I would prefer directional roles, because you can't always determine the
signed directions programmatically.  I've seen quite a few roads which
could be either north/south or east/west depending on how and where you
look at them.  I've also seen roads that predominantly go in a particular
direction but which are signed the other way by the entity maintaining
them.

The tagging should match what the signs on the ground say.
