It looks good to me, except for the last example of a "turning loop" as I've been calling it. We're going to have the same problem with this one, because they are abundant and very small, thus people will likely mis-tag it rather than drawing a tiny loop. When I fixed up some of westendguy's mini_roundabouts, he often used the tag with these cul-de-sac turning loops, and I tagged it as junction=roundabout and note=turning_loop so it could be checked/fixed later. Checking taginfo, someone else tagged these as highway=turning_circle with a FIXME [1]. Others have indicated they do highway=turning_circle and traffic_calming=island. The first question is if these can be considered a roundabout if there is at least one driveway that connects to it (this would be my choice), as is most often the case. If not, then we need some way to differentiate these from highway=turning_circle and junction=roundabout, though I'm not sure what tag is best. -Josh [1]: http://taginfo.openstreetmap.org/tags/FIXME=Not%20a%20true%20%22turning_circle%22%20because%20of%20an%20island%20in%20the%20middle.%20Needs%20to%20be%20drawn%20completely. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
