Hi brainwad,

These are "Farbliche Gestaltung der Strassenoberfläche" and they have absolutely nothing to do with cycling. They are meant to make the street look narrower to incentivise reducing speed (it's a 30 kph street).

See this spot on bikeable: https://www.bikeable.ch/spots/4822

IMO it's wrong to tag this as a shared lane, every Swiss street is allowed for bicycles by default anyway, and I avoid this street as there is simply no space for cycling in traffic. Tagging it as such would make it look "cycle friendly", which it's definitely not.

The same goes for Kalkbreitestrasse in your other changeset.

And: what is cycleway=shared_bike?

Happy Mapping
