Avoid Swoops, Slip Lanes, and Sight Triangles

Gentle curves and wide-open corners undermine safety
  • Jeff Speck


HERE’S AN INTERESTING TEST: try to think of a successful downtown with gently curving streets. Drawing a blank? That’s because walkable urbanism is characterized by straight-line geometries, with the occasional circle or oval thrown in, but no swooping curves. Medieval urbanism is cranky, not curvy, and even Frederick Law Olmsted, the king of curves, got straight as an arrow when he arrived downtown.
