I think it's time to switch to the tagging list ! The tagging scheme that seems preferred in this discussion is the following :
- simple named junctions : use junction=yes and name=* - complex named junctions with several lanes crossing a different points : two propositions : - use a relation { type=junction, name=*, junction role,...} referencing all the crossing points between the lanes - use a place { tag=junction or crossroads, name=* } on a area englobing the crossing points All right ? What are your opinions on this ? Vlad.
