  2. 2. County of Fairfax, Virginia Department of Transportation 2 Overview • Why are we here? • What are we asking today? • What projects are being proposed? • Where are we in the process? • What are the next steps?
  3. 3. County of Fairfax, Virginia Why are we here? • VDOT 2015 Summer repaving includes many streets in Tysons • Opportunity to improve vehicular safety, improve traffic flow, improve pedestrian safety, and add bicycle facilities. Implement the idea of a more walkable/bikeable Tysons today! • Interim solution until development occurs and streets constructed as the ultimate sections described in the comprehensive plan • Low to no cost for the County Department of Transportation 3

  11. 11. County of Fairfax, Virginia Road Diet Advantages • Improved safety and mobility for cyclists and pedestrians • Reduction in fastest speeds • 20% to 50% crash reduction
  12. 12. County of Fairfax, Virginia In existing conditions, if a driver moves slightly over the double yellow line there is a risk for a head-on crash. In the proposed design, center turn lanes provide a buffer from oncoming traffic. Existing Proposed
  13. 13. County of Fairfax, Virginia 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.
  14. 14. County of Fairfax, Virginia Existing Proposed In existing conditions, if a driver pulls over with disabled vehicle, there is a risk of 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.
  15. 15. County of Fairfax, Virginia 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.
  16. 16. County of Fairfax, Virginia Existing Proposed In existing conditions, if two drivers are making left turns, they block each others sight distance and view of oncoming traffic. In the proposed design, turn lanes provide better sight lines and view of oncoming traffic.
  17. 17. County of Fairfax, Virginia Existing In existing conditions, the sight lines for drivers exiting side streets can make it difficult to see oncoming traffic. In the proposed design, the through lane is away from the curb, and a driver has a better view of oncoming vehicles.
