Often a four lane, undivided road suffers from inefficiency and safety problems. One potential way to improve these conditions plus make it more attractive for pedestrians and bicycles is through a “road diet.” A road diet converts a four lane road into a 2 lane road with a center turning lane. With enough width, a bicycle lane can be striped on the outside edge. The center turning lane allows for left turns to leave the through stream. Ideally, a daily volume up to 18,000 vehicles makes an ideal candidate but volumes as high as 20,000 to 25,000 vehicles could be considered.
