Study Area

Purpose of Study
• Conduct a detailed analysis of the grid of streets and
determine
– A finalized grid of streets
– Number of lanes between and at intersections
– How to best accommodate transit, bikes, and pedestrians
– Right-of-way needs
• Assign urban street types and modal emphasis
based on Department of Rail and Public
Transportation design guide lines
• Examine four specific locations in detail
5

How we got here:
Reston Phase I Plan Amendment
6

Need for Study
7
• The Reston Phase I Comprehensive Plan Amendment
was adopted by the Fairfax County Board of Supervisors
on February 11, 2014.
• The Board follow on motion from the adoption directed
staff to: “conduct a detailed evaluation and operational
analysis of the enhanced street network shown on the
Reston Master Plan, prioritize these improvements, and
develop an implementation strategy.”

Need for Study
Follow-on Study to the Reston Phase I Plan Amendment

Transportation Analysis
9
• Transportation study was done to determine what
transportation improvements are needed to support the
planned development in the TSAs
• Specific recommendations were made to enhance the
transportation network
• Phase I recommended, but did not analyze and optimize
the conceptual grid of streets

Major Transportation Recommendations
10
• Maintain a Balance between land use and transportation
• Ensure pedestrian mobility throughout the TSAs
• Bike Master Plan for County, including the TSAs has
been adopted
• An enhanced RIBS and Fairfax Connector service to
support rail
• Strong Transportation Demand Management (TDM)
program in the TSAs

Major Road Transportation Recommendations
11
• An enhanced street network
to increase connectivity
• Soapstone Drive Overpass
• Town Center Parkway
Underpass
• South Lakes Drive Overpass
• Grade Separate Fairfax
County Parkway/Sunrise
Valley Drive

Grid of Streets
12
• Conceptual grid of streets was a result of the Reston
Task Force
• The three TSAs were examined and had conceptual
grids developed by task force members
• These grids were refined by FCDOT staff
• The conceptual grid was then included in the
comprehensive plan

Why a Grid
A grid of streets allows for more options when going from
point A to point B, reducing the demand on streets

Evaluating the Grid
• Level of Service and Delay at Intersections
• Queue Length
• Walksheds – pedestrian accessibility
• Enhanced connectivity for transit
20

Transit Oriented Development
• Mixed-use walkable development around Metrorail
Stations
• Supported by strong TDM program
• Enhanced pedestrian amenities
• Increased transit ridership
• More bike parking and access
• Encourages carpooling
• Teleworking

• LOS measures peak hour
delay at an intersection or how
well traffic moves along a
roadway.
• LOS E is the standard for the
Reston Transit Station Areas

Mitigation Measures
• Mitigation reduced delays experienced at intersections
• Mitigation reduces vehicle congestion
• Mitigation improves the reliability of travel times
through an area (for both buses and vehicles)
• Mitigation will be the way we achieve LOS E in the
Transit Station Areas
24

Mitigation Options
• Mitigation Measures - Tiered Approach
– 1st Tier: No right of way impact
– 2nd Tier: Some right of way impact
– 3rd Tier: Large scale mitigations if needed
– Consultation with Advisory Group and
Stakeholders
• Each grid link is initially assumed to be one
lane in each direction
25

Mitigation Measures
1st Tier: No Right of Way Impact
•Intersection Reconfiguration
– Optimized signal timing and phasing
– Lane configuration modification

Mitigation Measures (Cont.)
1st Tier: No Right of Way Impact
27
•Existing and Potential Future Signals
– Adding/removing traffic signals
– Adding/modifying stop control
– Modifying Parking

28
Mitigation Measures
2nd Tier: Some Right of Way Impact
• Turn lanes
– Left and Right turn lanes
– Add storage
– Reduces queuing on to through movement
• Additional through lane
• Additional grid link

Mitigation Measures
3rd Tier: Alternative Intersection Treatment
• Median U-Turn/Superstreet
– Eliminate left turn movement for side streets
– Increases thru movement green time
– Additional needed ROW to provide turn radius
29

Mitigation Measures
3rd Tier: Large Mitigation Measures
• Underpass/Overpass
– Provides for an uninterrupted thru movement
• Only done in close coordination with Advisory
Group and Stakeholders after all other mitigation
measures have not worked

• The Board follow on motion from the adoption included
the Planning Commission recommendation to conduct:
“an inclusive process to prepare a funding plan for the transportation
improvements recommended in the Reston Master Plan and report
with its recommendations. The funding plan should include
arrangements for financing the public share of Reston infrastructure
improvements and facilitate co-operative funding agreements with
the private sector. The PC strongly believes that public and private
investment in Reston is both critical and responsible for ensuring
Reston’s future success”

Reston Funding Plan (Cont.)
