<div dir="ltr">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.<div><br></div><div><a href="https://wiki.openstreetmap.org/wiki/WikiProject_Thailand#Bicycling_tagging_.28currently_for_Chiang_Mai_only.29">https://wiki.openstreetmap.org/wiki/WikiProject_Thailand#Bicycling_tagging_.28currently_for_Chiang_Mai_only.29</a><br></div><div><br></div><div>Dave</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 16, 2017 at 5:06 PM, Gerd Petermann <span dir="ltr"><<a href="mailto:GPetermann_muenchen@hotmail.com" target="_blank">GPetermann_muenchen@hotmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I just want to share an idea which might be interesting for cycling maps:<br>
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.<br>
Example: A way with bicycle=designated :<br>
<a href="http://www.openstreetmap.org/way/243499929" rel="noreferrer" target="_blank">http://www.openstreetmap.org/<wbr>way/243499929</a><br>
runs next to highway=primary B213<br>
<a href="http://www.openstreetmap.org/way/328470949" rel="noreferrer" target="_blank">http://www.openstreetmap.org/<wbr>way/328470949</a><br>
<br>
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 --<br>
so I think it would be good to have a way to separate them from other ways where no major road is close.<br>
<br>
A possible way would be this:<br>
Simiar to the new ResidentialHook which sets the mkgmap:residential tag we might implement a<br>
hook which collects major roads and calculates an area around it (maybe 20m on both sides).<br>
Each way (maybe only those with highway=* ) could be checked against those areas in a way that a rule could<br>
decide to "dislike" a way which is mostly within such an area when the map is for cyclists.<br>
I guess bridges and tunnels (or more generally the layer tag) needs special handling here.<br>
<br>
Questions:<br>
1) Do you think this would good to have?<br>
2) If yes, what kind of information would be needed in the style?<br>
