Road Diets

A road diet is a way to change how people move on a roadway to improve safety, better serve all of the people who use it, and improve the surrounding community (Fig. 1).  The U.S. Department of Transportation's Federal Highway Administration promotes road diets because they provide substantial safety and multimodal benefits.  


Figure 1.  A "road diet" can refer to a variety of lane reconfigurations to improve street function and safety.

The City of Little Rock has already done several road diets, including 12th St., Main St., Chester St., Daisy Bates to address the concerns of the communities in those areas.  Are you happy with the safety and service of the streets in your community?  What concerns do you have?  A road diet may be one way to address your concerns.  If you're interested, please watch the videos (Figs. 1 & 2), read "Road Diets and Safety" below, and review the resources below.

Road Diet Topics

“We now know that there is no reason for any urban street in America to have four lanes. It cannot be justified. It took a while to figure it out, but the data are clear. When a four-lane street is converted to a three lane street, in which the center lane is reserved for left turns, the capacity of the street does not drop.” Jeff Speck, Walkable City Rules, 2018
