Hello, A while ago, I came across the maxspeed:variable=* tag, to specify if a highway's maximum speed could be further reduced using dynamic speed indication. This was proposed back in 2012 as an alternative to maxspeed=signals; the main rationale being that maxspeed=signals does not convey any information regarding the actual maximum speed, which can affect routing decisions, speed warnings and the like.
The original proposal can be found at: http://wiki.openstreetmap.org/wiki/Proposed_features/Dynamic_maxspeed The proposal process was initiated on October 20th, 2012, and from the talk page history (and the archives of this mailing list), many suggestions and improvements were discussed and merged into the proposal. However, the original user behind the proposal (Eckhart Wörner) appears to be no longer active, and the proposal has remained dormant in the RFC stage. However, it appears that this proposal has gained widespread usage and acceptance. Some examples that I've encountered: - taginfo counts 7,748 objects tagged with maxspeed:variable=*, compared with 5,444 objects tagged with maxspeed=signals. - There is editor support: JOSM's "maxspeed" plugin displays a dashed line on ways tagged with maxspeed:variable=* (though JOSM itself does not have a preset for maxspeed:variable=*) - The ITO "Speed limits fixup" map [http://www.itoworld.com/map/125] recommends using maxspeed:variable=* over maxspeed=signals, despite the former still lingering in the RFC stage. Given the above, I would like to take the initiative and open the voting process for this proposal. Should voting fail, I am prepared to manage a second round of RFC. --K _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
