[mkgmap-dev] Parallel major roads to cycleways

From Gerd Petermann GPetermann_muenchen at hotmail.com on Thu Mar 16 10:06:22 GMT 2017


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 :
runs next to highway=primary B213

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.

1) Do you think this would good to have?
2) If yes, what kind of information would be needed in the style?
