Road Diet

Road Diet - Basic Design

According to VDOT, a classic Road Diet typically involves converting an existing four-lane, undivided roadway to a three-lane roadway consisting of two through lanes and a center, two-way left-turn lane and bike lanes or paved shoulders.

The resulting benefits of the 4-3 conversion include an average crash reduction of 19 to 47 percent, reduced vehicle speed differential, improved mobility and access by all road users, and integration of the roadway into surrounding land uses that results in an enhanced quality of life.

A key feature of a Road Diet is that it allows reclaimed space to be allocated for other uses, such as turn lanes, bus lanes, pedestrian refuge islands, bike lanes, sidewalks, bus shelters, parking or landscaping.
