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. Bike lanes are typically on the right side of the street, between the adjacent travel lane and curb, road edge, or parking lane.
County of Fairfax, Virginia
Bicycle Facility Types• Buffered Bike Lane-Buffered bike lanes are conventional bicycle
lanes paired with a designated buffer space separating the bicycle lane from the adjacent motor vehicle travel lane and/or parking lane.
County of Fairfax, Virginia
Ravensworth Rd• From Braddock Rd to Little River Turnpike• Bicycle Master Plan calls for bike lanes• 2 main Sections based on roadway width
• Braddock Rd to Rawlins Dr: 32’, 2 lanes, No Parking• Rawlins Dr to Little River Turnpike, 48’+, 4 lanes, Some Parking
• Combination of lane diets and road diets, keep parking where it exists today

This is the typical roadway section from Braddock Rd to Rawlins Rd: 2 lanes, 32’.

Ravensworth Rd - Proposal
Department of Transportation 10
• Narrow existing lanes to include 1 travel lane and 1 bike lane in each direction
Existing Proposed
County of Fairfax, Virginia
Ravensworth Rd
Department of Transportation 11
• This is the typical roadway section from Rawlins Rd to Little River Tpke-4 lanes, 50-60’.• Propose a road diet: one travel lane, one center turn lane, bike lanes, and parking
County of Fairfax, Virginia
Ravensworth Rd
Department of Transportation 12
• Propose a road diet: one travel lane, one center turn lane, bike lanes
• Keep parking where it exists todayExisting Proposed
County of Fairfax, Virginia
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
• Have now implemented road diets in several places in the county• Soapstone Dr, Lawyers Rd, Kingstowne Village Parkway, Westbranch Dr,
Greensboro Dr, Park Run Dr, Beacon Hill Road
Department of Transportation 13
County of Fairfax, Virginia
Road Diet Advantages• Improved safety and mobility for cyclists and pedestrians
• 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
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.
County of Fairfax, Virginia
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.
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.
County of Fairfax, Virginia
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.
County of Fairfax, Virginia
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.

lanes would be added by narrowing lanes• Proposal would eliminate short section of 1 lane in each direction
to keep connectivity of bike lanes• Between Rectory Lane and Commons Drive-Northbound (0.1 mi)• Between Patriot Drive and Rectory Lane-Southbound (0.2 mi)
