Because we can't. WA-290 at Starr Road is two paved lanes wide, with 12-foot lanes and 4-foot paved shoulders. It has a speed limit of 45 mph. WA-261 at Lyons Ferry Fish Hatchery is two paved lanes wide, with 11-foot lanes and 4-foot paved shoulders. It has a speed limit of 50 mph. Two very similar-looking roads, so they should have similar classifications, right? WA-261 runs from nowhere much to nowhere much, and sees maybe 300 vehicles a day. In contrast, WA-290 is the other major route between the Spokane and Coeur d'Alene metropolitan areas (the main route is the interstate), and sees 13,000 vehicles a day go by. If you omitted WA-261 from a map, almost nobody would notice. If you omitted WA-290, people would discard your map as useless. I've driven both roads, and they *feel* very different. But it's not a difference that I can put into numbers -- at least, not without putting a traffic counter out for a few days. -- Mark _______________________________________________ Talk-us mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-us
