I'm forwarding here the reply from Peter Miller, ITO World: ============================================
Personally I find the suggestion of total_tracks reasonably appealing initially, however it would have to be repeated across all the tracks which seems ugly and still doesn't say with confidence which tracks are connected. The relation approach is clearer and makes it absolutely clear which tracks are being grouped but the relation may not however be the same one as the route relation which makes it difficult. An automated approach would involve merging all close tracks and figuring it out. Not trivial but quite computable in my view. The result could then be converted into relations and a bot process could put it all back into osm, however some people don't like bots!. No obvious answers unfortunately. Personally I thing relations and some bot assistance in due course would be best. A final thought is the dual carriageways and their interchanges share some of these issues.
