I tagged noexit=yes on the ways. Why ? If I remember correctly some more experienced mapper told me it was ok to do so. And perhaps I read the wiki page before June 28, 2011, when there was nothing mentioned about way or node.
You cannot assume each mapper reads all wiki pages every week or follow the tagging mailing list to keep up-to-date with the changing definitions of tags. Another reason is that, as Pieren pointed out, many features are mapped on the way, not on a single point. And yet another reason is that the OSM definition is different from the traffic code definition, where noexit is placed on each street where cars cannot leave the street via another exit. So people might just tag it without reading the wiki at all. The tag info on the wiki page shows enough usages on ways to make it a viable tagging method. Enough reasons why people might tag this incorrectly according to the current wiki definition ? :-) regards m On Tue, Apr 8, 2014 at 12:57 PM, fly <lowfligh...@googlemail.com> wrote: > On 08.04.2014 12:10, Pieren wrote: > > On Sun, Apr 6, 2014 at 3:48 AM, fly <lowfligh...@googlemail.com> wrote: > > >> noexit=yes has nothing in common with the traffic_sign as: > >> > >> 1. it only is about motorized traffic where noexit=yes is about every > >> travel mode. > >> 2. it is used at the beginning of a cul-de-sac and an information for > >> driver of motorized vehicles where noexit=yes is always tagged on the > >> end node of a way without any connection and is a hint for mappers and > >> QA tools. > >> > >> Please, do not mix it up. > > > > Please, return to earth.
