Sending up this "signal flare" because I want to nominate this article for deletion and I don't know how. Can someone leave instructions (or a trail of bread crumbs to where those instructions are)? Mucho appreciado. +ILike2BeAnonymous 00:02, 22 March 2007 (UTC)Reply

Sinuosity

edit

Out of curiosity, I just used Google Maps to compute the sinuosity of Snake Alley, a one-block section of N. 6th St. in Burlington, Iowa. I was surprised to get a sinuosity of 1.61 (measuring from the center point of each end of the brick-paved "snake". I would have obtained a smaller value had I measured from the center-points of the intersections at each end. I don't know the end points used in the Travel Channel's value for San Francisco's Vermont Street of 1.56 cited in the article, so this may not be comparable, but it makes it clear, Snake Alley holds its own as a very crooked street. This result shouldn't go in the article because it counts as original research, but those interested in numerical comparison of crooked streets ought to dig deeper into this. Douglas W.

I may argue the correctness of using sinuosity as the definition of “crookedness.” A street that begins at one point, goes 1/4 mile to the left, then 1/4 back to the right, has an arclength of 2,640 feet. But this street may actually only progress 100’ between endpoints, giving a sinuosity of 26.4. This would make a street with one turn the crookedest in the world by the sinuosity definition. I believe it would be better to define crookedness by curve-density. Take the total number of radians subtended and divide that by the arclength. That’s how curly the street is.
