ns
• Metrorail expansion to
Dulles Airport
• Policy of higher density,
mixed use development
in activity centers
• Tysons is not sustainable
as exists today
• 17,000 residents to
105,000 jobs
• 167,000 parking spaces
5
Tyso
ns The Vision
A livable urban center with:
– Transit-oriented
development
– A variety of modes for trip
making
– Fewer parking spaces
– Pedestrian and bicycle
friendly streets
– A defined “sense of place”
throughout Tysons
– Residents to Jobs mix of
100,000/200,000

Memorandum
of Agreement (MOA) and
ns
Transportation Design Standards for Tysons
•
•
•
Set up to implement the design
standards and address permitting
and maintenance issues
Developed by Fairfax County and
VDOT with input from numerous
stakeholders
Purpose
– Develop a platform by which the
Tysons Comprehensive Plan
could be implemented
– Facilitate the provision of
transportation facilities that
accommodate low speed
roadways, pedestrian and bicycle
facilities and transit services
11
Tyso
Tysons
ns Memorandum of Agreement –
Responsibilities
•
•
•
•
VDOT
Review and approve plans using
Tysons Standards
Accept new streets that conform
to VDOT and Tysons Standards
including phased and stubbed
streets
Issue permits for work to be
performed on the streets
Maintain existing and future
streets that have been accepted
into the primary and secondary
system
•
•
Fairfax County
Ensure that the development is in
conformance with the Tysons
Standards
Ensure that access rights are
provided on any new street
constructed as a phased or
stubbed street to allow for
maintenance and public safety
vehicles to turn around safely
12

Tysons
ns MOA – Non-Standard Features
•
•
The placement of non-standard features
within the ROW are subject to VDOT
review for safety and operational issues
Such facilities when approved shall be
subject to the following:
– Non-standard feature should be allowed
only through the issuance of a permit by
VDOT
– Permittee may be Fairfax County or
private developer
– VDOT is not obligated to construct,
install, operate, maintain or replace any
such feature
– Features will be operated and
maintained by the holder of the VDOT
permit

3. Special landscaping materials, planting beds, raised
planters, street trees, root cell structures, tree cages
and other landscaping materials

ns Level of Service Standards
(1)
(2)
The minimum designated standard for NHS designated streets is D, while the standard in the Tysons
Comprehensive Plan is E. The VDOT District Administrator may accept a lower standard for NHS
routes upon review of an Operational Analysis. Where LOS D/E cannot be achieved, mitigation
measures must be considered. A LOS Waiver is required and is administered by the VDOT District
Administrator.
Where LOS E standard cannot be achieved, mitigation measures must be considered. LOS Waiver is
not required.

Tyso
Level of Service (LOS) Standards
ns
•
•
•
The vehicular LOS needs to be
balanced with a high LOS for
walkability, cycling and transit
The LOS needs to be balanced
with economic development
objectives
To provide the balance, it is
necessary to apply the tiered
approach where the location
does not meet the LOS
standard
17
Tyso
LOS Tiered Approach
ns
1.
2.
3.
4.
5.
6.
Analyze the location not meeting the LOS standard providing
aggressive TDM or multi-modal mitigation measures
Evaluate whether additional grid links can be constructed
Consider temporary traffic mitigation measures
Determine whether an acceptable balance has been achieved
between vehicular LOS and pedestrian, cycle and transit mobility
If acceptable balance has not been achieved, make land use
adjustments
If acceptable balance has not been achieved, consider turn lanes
to improve LOS without seriously compromising pedestrian, transit
and bicycle mobility
18
Tyso
ns Design and Operating Speed
• Tysons uses a modified functional classification
• Design speed is primary control for:
– Minimum intersection sight distance
– Minimum sight distances on horizontal and vertical
curves

Access Management
ns
•
•
•
Existing intersections are exempt
Intersection spacing represents min and max to help
implement the street grid
It is very important to plan for Access Management early in the
development process
20
Tyso
nsDesign and Control Vehicles for
Designing Street Intersections
•
•
Design Vehicle is one that must be accommodated without
encroachment into the opposing traffic lane
The Control Vehicle is:
– Infrequent
– Must be accommodated:
•
•
•
By allowing encroachment into opposing lanes or
Minor encroachment into the streetside area or
As a last option multiple-point turns of vehicle

CTIA Process
Stakeholder outreach and participation
Consensus on grid to be studied
VISUM
Tiered approach
– Minimizing ROW needs
– Balancing pedestrians and vehicles
– Focus on intersections with highest delay
• Rounds of mitigation
• Consensus of improvements needed
• Documentation and VDOT review
24
Tyso
ns
Use of CTIA
• Baseline for reviewing transportation
improvements and proposed grid of streets
• Set expectations for development community
• Traffic information that can be used to refine
larger infrastructure projects.
25
Tyso
ns
Lessons Learned
• MOA and Design Standards has helped the
review and approval process
• CTIA helped development of baseline
• There is always a need to provide additional
clarifications
• Addition of stakeholders complicates the
process but is critical to buy in
• VDOT and Fairfax County don’t always interpret
the standard the same way but coordination
makes it work

Questions?
27
Tyso
nsTransit Infrastructure Circulator
• The Tysons Circulator
Study identifies the
internal routes to serve
Tysons
• Portions of these routes
will be on exclusive
circulator lanes
• Identification of
circulator stations critical
for coordination with
development
28
Tyso
ns Transit Infrastructure - Metro
• The Metrorail Silver Line
includes four stations in
Tysons
• Some pedestrian and
bike facilities to
enhance connections to
Metro stations may not
be provided until
redevelopment

nsPurpose of Re-Planning Tysons
• Link land use planning to investments in
transportation (Metro, circulator, ped and bike
facilities)
• Regional growth management strategy to
concentrate development in activity centers
• Reduce vehicle trips by providing multimodal
options

feet near Metro, lower in
surrounding neighborhoods
• Build to Line (maximum
setback rather than min
setback requirement)

accommodate existing
leases at redevelopment
sites

Tyso
Parking (continued)
ns
• Additional parking on a site
not required with a change
in land use
• Temporary parking facilities
allowed near Metro stations
• Site plan approval for
temporary parking facilities
requires queue analysis for
the gates
