For Urban "Other freeways and expressways" and Rural "Principal Arterials," I go back to my controlled access rule of thumb. If it is controlled access, I tag as motorway, otherwise, it's tagged as trunk. If I were to go strictly on HFCS, K-10 between Lawrence and Lenexa, US 59 between Lawrence and Ottawa, and US 75 between Topeka and US 56 would all be trunks, even though all of those facilities are clearly 4-lane freeways. FTR, I have not found a fully controlled-access facility classified as "secondary arterial" or lower on any official DOT HFCS map. > On Sun, Jun 30, 2013 at 1:58 AM, Paul Johnson <ba...@ursamundi.org> wrote: > >> Yeah, trunk seems more appropriate to me, motorway seems to make me think >> of a limited access roadway with a statistically insignificant chance of >> getting hit head on. >> > I wouldn't considered a freeway to have a "statistically insignificant" chance of getting hit head-on. Depending on traffic, and the demographics of the drivers, you could wind up having a better change of a median crossover collision than a head on on a super-two. -- Richie Kennedy www.route56.com * richiekenned...@gmail.com facebook.com/route56 * twitter.com/route56 I'm not crazy.
