As with other routing signs, yes, the routing software should be able to 
determine that, as long as the ways are properly marked.

So, I have the opposite opinion from Paul. I don't think routing signs 
should be marked. But, until such time as the amenities at an exit can all 
be mapped as POIs, I think a way of denoting what amenities are available 
at a particular exit would be helpful to a map user.

I do think this should only be an interim step (such as [oh, no, I 
shouldn't bring up interpolation!]), but I think it is an appropriate 
interim step. The "how to" is the question. Creating a relation between an 
exit ramp and a list of amenities is an option. The list doesn't have to 
be called a road sign, and doesn't have to be mapped. It could just be 
called an "amenities_list". Then, once the amenities are all mapped, the 
relation can be deleted, if desired.
