Make highway=track and bicycle=designated/yes more visible

[LucasNicola]

In rural areas, there are lots of agricultural tracks (highway=track and tracktype=grade1) that are used a a cycle network (bicycle=designated or yes) as they are safe, comfortable, and already existing.
Unfortunately in cyclosm they are not rendered in blue like others cycleways and cyclepaths unless they are part of a cycleroute, which is not always the case. That makes them invisible to cyclists and it is a shame.
Could it be an improvement for the rendering ?
Thanks for reading me.

Indeed, I think we only do it for highway=path or highway=cycleway (shared cycleways in the cities) but not highway=track.

Would you have some area which can be used for testing and is representative of the lack of render?

Thanks!

Thanks for your reply! I live in Alsace, France and I'm thinking of this area South of Neuf-Brisach : 47.9885,7.5991
For instance there is a track with bicycle=designated going South to North from Nambsheim to Vogelgrun which is not rendered at all on cyclosm.
In Germany there are tons of them but most are part of a network so the render is good.
Let me know if I can help!

To add to this highway=track + bicycle=designated is already documented (on the German wiki):

Should this situation be rendered the same as highway=path + bicycle=designated? Perhaps the rendering for highway=track needs to be redone altogether, as we render access restrictions (e.g. motor_vehicle=no as light green) on other road types but not on highway=track.

Hi, any update? Have you tested some render on an area?
Thanks!

Sorry for my late reply, I've been quite busy lately and although I'm not forgetting this issue, I'm not sure when I will be able to commit enough time to tackle it. Happy to take any PR!

To add to this highway=track + bicycle=designated is already documented (on the German wiki):

From my understanding (I can't speak German, relying on automated translation), this is not a regular highway=track but it requires further access restrictions tags (access=agricultural|destination for example). That being said, I think I would be fine to render a highway=track with limited motor vehicles traffic as a highway=path (and same thing with the subrender with explicit bicycle designation).

A highway=track with limited motor traffic should basically boil down to a highway=path which is large enough to fit a potential motor vehicle.

Referencing #672 which is quite related.
