for this reason the solution of tag the traffic signs ON the way it's the
best way to do it. Traffic signs are relative to their ways (because if the
way does not exist the existance of traffic sign is non-sense). Ways have
direction, also their nodes can have this reference.

Relations are complex and also are an item not all the mappers can do. Why
don't accept the easiest way to get this information?
(Now it works without relations)
