Hello can you please point out an example of using a polygon to define an intersection? I haven't seen this technique yet.
I don't have one (although I'm pretty sure that someone already tried somewhere as I know that some places have all roads drawn with polygons). I just wanted to say that "simplifying an intersection to a single node" is not "technicaly more accurate".
As far as accuracy, I was referring to it being a single intersection of roads topologically, governed by a single switching strategy - that a single node (or polygon) is more topologically accurate than 2 or 4 nodes.
