Sorry, but you are wrong if you are talking of "my idea" . I don't view any
future to a unique key for every traffic sign (would be interesting for
every group as a concatenation of pairs as: traffic_sign=warning
warning=bump), I see varied values. So as you can see with the example of
the proposal [1] , the result will not be stop:x = yes instead of

highway=stop >> kind of traffic sign in a unified scheme
traffic_sign:forward=ES:R2 >> Spanish code of the traffic sign (wil be good
for rendering the exact image)
side=right > side of the road it is.

I think a scheme with the various values is more complete than create a key
for every traffic sign because then every traffic sign will fit in every
country with the same key, as you can see in Taginfo [2].

only problem will be if you connect other way to that node, if you split a
way but you have the same direction in the two segments of a way I don't
think there will be any problem with that.Also you can split the way next
pixel of the pixel of the traffic sign.
