MULTIMODAL ACCESSIBILITY

NEXT STEPS

Arlington County / Metropolitan Washington

Council of Governments (MWCOG)

Transportation-Land Use Connections Program

Addressing local agency and community

challenges (complete streets inventory)

Furthering transferable approaches (Multimodal

Accessibility)

Quick-response, six-month study

Complementary to / supportive of LHA initiatives

STUDY CONTEXT

BACKGROUND

3

Five study tasks:

Conduct SWOT analysis

Develop Multimodal Accessibility scores

Identify potential improvement costs/benefits

Develop inventory of potential improvements

Review, refine, report

STUDY CONTEXT

PROCESS

4

Transportation recommendations

Tier 1: Near-term, public sector

Tier 2: Near-term, private sector

Tier 3: Longer term

Our study will help identify what’s needed now in

Tiers 1 and 2 as well as set the stage for LHA and

County collaboration on placemaking concepts to

inform the function, design, and scale of Tier 3

improvements over time.

STUDY AREA

INTRODUCTION6

I-66 to North Lexington

~ LHA Areas 2 and 3

Focus on Lee Highway and parallel Old Dominion Drive

Consider community access

STUDY AREA

VDOT Principal Arterial (following US 29)

4-lane divided typical section

30 MPH posted speed

20K – 25K average weekday traffic volumes

1,100 total daily transit boardings

449 crashes from 7/2009-6/2013

EXISTING CONDITIONS REVIEW

EXISTING CONDITIONS7

SIGNALS AND SHELTERS


Aging equipment

Many bus stops lack shelters

Pedestrian signals throughout corridor

Crosswalks fairly well marked

CRASHES


449 in five year period

Spread throughout corridor

72% rear end and angle

3% alcohol/drug impaired

No fatalities

Crash rates themselves don’t indicate significant safety problems

SWOT >>>> RECOMMENDATIONS

SWOT ANALYSIS34

How do we move from SWOT to recommendations?

By considering:

Projects already underway (Tier 0?)

Benefits and costs of ideas / concepts

Planning for land use and infrastructure synergy; LHA and Arlington next steps in the fall will help guide long-term (Tier 3) concepts

The current study will focus on an inventory of near-term (Tier 1 and Tier 2) improvements


SWOT ANALYSIS35

SWOT ANALYSIS38

COULD WE FIT EVERYTHING IN?

Better sidewalks

Street trees

Bike lanes

Left turn lanes

On street parking


SWOT ANALYSIS39

COULD WE FIT EVERYTHING IN?

How much width?

How much length?

How compatible with other desired elements?


SWOT ANALYSIS40

Focus inventory on Tier 1 and Tier 2 near term spot improvements

Bus shelter needs

Pedestrian crossings

ADA concerns

Access to nearby neighborhoods

“Target speed” and placemaking opportunities

Frame discussion for mid-term to long-term improvements through continuing LHA and Arlington County planning activities

Test Tier 3 ideas at fall charrette

Analytic approach to measuring complete streets performance:

Access in addition to mobility

Proximity in addition to speed

Process for considering both land use and transportation improvements in planning and programming

Opportunity to consider auto, transit, and walk/bike travel across a common platform

Means for communicating travel propensity

WHAT IS MULTIMODAL ACCESSIBILITY?

MULTIMODAL ACCESSIBILITY41



Reflects both destination opportunities and travel time costs

Varies by mode of travel

Relationships can predict amount of walking, biking, and transit



Accessibility =

Where:

OPPORTUNITIES = Number of

Jobs (HBW) or Number of

Retail/Service Establishments

(HBNW)

TRAVEL TIME = Time to reach

opportunity over actual network

(Network Analyst)

DECAY = Factor reflecting

decrease in value of opportunity

that are farther away



LEE HIGHWAY APPROACH

Focus on community-serving retail in corridor

How accessible is the corridor by different modes?

Where are the “theres” there?

INITIAL FINDINGS


Where to walk to:

Fairly strong commercial centers between Glebe Road and Harrison Street

MMA score (similar to Walkscore) affected by retail presence and street grid

Retail Establishments and Walk Trip Attractiveness

INITIAL FINDINGS


Where to walk from:

Housing unit focus in Maywood / Cherrydale

Walk mode share related to MMA score (where to walk to)

Next steps: consider walk desire lines

Residential Population and Walk Trip Generation

Near term improvements (Tiers 1 and 2)

Discussion today

Potential improvements in May

Review, refine, report in June

Longer term improvements (Tier 3)

Discussion today

Concepts for LHA / Arlington coordination in fall

What is the vision for the corridor?

How should both the public/private realm feel and function?

Which policies may need to be revised to enable the vision?

FACILITATING THE CORRIDOR CONVERSATION

Integrating land use and transportation system objectives

- VDRPT Multimodal System Design Guidelines

- Establishing an integrated land use and transportation vision

- Defining the multimodal system and modal emphasis

- Developing appropriate treatments for Lee Highway

FACILITATING THE CORRIDOR CONVERSATION – LONGER TERM

NEXT STEPS48


NEXT STEPS49

Establishing corridor vision

- Land use density/diversity

- Corresponding transit mode functions and opportunities

- Layered network approach to Multimodal System

- Defining the Lee Highway role


NEXT STEPS50

Defining the multimodal system plan

Synthesize regional and local perspectives

Consider Level of Service requirements and Quality of Service objectives

Inform identification of modal emphasis for Lee Highway and other parallel and intersecting streets


NEXT STEPS51

Designing appropriate street treatments

- Consider public and private realms in tandem

- Allocate space based on modal priority and other considerations

- Consider balance between design standard minimums and optimal treatments
