Overview•Why are we here?•What are we asking from the community?•What projects are being proposed?•Where are we in the process?•What are the next steps?



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

•Twin Branches Road ◦South Lakes Dr to Lawyers Rd = 1 mi

•Colts Neck Rd ◦Reston Parkway to Sunrise Valley Dr = 1.75 mi

•North Shore Drive◦Ring Road to Park Glen Ct = 3.5 mi


November 14th Recap


November 14th Recap•Multiple stations for people to give feedback

• Station 1-Where you live, where you want to be able to walk/bike, issues, concerns, ideas

• Station 2-What are your priorities? Walking, Bicycling, Parking, Driving

• Station 3-Design your own streets• Station 4-Where do you want to see Capital Bikeshare

stations?

Bicycle Facility Types

•Sharrow•Climbing Lane•Bike Lane

More dedicated space and comfort

Less dedicated space and comfort


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


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.


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.


Lane Diets


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



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



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.

•Reston Parkway to Glade Drive• Narrow each travel lane to 11’• 5’ bike lane in each direction• Parking remains everywhere it exists

today

•Glade Dr to Colts Neck Ct• 1 travel lane, 1 bike lane in each direction, and a center

turn lane• Evaluate new crosswalks

•Colts Neck Ct to Sunrise Valley Dr• 1 SB lane, 2 NB travel lanes, 1 bike lane in each direction




•Glade Dr to Steeplechase Dr• Narrow Travel Lanes and add bike lanes

Existing Proposed




•Steeplechase Dr to Glade Dr• Narrow Travel Lanes, keep parking, add bike lanes + sharrows

Existing Proposed




•Reston Parkway to Glade Dr• 1 travel lane, 1 bike lane in each direction, and a center turn

lane• Evaluate new crosswalks

•Road Diet increases crosswalk opportunities by:• Improving sight distance• Shortening crossing distance• Reducing # of travel lanes to cross• Providing refuge space
