Road Diets

Road Diet Basic Design

According to the Virginia Department of Transportation (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%, 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.

Bike Lanes and Right Turns

Bike lanes are to separate bikes, e-bikes, motorized skateboards and scooters from other traffic. Bike lanes may be marked by signs, as well as white lines or colored pavement, and symbols applied to the pavement. Parking is not allowed in bike lanes. Often cyclists need to ride outside a bike lane when it is too narrow or hazards are present.

Motorists will not drive in a bike lane except in some cases when making a right turn. Motorists are only allowed to cross into a bike lane when turning right. Before crossing a bike lane to turn, drivers must scan for cyclists to the right, rear and forward, use their turn signal, scan again and then merge into the bike lane for the turn.
