You'd probably need a relation to assign each stop sign to the street.
This seems like a lot of work for something so common.
no, you wouldn't need any relation and would give the work over to the router.
While I agree completely at avoiding relations, that's a hard task for
the router.
It's extremly much work to take in account data combined with the data
you need only via the coordinates as source.
For a stop sign I would add these as node at the street, as it's
proposed - and without tagging the direction it has to be considered.
With this approach a router has to calculate what direction the sign
applies, but the street is known.
Tagging the street sign (with pole and painted metal plate) is also a
good idea - it's a barrier for pedestrian, a pole where a cyclist can
lock his bike perhaps and much else; but it's not useful for routing as
the preprocessing is very expensive.
