See http://wiki.osm.org/wiki/DE:Key:hazard And see also https://twitter.com/sfkeller/status/574213951644368896 tl;dr: As a lot of others already said: a quite subjective thing to map. In Germany a lot of more experienced bicyclists regard all separate cycleways or even footways with bicycle=yes as hazard – with good reason. Every year a signifikant number of bicyclists get right-hooked by cars turning right and their drivers not paying enough attention. Every year, a signifikant number of those right-hooked bicyclists die. Never mind the cars parking on the cycleways, crossing service streets, the pedestrians, dogs etc which would make the experienced bicyclist cringe from awe while the less experienced are happy to cruise along with walking speed even on sidewalks where they are not allowed except being ten or younger. Ridiculous is the mentioning of snow or shattered glass. During winter and below 0°C common sense should tell a bicyclist that surfaces might be covered with snow or ice and thus slippery. Some tags regarding winter servicing do exist although the proposal wasn't guided to a voting process. For glass and other stuff on highways: everybody should expect that on the surface of the road stuff may lay which can harm the vehicle – from glass of bottles thrown away by stupid people to shattered windows of a car after an accident to nails and screws falling off carpenter's car to vehicle parts lost while driving (exhaust, bump guard, suspension parts, oil etc). Bicyclists may take into consideration that on a road frequently traveled by cars the smaller stuff like glass gets cleared away by the crumbling effect of the car's tires so that cleaning is in opposition to a cycleway needed less often. (Of course the bicyclist shouldn't ride to the utmost right of a highway were no cars go and all the rubble collects) Thomas ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Even when they are, deducing the visibility algorythmically is hard. You might not want to render hazard=curve, but still want to provide it to drive-assist software. As for drivers being aware of their suroundings, if the local authority decided to signpost a curvy road, it's a good hint that osm should as well. It's not much different from tagging maxspeed. ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Mapping dangerous bicycle locations?
I've brought this up before, but have since gone with the general consensus that this is just too subjective, even if we were to come up with some kind of rubric to standardize things. A big and highly inconsistent issue between regions is regional attitude. I don't care for on-street riding, even in a reasonably extensive network of bike lanes in Portland largely because motorists have a tendency of ignoring lane access completely, often driving against traffic or in reserved lanes to save time with pretty flagrant disregard for safety. Or they just like to intentionally aim for cyclists and pedestrians for laughs. And the cycleways tend to be a congested and unpredictable clog of pedestrians, bicycles, and dogs either off leash or walking on the other side of the roadway from the person holding a 20-foot-long leash, clotheslining everything in their reach. It's an NP-complete perfect storm of pitfalls. Meanwhile, less experienced cyclists would feel safer or safe in any of those situations. Meanwhile, there's very few streets in Tulsa, Dallas or Oklahoma City I don't feel too out of place on and cycleways generally have pedestrian facilities except in suburbs (mostly because the suburbs don't have the traffic to warrant them yet and passing is a nonissue save for the occasional rare blind curve, junction or hillcrest). Roads like Bixby's Memorial Drive (US 64) or Oklahoma City's Portland Avenue (OK 74), with their lack of shoulders, relatively high traffic volumes, and total lack of even a share the road sign might not pose substantial additional risk over a cycleway, mostly because the drivers are mellow. However, the average American would look at that and say, Nope!

Re: [OSM-talk] Mapping dangerous bicycle locations?
The suggests values of weather related - rain/snow will change with the weather .. naturally. slippery = surface related ... could be tagged with surface=? glass-shard .. can be cleaned up, thus temporary like the weather ... I have stopped and swept things off the path .. used some cardboard out of a local bin. I've seen other cyclist do the same. Crime .. effects not only cyclist. As Paul says below - subjective. Not that that is a bad thing .. but makes one mapper tag something as dangerous while another says it is very good. So hard to set hard values on this.
