Road Diets• Removing travel lanes from a roadway and reallocating
the space for other uses
• Rule of thumb: Roads with less than 20,000 vehicles per day don’t need four travel lanes
• Kingstowne Village Parkway: 5,300 vehicles per day

EXISTING PROPOSED
Road Diet Advantages
• Improved safety and mobility for cyclists and pedestrians
• Reduction in fastest speeds
• 20% to 50% crash reduction
In existing conditions, if a driver moves slightly over the double yellow line thereis a risk for a head-on crash. In the proposed design, center turn lanes provide a buffer from oncoming traffic.
Existing Proposed
Existing Proposed
In existing conditions, if a driver swerves slightly to the right, there is a risk for a collision with the curb. In the proposed design, bikes lanes provide buffer from curb, although the bike lane shouldn’t be regularly used by drivers.
Existing Proposed
In existing conditions, if a driver pulls over with disabled vehicle, there is a riskof being in a rear-end collision. In the proposed design, bike lane can provide safe area during emergency conditions, and help to avoid a rear-end collision.
Existing Proposed
In existing conditions, if a driver is waiting for traffic to clear to make a left turn, there is a risk of a rear-end collision. In the proposed design, left turn lanes provide dedicated space to make turn, out of the way of through traffic.
Existing Proposed
In existing conditions, if two drivers are making left turns, they block each otherssight distance and view of oncoming traffic. In the proposed design, turn lanes provide better sight lines and view of oncoming traffic.
Existing
In existing conditions, the sight lines for drivers exiting side streets can make itdifficult to see oncoming traffic. In the proposed design, the through lane is awayfrom the curb, and a driver has a better view of oncoming vehicles.
