Rationale
Provide a way to indicate an incline along any route, not only a highway. Also allow a route with an incline to still be a highway.
Applies to
- Ways
Usage
Incline is given in the direction of the segment/way, with a 10% grade indicating a change of 1 vertical unit for every horizontal unit travelled. Incline can be positive or negative.
Tags
A road with a 10% grade up could be tagged as follows:
<tag k="highway" v="unclassified"/> <tag k="incline" v="10%" />
Deprecates
highway=incline highway=incline_steep
Rendering
Misc
If this is accepted, the highway values "incline" and "incline_steep" should be deprecated.
Comments
I don't think, this is the same as highway=incline or incline_steep, as it is designated to use with nodes! So the deprecation is not appropriate here. The highway=incline tag with node just symbolizes an incline sign to be rendered above some node - nothing more. If you need exact number, this can be solution, but I don't think, this adds some more valuable information. IMO the incline of 5%-15% is the same as 15%-30%, because the cars always go slow or slower and therefore the tag/value incline and incline_steep is ok for me. --Kubajz 07:49, 25 July 2007 (BST)
- well, specifying the slope / downslope grade is important for a lot of areas. see for instance the polish bus that crashed a few days ago (Sxpert 09:49, 25 July 2007 (BST))
- So far as I can see this adds information that someone might find useful and there's no harm in having it! The precise incline is very handy for people in rubbish old cars, for cyclists and no doubt other users I haven't thought of TomChance 11:49, 25 July 2007 (BST)
- Nice for cyclist and people towing caravan (Gummibärli 12:23, 29 July 2007 (CEST))
OK, if we approve this, we should consider rendering. My opinion is to add this information to nodes and not to segments or ways. The reason is following: Where should be the mark rendered? In the middle, on outer limits, equidistantly along the way? If we use a node, the location is exact. Other thing to consider is the value. Is it the value a maximum steep or average? How to determine the value? In our country other mechanism is used to determine the value. 10% is 1 unit vertically to 10 units horizontally and not 1:1 (as this is 45˚ and therefore very very steep incline). I would approve this proposal, but there are things to think about before we approve this. --Kubajz 12:12, 7 August 2007 (BST)
- From my limited experience of incline signs in the UK it would make more sense to cut a way into smaller ways and have one with the incline data, rather like we do for bridges. It's usually a section going up a hill. I can't imagine using this tag for every incline in south London, only where there's a signpost warning of a particularly steep incline! As for rendering, a little graphic of a slope with a figure in degrees on or next to it would be good. TomChance 13:58, 7 August 2007 (BST)
Couldn't this be computed from the elevation data (tag ele)?
- yes, or from SRTM contour data which is currently being experimented with (see talk mailing list)Myfanwy 21:44, 9 January 2008 (UTC)
- Will that SRTM data really be good enough to discard this tag (like climbs going up 40m at 15%)? By the way, does the incline tag show average of maximum incline? --Eimai 21:06, 14 February 2008 (UTC)
(Added after vote:) No - apart from very large hills. The SRTM data is both incomplete - it is only up to around 60N and 55S, and low resolution - 90m. Of the 10 incline signs I can think of round here (Fife, Scotland), maybe one of these might be detected as steep by the SRTM data. The SRTM data is also noisy.
I think this tag is important for wheelchair users. About 6% is the limit they can usually handle (German recommendation for ramps for the handicapped). --Lulu-Ann 12:25, 26 May 2008 (UTC)
Why does tag:highway=incline redirect to an alternate proposal that was rejected? Could someone make a page on the proper use of tag:highway=incline as it applies to nodes, mentioned on the Map Features article? Also, I think the definition of 10% equals one vertical unit per horizontal unit is a typo. Should be "1% is one vertical unit per 100 horizontal units". But I didn't change it here because I don't know to what extent inclines have already been tagged with this flawed definition. Vid the Kid 16:19, 24 December 2008 (UTC)

I disapprove this proposal, it will be rendered obsolete by SRTM contour data-- Myfanwy 21:43, 9 January 2008 (UTC)
- Actually this tag is really useful when you need to tag a steep hill in a city, such as Edinburgh, where the difference in height won't be picked up by the STRM data which is not detailed enough. Smsm1 22:02, 22 July 2008 (UTC)
