Related to this, I also wanted to look for some ideas on how to
generate names for the unnamed ramps in an OSM extract.
Most ramps in parts of the US I've traveled don't have name. What they
do have is destinations, which indicate the information on the signs.
Incidentally, the Ohio Department of Transportation does post a blue
sign on every highway ramp, bearing a heavily abbreviated (devowelized,
actually) name of the ramp, for example:
Ramp
E 275
To
N 75
or:
Ramp
E 275
To
Lvldmdra
In cases where the ramp belongs to multiplexed routes, you may see
multiple ramp name signs side by side: <http://www.roadfan.com/3bluemrk.JPG>
These signs are specifically intended to help motorists pinpoint their
location when calling for help. (If emergency responders look for the
wrong ramp in a given junction, they might end up wasting precious
minutes trying to circle back.)
I've been hesitant to put these names in the `name` tag because they
clutter up ordinary use cases like map display and navigation. I'm
inclined to use `official_name` here and expand all abbreviations (per
OSM convention).
