A collaboration between city planner, urban designer, and author Jeff Speck (jeffspeck.com), and 3D artist Spencer Boomhower (cupolamedia.com), this series of videos describes some of the most common and most effective road-diet redesigns.
"In the classic American road diet, a standard 4-lane street is replaced by a 3-lane street with a center lane reserved for left-hand turns, yielding ten or more feet that can be used for bike lanes, parking, or sidewalk extensions. While these conversions reduce injuries dramatically, a study of 17 different north American road diets showed zero net decrease in vehicle capacity."
