It does seem like there is a lot of arbitrary conditions separating some of these road types.  It would be nice to have solid reasoning for tagging a roadway a certain way instead of how "important" it is.

The routing engine should be able to take into account the road surface, number of stop lights, and other factors into consideration if there are multiple routes of similar highways that are "important", IMO.  Any idea why trunk was established in the first place?
