I've thought of doing it this way too for intersections of two dual 
carriageways. With two intersecting single carriageways I'd put the traffic 
lights in the single intersection node.

The problem I have is, that I don't know of a way to avoid "passing" an extra 
traffic light for intersections of a single and a dual carriageway. Does 
anyone know a solution for that?
