[mkgmap-dev] Parallel major roads to cycleways

From lig fietser ligfietser at hotmail.com on Fri Mar 17 08:20:11 GMT 2017

Interesting idea Gerd but those roads are also arterial connections to get in or out of the city so for commuting cyclists essential.

A benefit to have such hook is that I can copy the name of the major highway to the parallel cycleway if it lacks a name. This is for address search essential, since the major highway is often not routable in my maps.


Another benefit could be that I can force the router to route on those parallel and often obligatory cycleways and give a high penalty (lesser road_speed or road_class)  for the major highway sections. In OSM those highways often lacks a tag bicycle=no or bicycle=use_sidepath where in reality the parallel cycleways are obligatory.

There is a fledgling effort underway here in Chiang Mai to do a similar thing. This effort centers around the desirability of a route for bicycling. It deals with scenic vs dangerous roads for cycling and the 3 point system it uses might be insufficient for your needs but it might be adapted. Worth a look at any rate.

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
