  • 9. 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
  • 10. 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.
  • 11. 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.
  • 12. 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.
  • 13. 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.
  • 14. 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.
