Re: [Tagging] Sidewalks vs Footways
Hi. I'm from Germany, and therefore not argumenting with the English language, but footway is a more general term as distinct ways for people moving by foot are footways, too. Ways along or part of a street with main purpose of often motorized vehicles - a indication for that is, that cars are located in the middle and therefore with less crossings than pedestrians - should be distinguished from standalone footways. Therefore I would prefer sidewalk or pavement. Of these, sidewalk for me is more self explaining than pavement. I'm good enough speaking English to know even the word pavement - but that the way, where you walk along a street on one side is called sidewalk is better to understand even if the vocabulary is not known in particular.

Re: [Tagging] Sidewalks vs Footways
Based on this thread, there seems to be general consensus that the term sidewalk is less linguistically ambiguous than footway. Where folks are concerned about dual meaning, we can ensure that's resolved via fixing the wiki, checking JOSM presets, and checking Potlatch/PL2. Data consumers who are using either tag should be aware that neither has been accepted, so they're using it at their own risk.

Josh, There's nothing wrong, pe se, with that. I've gone back and forth on whether that's the right way to go or not, and I think it's up to individual mappers, but after considering it, I've decided I prefer the road to be tagged for the following reasons: 1) It's less ways overall. That's not normally a consideration I'd consider important, but in this case, I'd say that the sidewalk is a feature of the road, and therefore makes the map more useful. 2) Sidewalks are sometimes interrupted, but still logically connected. An example of this would be a crosswalk. The sidewalk ends, but roads continues, and the governance of whether a pedestrian can cross can be placed at the intersection. 3) Making sidewalks a road feature aids the router. It lets the router say things like Walk along Main Street. If the term sidewalk is used for this proposal would it make sense to also apply it to individual ways? Individual ways which are unassociated with a road are footways/paths, and not sidewalks. - Serge ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Sidewalks vs Footways
You also have the fact that it may be physically possible to cross from a sidewalk on one side of the street to the other, due to a lack of barriers, and yet be inadvisable to do so at certain points (in the middle of a blind curve, for instance, or on a road that has heavy traffic and lacks pedestrian crossing-signals). In some cases, crossing may be possible at some times of day but not others. Hopefully, there would be a way to tag this information for use by routers. ---Original Email--- Subject :Re: [Tagging] Sidewalks vs Footways From :mailto:dieterdre...@gmail.com Date :Thu Mar 17 14:48:22 America/Chicago 2011 The point of having a separate way is to indicate that it is not possible to cross from one to the other (if you see the sidewalk like a lane), if you take the kerb as an barrier, mapping them separate might have a certain sense (although a kerb is not a serious obstacle for the biggest user group of the sidewalk:t pedestrians). I wrote a proposal for the area-relation which tries to combine 2 aspects: the area aspect of a road, and the possibility to change from one way to another without connecting node (the router would also consider intersections of another lane/highway as valid). We would draw the outer limits of the footway and interpolate the area from there to the center or to the other side of the road. There would not be mapped connections from this way to the centerline or to the other side, but routers could understand that you can cross. For the barriers there is also tags to map them (be it a wall, grass, a kerb, or whatever).
