Hi, there seems to be some inconsistency, how to tag a traffic zone with maximum speed limited to 30 km/h (German "Tempo-30-Zone"). [1]
Tagwatch has the following tags for Europe (with maxspeed=30): [2] usages tag ------ --- 944 zone:maxspeed=DE:30 631 zone:traffic=DE:30 516 source:maxspeed=traffic_zone 433 source:maxspeed=DE:zone30 152 zone:speed=30 140 maxspeed:zone=yes 40 source:maxspeed=zone30 People have been very creative because there is no proposal or definite suggestion on the wiki. The only one that is remotely documented is the first from the list. [3] Lets pick one and add it as tagging suggestion to the wiki pages "Key:source:maxspeed" and "DE:Road_Signs"! [4,5] So which one to choose? Certainly there is no reason to have more than one tag for this. On the one hand, the single most important reason to tag this, is to have a source for the maxspeed value. This would suggest to use the 3rd or 4th. On the other hand, the direct approach would be to tag what is actually there (the traffic zone) and have source:maxspeed implied. There could also be some legal implications, although for Germany, I don't know anything relevant.
