[Talk-us] Relation roles: Clockwise and Counterclockwise route directions? (e.g. Pittsburgh's Belts)

I know that north/south/east/west directions are preferred for relation roles of one-way route segments (e.g. one-way pairs or divided highways), but what about clockwise and counterclockwise? Often beltways, like D.C.'s Capital Beltway, are signed such that they abruptly go from north/south to east/west, but then you have routes like Pittsburgh's Belt System, where the Belts aren't signed with directions at all. These seem to be given "CW" (clockwise) and "CCW" (counterclockwise) roles. Is this correct, or does "forward" or some other role need to be used?
