I have been mapping it as two parallel oneways almost mainly for the purpose
of routing. I have also found that it makes it much easier to follow the
road pattern especially at complicated junctions/interchanges (see

It doesnt make sense to do this for each and every road with a median
though, but only for the arterial thoroughfares.
