This why the original intention was that lanes was equal to the number of running lanes on the physical way. In your case it would be lanes=1 except (if you like) at passing places where lanes=2. Since a passing place is a very short length normally it would be simpler to tag a node with lanes=2 at each passing place. Isn't that the simplest method and easily understandable in the data?
