I can tell you jack that they are 2-way roads, since I'm the one who's
put them in there. 

Let me explain the reasoning behind my use of those tags (which upon
reflection and the comment by Stuart earlier made me realise I've done
it wrong, for which I apologise).

I use JOSM to edit the maps and I have the validator turned on. This
causes those little bits of road to come us as invalid because they
don't have a name. So I went looking for a way put the cross overs in
those cases without having to enter the road name all the time (It just
seemed redundant to enter the name of the road to shut up the validator
for the sake of a few turn lanes.) I saw the motorway_link
and primary_link entries which talk about 'slip lanes' to enter/exits
roads, which seemed to fit for these cases. AT NO POINT in the easily
accessible (or anywhere I've so far found) portions of the Wiki does it
make it clear that those lanes are one way, so I assumed they just
covered general entry/access road pieces.

So my question therefore becomes what DO you tag these roads with?????

I've found roads of secondary, tertiary and residential categories that
effectively have _link level turn lanes in addition to central turning
lanes. In the case of tertiary and residential I've just using the
normal tags for all of them (and having to put the name of the road in
on every case to shut up the validator & map lint) although I might
have snuck a tertiary_link or two in around the place to be honest :)
