[mkgmap-dev] Parallel major roads to cyclewaysFrom Gerd Petermann GPetermann_muenchen at hotmail.com on Thu Mar 16 10:06:22 GMT 2017
Hi, I just want to share an idea which might be interesting for cycling maps: In Germany and probably also Austria) many major roads have a parallel cycleway close to it, often only separated by a patch of grass or natural=tree_row. Example: A way with bicycle=designated : http://www.openstreetmap.org/way/243499929 runs next to highway=primary B213 http://www.openstreetmap.org/way/328470949 I think nearly no cyclist likes to use those ways -- they are just a bit safer but still lots of cars are running with 100 km/h next to you -- so I think it would be good to have a way to separate them from other ways where no major road is close. A possible way would be this: Simiar to the new ResidentialHook which sets the mkgmap:residential tag we might implement a hook which collects major roads and calculates an area around it (maybe 20m on both sides). Each way (maybe only those with highway=* ) could be checked against those areas in a way that a rule could decide to "dislike" a way which is mostly within such an area when the map is for cyclists. I guess bridges and tunnels (or more generally the layer tag) needs special handling here. Questions: 1) Do you think this would good to have? 2) If yes, what kind of information would be needed in the style? Gerd
