Hi, Am new to OSM and am looking for inputs on if I can get information on roads with SharpCurves. I have seen a couple of links (posted below) where users pointed out proposed features for curves like Warning: CurveLeft or Hazard: Curve. But I dont think there is supports for the same. So some one please clarify if I can get information about curves. Thanks in advance. https://wiki.openstreetmap.org/wiki/Proposed_features/Extended_traffic_signs_tagging https://wiki.openstreetmap.org/wiki/Proposed_features/hazard Vamsi asked 29 Jan '18, 18:09  vamsimp edited 30 Jan '18, 21:38  aseerel4c26 ♦ |
One Answer:
However aseerel4c26 has a valid point. Sharp curves can be calculated very easily by navigation software if the roads are mapped with sufficient detail. Of course there can be additional conditions making a curve particularly difficult, such as a bad surface or frequent wetness due to high humidity, a stream running over the road and similar causes. In these cases just looking at the road geometry isn't enough. See also answered 31 Jan '18, 14:14  scai ♦ |
what do you mean by "get information on roads with SharpCurves"? Do you want to contribute to OSM or do you want to use OSM's data? Please describe a bit.
I assume varsimp wants to find tight radius, high G curves and although they could be estimated a bit from Bing or DG the camber and road surface friction can't be.
I basically want to use OSM data to find if there are curves on the roads.
@Andy, Thanks for the info
Okay, so are you asking for tags which are possibly used to mark such curves? What about calculating a curve radius based on the geometry or curves?
