VDOT Annual Repaving•VDOT Summer repaving includes several roads in the Hunter Mill District. Opportunity to review pavement markings and street design. Proposals are limited to restriping the existing pavement.
•Opportunity to slow speeding traffic, provide transportation options, and improve traffic, bicycle, and pedestrian safety
•No additional cost for the County
•Want to hear from the community about issues/concerns• Some concerns may be addressed through restriping
For information on all paving in Hunter Mill District visit:www.virginiaroads.org

County of Fairfax, Virginia
Bicycle Facility Types Sharrow-Shared Lane Markings (SLMs), or “sharrows,” are road markings used to indicate a shared lane environment for bicycles and automobiles. Among other benefits shared lane markings reinforce the legitimacy of bicycle traffic on the street, recommend proper bicyclist positioning, and may be configured to offer directional and wayfinding guidance
County of Fairfax, Virginia
Bicycle Facility Types Bike Lane-Bike lanes designate an exclusive space for bicyclists through the use of pavement markings and signage. The bike lane is located adjacent to motor vehicle travel lanes and flows in the same direction as motor vehicle traffic.
County of Fairfax, Virginia
Bicycle Facility Types Climbing Lane-A climbing lane incorporates two different facilities on the same roadway segment; a bike lane is provided in the uphill direction to accommodate slower moving bicyclists and a sharrow is provided in the downhill direction, where bicyclists can typically travel at a speed closer to motorists.
County of Fairfax, Virginia
Lane Diets
DEPARTMENT OF TRANSPORTATION 19
A Lane Diet is generally described as narrowing travel lanes from a roadway and utilizing the space for other uses and travel modes. Does not involve reducing the number of travel lanes Benefits
◦ Providing transportation alternatives and options◦ Increasing safety for non-motorized users◦ Reduce speeding
County of Fairfax, VirginiaLane Width and Vehicle Speeds
DEPARTMENT OF TRANSPORTATION 20
County of Fairfax, Virginia
Road Diet• 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
• Have now implemented road diets in several places in Fairfax County◦ Lawyers Rd, Soapstone Dr, Kingstowne Village
Parkway, Westbranch Dr, Greensboro Dr, Park Run Dr, Beacon Hill Road, Ravensworth Rd
DEPARTMENT OF TRANSPORTATION 21
County of Fairfax, Virginia
Road Diet Advantages•Improved safety and mobility for people driving,
walking, and bicycling◦ Drivers: Reduction in top end speeding, 15mph>, provides dedicated turn
lane at intersection=reduction in rear end crashes=safer streets◦ Pedestrians: Shorter distances to cross the street, less speeding, more buffer
space from moving vehicles=safer streets◦ Bicyclists: Provides dedicated space to ride, not blocking flow of vehicle
traffic, reduced conflicts and potential for crashes=safer streets
• 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.
