Yes. That is the intent. I've been adding speed limits to the map on various roads around here. The notes are serving as a temporary aid in that effort. 

I've left these speed limit notes in place for the moment while I researched if adding the signs to the map was appropriate. From what I can tell it is not. It seems the conventional way is to just add the maxspeed and source:maxspeed=sign tags to the way segments as required. 

When the notes have finished serving their purpose, I intend to mark the notes resolved. In fact, there are several notes that I've made in this area that can be marked so now. I will be cleaning those up.
