To me, having two different tags (footway, pedestrian) to represent the same type of object is confusing, as is using the same tag (footway) to represent two different types of object. Mmh, I tend to differ between an area signed as pedestrian and a square without any sign or signs for foot, bicycle and other modes. I also met highway=path + area=yes. In general highway=pedestrian is often interpreted wrong, especially if lots of special access condition are tag. At least for bicycle this is less problematic if we are using path or footway. Why do we use highway=pedestrians at all instead of footway or path as long as it is not explicitly signed ?

Re: [Tagging] bridge=humpback ?
No need to define it as UK-only... such bridges occur across the whole world, I am sure. The UK may be unique by having a specific road sign, which may indicate that a bridge could/should be tagged as a humpback (as stated in the wiki[1]). There is also a sign for explicitly indicating a risk of grounding often seen at railway crossings. In the UK it can be made objective by linking the use of the tag to the presence of the sign, but then we would miss the many bridges which the average person would call a hump bridge but are not signed as such. I would suggest something like a bridge requiring driving speed to be reduced due to the vertical profile (i.e. not because it is narrow, or some other attribute). Not sure this depends on who is driving by the way, the laws of dynamics apply to all of us equally. But I agree that calculating whether a particular truck can pass a particular bridge is not easy to put into simple tags.

Regardless of whether it's mapped as a footway or as a pedestrian area it looks like a fairly extreme case of mapping for the renderer with no thought given to map usability. If you look in the area of this node: http://www.openstreetmap.org/node/2622468074 The data as it exists now suggests that there's no access west from this footway island to the pedestrian crossing across Millbank, or actually anywhere on the west bank of the Thames. This pedestrian island functionally duplicates the real footway http://www.openstreetmap.org/way/256600109 (from which you can get north and south, though not west) I'd be in favour of a similar linear / area split as there is with rivers = waterway=river - is the line of the river for e.g. routing purposes; waterway=riverbankthe outline of the bank which can be used for rendering but ignored for routing.

Re: [Tagging] bridge=humpback ?
Is there a tag for a non-intended, not speed-enforcing hump on a road? This can occurs on a railway crossing, or due to the roots of a vigorous tree.

Re: [Tagging] bridge=humpback ?
Exactly my point. In the UK you can be objective by linking it to the presence of the sign, other countries may not use a sign. Having established that such information (this bridge requires you to slow down to avoid being launched) may be useful in certain cases, now we are trying to represent that information in OSM. The reasonable_max_speed would be a start, but if it is accompanied by some indication of WHY the speed is what it is, like reasonable_max_speed:reason=hump_bridge, then everybody could be happy. OSM is essentially a 2D system. Whereas hazards like sharp bends can possibly be derived from 2D information, anything significant in the vertical plane needs all the help it can get, including hump bridges and steep inclines. I'm not sure where you are from Richard, but don't you agree a bridge like this is asking for some special tag? http://farm2.static.flickr.com/1263/1186115057_7f88a4aaed_o.jpg Same applies as far as I'm concerned for dips and steep hills which constitute a hazard. As they can't be derived from 2D geometry, let's find a way of marking them explicitly. There has already been work done on incline=*: http://wiki.openstreetmap.org/wiki/Incline --colin On 2014-08-10 23:28, Richard Z. wrote: On Sun, Aug 10, 2014 at 06:14:24PM +0200, Colin Smale wrote: It is neither constructed with the intention of calming traffic, nor is it intended as any kind of barrier (a bridge is usually exactly the opposite!)

Re: [Tagging] Using highway=footway as an area

(checking the history previously they were both highway=pedestrian. Regardless of whether it's mapped as a footway or as a pedestrian area it looks like a fairly extreme case of mapping for the renderer with no thought given to map usability. There could be a Bridge polygon for instance to unify the ways on the bridge Cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
