2017 VDOT Repaving
•Annual VDOT maintenance program to repave and
restripe streets
•Repaving creates opportunity to make
improvements-LIMITED TO STRIPING CHANGES
•Based on bicycle master plan, community
concerns, feedback, and input
•Many streets in Hunter Mill planned for repaving,
only a few for bicycle facilities

Less dedicated space and comfort

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

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.

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.

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.

Restriping Opportunities
•Opportunity to improve roadway safety
◦Narrow Travel Lanes: Lane Diets
◦Reduce the number of travel lanes: Road Diets
◦Add dedicated space for bicyclists
◦Add crosswalks

Lane Diets
15
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

2015 Lane Diet Project-Annandale
Road
•Pre-Project Conditions
•Two travel lanes 16’+ wide
•Two parking lanes 8’ wide
•Post-Project Conditions
•Two travel lanes 11’ wide
•Two bike lanes 5’ wide
•Two parking lanes 8’ wide

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
◦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 there
is 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 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.

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.

2015 Road Diet Greensboro Drive
•Pre-Project Conditions
•Four travel lanes, 12’ wide
•Post-Project Conditions
•Two travel lanes 12’ wide
•One center turn lane 12’ wide
•Two bike lanes 6’ wide

Community Feedback
•Street Design Standards
•Travel Lanes 10’-11’, does not include gutter
pan
•Parking Lanes 7’-8’, includes gutter pan
•Bike Lanes-5’-6’ if next to parking lane
•4’ minimum if adjacent to gutter pan
•Buffer space-2’ minimum between travel
lanes or parking lane and bike lanes
29

Next Steps
•Comment period open for three weeks
• December 2, 2016
•FCDOT and VDOT will review input and create
proposals for each street under review
•Public Meeting in January/February 2017 to gather
feedback on proposed designs
•Finalize design plans spring 2017 and repaving occurs
in summer/fall 2017
