit 20A towards HI 63 North Likelike Hwy" on the screen or spoken via TTS.
With that in mind I think it's important that the exit_to tag only include verbage on the sign (and not stuff we make up).
IMO, not all the verbage on the sign. I've been tagging name as the name of the exit according to the relevant authority (e.g. CalTrans in CA). I accept that people now want to change this to use exit_to instead of name. However, some exit signs also have destination information, like the name of the city or local tourist attraction. This secondary information I've been putting in a towards tag. I would also like to separate the name into a root and a directional component. e.g.
Signed:
Exit 19
[SR2 shield] South
Los Angeles
Tagged:
ref=19
exit_to=CA-2
exit_to_dir=South
towards=Los Angeles
Signed:
Exit 54
Mountain Avenue
Mount Baldy
Tagged:
ref=54
exit_to=Mountain Avenue
towards=Mount Baldy
NE2 seems to have already jumped ahead with http://www.openstreetmap.org/browse/changeset/7787398 - "change name to exit_to and speed limits to mph". Perhaps he can comment on exactly what he did so I know what I have left to do in SoCal, where I've been the primary tagger of on/offramps.
How do we ask the renderers to recognize the new schema?
Also, JOSM should have the ability to concatenate ref, exit_to, exit_to_dir, and towards (currently, you can just pick one via mappaint.nameOrder).
