Bicycle Master Plan

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

• 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.

• 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.

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

Ravensworth Rd

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

Ravensworth Rd - Proposal
10
• Narrow existing lanes to include 1 travel lane and 1
bike lane in each direction
Existing Proposed

Ravensworth Rd
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

Ravensworth Rd
12
• Propose a road diet: one travel lane, one center turn
lane, bike lanes
• Keep parking where it exists today
Existing Proposed

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
13

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 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.

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.

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.

• Does the road feel safer?
• Do you cycle more often on Lawyers?
• Do your auto trips take more time?
• Have auto speeds dropped?

seconds of delay
• Level of Service PM: before 16.9 seconds of delay, after 18.5
seconds of delay
