Here's a quick and dirty attempt to automatically determine arterial streets without any prior knowledge about the arterial status of a street. The idea is: a shortest path tree is taken for a bunch of random points, and the trunkyness of each branch was determined. The trunkynesses of the roads are summed, and this is the resulting map. It sort of works.
