Agreed. IMO, what downgrades a motorway to a trunk is the presence of anything that stops traffic on the main roadway for intersecting traffic (signals, stop signs, or yield signs). Really, anything more than just a very occasional road intersection that does not occur via ramps, or driveway, should be grounds to call it a trunk (or even lower). In the example, I'd call US41 trunk from Monroe St down to Waldron Dr, and motorway above and below that (at least for the area I looked at), simply based on the appearance of ramp-style intersections vs. traffic-signal-controlled perpendicular intersections. I'm guessing that speed limits would give further justification. -- Alan Mintz <[email protected]> _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
