As you know Mapillary has released a layer with the results of their recognition system of traffic signs to JOSM and iD (I wish OSC will do the same soon) . This means now we have a reliable and open (CC) source to map traffic signs in a easy and complete way inside OSM (instead of the work-in-place,of course ). The thing is: Mapillary is ready...but is OpenStreetMap ready? I think it would be.
How? With an advanced and extended traffic signs tagging scheme like https://wiki.openstreetmap.org/wiki/Proposed_features/Extended_traffic_signs_tagging or similar that enables the community to tag nor only the 9 main kinds (stop, give_way, traffic_signal, maxspeed, minspeed, maxaxleload, maxweight maxlenght maxheight, city_limit) but the others less famous (e.g. in Spain we have more than 300 different traffic signs, with nowadays scheme you can cover...only 10% without using country code). The idea is simple: following the scheme like key=traffic_sign > "subkey"=value (maxspeed would be a good example) we can afford almost the totality of the traffic signs. We can use the classification you have in every countries' traffic law. To clarify also the meaning and the drawing of the traffic sign we can use also the countries traffic sign unique code for every traffic sign. Example: traffic_sign=warning warning=maxheight maxheight=4.4 traffic_sign:forward=NP:B20 side=right to have https://upload.wikimedia.org/wikipedia/commons/thumb/d/d6/Nepal_road_sign_B20.svg/100px-Nepal_road_sign_B20.svg.png The system has to be scalable to be able to expand it for every country in the world, for every traffic sign (now in taginfo you can find more than 10000+ in 40 countries), so I think it will be possible. It would interesting talk also with Mapillary's people (I have contact with traffic sign recognition system team) or OSC People. What do you think?
