[Tagging] Understanding links

one way unclassified roads?) that lead onto the actual new trunk road.

There is not much documentation on the wiki. The only thing that I found
was a statement at http://wiki.openstreetmap.org/wiki/Tag:highway%3Dservice
that says that highway=service is wrong, but everything else is okay.

I agree that *_link is not good. (Also because you can often use the
frontage road with smaller/slower cars than the main road.)

As frontage roads are quite common in some countries, I think it would be
useful to create a wiki page with some documentation and a best practice
guide.

Proposal for the content:

– frontage roads are never highway=*_link nor highway=service
– frontage roads have usually a lower level than the main road (which one
is up to the mapper to decide)

Example: If the main road is secondary, the frontage road must be one of
“tertiary” or “unclassified” or “residential”.

Could this be a useful guide?
