If the point of interest is related to travelling along the road, it 
makes sense for the nodes along the road to have suitable tags.

You could have one that says "traffic lights", one that says "pedestrian 
crossing", and so on, which means that any driving directions can say 
things like

"Take the first left after the pedestrian crossing".
