My idea is to use mapillary traffic sign recognition to find places with missing bicycle infrastructure in osm data. The idea was already implemented for different purpose here:
It is simple: highlight places on the map that mapillary found traffic sign connected with bicycle and there is no bicycle data on the map.
In Poland we are experiencing boom in new bicycle infrastructure and alot of it stays not maped for long time. Unfortunately im not a programist and dont know how to do this on my own. Mybe someon could pick up this?
