Hi!

Just wanted to let you know that in Latvia there is general consensus to tag ways with blue cycleway traffic signs as cycleways, rather than footways. So these sidewalks should ideally be converted to `highway=cycleway` + `foot=designated` + (+ `bicycle=designated`) `segregated=no` (or the JOSM variant, although most stuff in Latvia uses iD variant). There are certain legal traffic law distinctions between sidewalks and shared cycleways, so it's best to be exact.

I can't say for other countries without looking into it, but on OSM in general European blue cycleway signs are tagged as cycle infrastructure.

Thanks
