>The idea is that with a 30 driving rules list applying to an agglomération
If it's just the traffic rules urban vs. rural, there's the tag (with 37 000+ uses) zone:traffic=**:rural zone:traffic=**:urban where ** is the two letter country code. Don't count on anything ever deriving the rules (like maxspeed) from that tag, so tag the maxspeed anyway. If, on the other hand, it's about the area that is considered "agglomerated", irrespective of the (not) implied traffic rules, there are probably/apparently different rules in every country for calculating the area, for example by buffering all residential buildings and combining the area formed by that operation. -- Alv _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
