[Tagging] Marking dual carriageways

I am thinking about marking tagging roads with separate carriageways. I
want to create map with oneway roads, but in OSM data roads with separate
carriageways that are not oneway are frequently represented as separate
ways, both tagged as oneway.
Adding tag that that would describe way as part of dual carriageway, with
twin road leading in opposite direction would allow to solve this problem.
I am currently thinking about good name for this tag and whatever there is
possibly to achieve this result solely by processing OSM data (processing
is probably necessary anyway to catch cases like
https://www.openstreetmap.org/way/182138211 ).
