[mkgmap-dev] Parallel major roads to cycleways

Fri Mar 17 14:48:56 GMT 2017

Hi Jakob,

I am also one of those who create their GPX files with other (online) programs, but I've still not found one which
I can configure so that my route preferences are met, so I hope that I can improve the routing
in Basecamp/Mapsource. I use the routing on device only
for small distances, e.g. when I am searching for a supermarket, restaurant etc. while I follow a GPX track.

Hopefully this does not dampen your enthusiasm. I like the idea, but I think that this is a lot of effort with little application
The first reason is that Garmin devices are just terrible at bike routing, every single cyclist I know just use it for navigating a GPX that came from a online routing service like cycle.travel or BRouter, or routes from other people.
The second reason is that even the bikers who route on the device might like these ways. Separated cycle ways along major roads are not dangerous, just loud, and often paved and in very good condition.

So would it be nice to have the option? Yes
Would many people really use it? I doubt it.

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?
