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


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.


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.


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


Average Daily Traffic Volume: 14,000-15,000

Speed Limit: 35 mph

Connection between neighbor-hoods and the Annandale CBC


Ravensworth Rd


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


Ravensworth Rd - Proposal


• Narrow existing lanes to include 1 travel lane and 1 bike lane in each direction

Existing Proposed


Ravensworth Rd


• 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


• Propose a road diet: one travel lane, one center turn lane, bike lanes

• Keep parking where it exists todayExisting 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



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


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.

Project Impacts


• Ravensworth Rd and John Marr Dr /McWhorter Pl• Level of Service AM: before 12.3 seconds of delay, after 14.2

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

seconds of delay


Heritage Dr• From Ravensworth Rd to Little River Turnpike

• Bicycle Master Plan calls for bike lanes, small section of sharrows

• 2 Sections based on roadway design• Ravensworth Road to Rectory Lane: 2 lane undivided• Rectory Lane to Little River Turnpike: 4 lane divided



Heritage DrAverage Daily Traffic Volume: 4,700 near Ravensworth Rd,16,000 Near Little River Tpke

Speed Limit: 25 mph

Multiple schools and parkslocated along the corridor

Connection to the Cross CountyTrail


Heritage Dr• Ravensworth Road to Rectory Lane: 2 lane undivided, parking



Heritage Dr – Ravensworth Rd to Rectory Ln• Narrow lanes to include 2 travel lanes, 2 bike lanes, and 2

parking lanes (width shown includes gutter pan)


Existing Proposed


Heritage Dr• Rectory Lane to Little River Turnpike: 4 lane divided

• Parking would be retained where it exists today• Majority of corridor would remain with same configuration and bike

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)

• VDOT evaluating intersections for impact of changes to configuration



Heritage Dr• Rectory Lane to Patriot Drive: 4 lane divided



Heritage Dr• Rectory Lane to Patriot Drive: 4 lane divided

• Convert outside lane to buffered bike lane south of Patriot to beginning of median



Heritage Dr – Patriot Dr to 236• Patriot Drive to Little River Turnpike: 4 lane divided, parking



Heritage Dr – Patriot Dr to Little River Tpke• Narrow travel lanes, add bike lanes, keep parking


Existing

Proposed


Project Impacts


• Heritage Dr and Patriot Dr• Level of Service AM: before 18.4 seconds of delay, after 23.3 seconds

of delay• Level of Service PM: before 12.1 seconds of delay, after 14.6 seconds

of delay


• Bicycle Master Plan calls for sharrows, opportunity to do more and to add bike lanes through a road diet

• Existing 4 lane section, discussed at meeting last year, but was removed from 2015 repaving

• Proposal would be to implement a road diet• Convert to one lane in each direction, center turn lane, bike lanes

Speed Limit: 25 mph


McWhorter Pl – Ravensworth Rd to Markham St

Markham St• From McWhorter Pl to Little River Turnpike

• Bike Master Plan calls for bike lanes

• Proposal would be to implement a lane diet• Restripe roads and narrow lanes to provide space for bike lanes



Markham St



Speed Limit: 25 mph


Markham St – McWhorter Pl to Little River Tpke


Existing Proposed


Project Impacts


• Ravensworth and John Marr Drive• Ravensworth and McWhorter Place• Markham and McWhorter Place

Next Steps


• Gather community input tonight and over next two weeks• Comment Period Open until Friday, April 8th

• [email protected]

• Refine design plans as necessary• Design completion: May 2016• Projects go to construction Summer 2016
