Agenda

• 2009 Managed Lane System Plan overview
• Current activities: Managed Lane Implementation

Plan

• Lessons learned and emerging findings
• Next steps

2009 Atlanta Regional Managed Lane System Plan (MLSP) - Overview

• First regional managed lanes

plan in the country

• In 2009, there were no Priced

Managed Lanes in the Atlanta region (only HOV lanes)

• Identified $16 Billion in MLs
• Assumed $9 Billion could be

delivered via PPP

• $5.9 Billion programmed in

current Atlanta MPO Plan

2009 Managed Lane System Plan Goals

• Protect mobility with all new capacity
• Maximize person/vehicle throughput
• Minimize environmental impacts
• Provide a financially feasible system
• Design and maintain a flexible infrastructure

network, for varying lane management

Managed Lane Corridors Currently in Operation or in Development (Priced & HOV)

• Open to traffic:

– I-85 North Express Lanes (16 miles)

• HOV2+ to HOT3+ conversion in 2011
• 250,000 transponders issued
• Under Development:

– Northwest Corridor (I-75/I-575 North) Express Lanes

• ROD issued May 2013

– I-75 South Express Lanes

• Expect FONSI, summer 2013

– I-85 North Extension

• Construction currently planned for FY 15
• In the Alternative Evaluation Process:

– I-285 Top End (revive285)

• EIS under development

– SR 400 North of I-285

• Feasibility study underway

Existing & Planned Priced Managed Lanes

• All limited access highway new capacity in Metro

Atlanta will likely be tolled

• Remove HOV2+ to HOT3+ conversions from MPO

TIP

• Eliminate assumptions of long-term concession

agreements

• Evaluate lower-cost managed lane treatments

New Planning Assumptions Moving Forward

Managed Lane Implementation Plan (MLIP) Overview

• Updating MLSP as part of Managed Lanes Implementation Plan

(MLIP) to:

– Build upon previous MLSP goals – Reflect current funding constraints – Identify feasible locations for managed lane projects – Redefine and reprioritize projects from the previous plan based on current and future needs – Prioritize list of managed lane projects and accompanying financing strategies (P3 and traditional funding sources)

• Incorporate recommendations into RTP and TIP update, as

appropriate during 2013-2014

Innovations and Emerging Findings-MLIP

• Considering non-traditional Managed Lane solutions

– Reversible lanes

• Moveable barrier (new option)
• Fixed barrier (existing option)

– Shoulder lanes

• Consider managing inside lane in peak periods and off-setting the

removed general purpose capacity with travel on shoulder

– Option: use reversible barrier and shoulder lanes in conjunction with each other

• Intent is to not “reduce” current travel options for

motorists

Shoulder Lanes – Case Studies

• Washington State - US 2

– 1.5 miles during PM only

• Minneapolis

– 3.0 miles during AM & PM – Use left shoulder – Region wide bus shoulders

• UK M42 Highway

– 10 miles – Shoulders used in conjunction with variable speed limits

• Netherlands

– Use left and right shoulder

Shoulder Sign in Washington State

Shoulder Lanes – Considerations

• Shoulder pavement depth
• Shoulder width
• Bridge spans and pillar

locations

• Entrance/exit ramp

locations and volumes

• Additional signage
• Refuge sites (incidents and

emergency access)

• Segment length

Shoulder Lanes-Lessons Learned

• Manage expectations, not all shoulders lend

themselves to travel

• Capital costs vary dramatically based on existing

infrastructure

• Develop active traffic management system concept

Shoulder Lanes-Lessons Learned

• Pre-determine enforcement roles/processes,

incident response, training, public outreach and education

• Strategic placement of video cameras to monitor

traffic

• Strategic placement of emergency refuge areas,

with proper signing

Moveable Barriers

Moveable Barriers – Case Studies

• I-30/Thornton Freeway: Dallas, TX
• 5.2 mile managed lane during AM & PM
• Increased speeds from 22 to 41 mph
• 1,200 – 1,400 vehicles per hour (vph)
• I-93: Boston, MA
• 6.0 mile managed lane during AM & PM
• Flows at posted speed (55 mph)
• 1,500 - 1,800 vph
• No increase in accidents
• I-70: West of Denver, CO
• 13.5 mile EB Sundays
• Significant decrease in EB travel times (79 to 41

min.) and increase in WB travel times (34 to 69 min.)

• 2% annual increase in crashes (snow conditions)

Moveable Barriers – Considerations

• Directional split of traffic and number of lanes
• Estimated benefit (travel time savings)
• Capital and Operating & Maintenance costs
• Bridge spans and pillar locations
• Median and/or shoulder widths
• Borrow inside lane or shoulder for reverse direction and/or widen

to the median

• Logistics of rev. lanes
• Additional signage
• Segment length

Source: Barrier Systems, Inc.

Moveable Barriers-Lessons Learned

• Plan ahead (traffic impacts, physical limitations,

storage, etc)

• Develop standard operating procedures
• Enforcement (if operated as managed lane)
• Public education
• Dependable contractor (if operation is privatized)

Moveable Barriers-Lessons Learned

• Spare parts inventory
• Aggressive preventative maintenance
• Adequate staffing for enforcement, traffic incident

management and maintenance

• Consider multiple access points

Priced Managed Lanes

Georgia Priced Managed Lane Overview

• High Occupancy Toll (HOT)

– Mixture of occupancy and tolling components – 17 currently in operation across US, including 1 in Georgia (I-85 North) – Relatively easy to convert HOV lanes to HOT (need public support) – Requires additional enforcement/back office operations – Transit buses have free access

• Express Toll Lanes (ETL)

– All users pay (except transit buses) – 1 currently in operation in US (SR 91, CA), 2 planned in Georgia (I-75 South & I-75/I-575 North) – Easier to enforce/back office operations, when compared to HOT – Higher revenue than HOT

Priced Managed Lanes – Case Studies

• High Occupancy Toll (HOT) Lanes

– I-95: Miami, FL – SR 167: Seattle, WA – I-15: Salt Lake City, UT – I-394: Minneapolis, MN – I-10 Katy Freeway: Houston, TX

• Express Toll Lanes (ETL)

– SR 91: Orange County, CA

Priced Managed Lanes

Priced Managed Lanes-Lessons Learned

• Tolling existing capacity (HOV and GP) can be

challenging

• Likely not self-supporting, requiring funding

source, particularly in early years for O&M

• Recognize ramp-up period for tolling, adjustment

time for motorists

• Interface between differing managed lane types

(HOV to HOT) has been less of an issue than anticipated in MLSP

Priced Managed Lanes-Lessons Learned

• Ideally provide users with travel time estimates

and speed limits in using dynamic signs

• Complete camera coverage aids in operations and

enforcement

• Occupancy detection, declaration and

enforcement impact revenues

Priced Managed Lanes-Lessons Learned

• Access points may need modification after open to

traffic

• Design and operation should be flexible enough to

accommodate fluctuating traffic patterns

• Adequate signage is necessary to identify access

points

• Evaluate potential funding resources early

Priced Managed Lanes-Lessons Learned

• Effective outreach is essential and must continue

throughout project planning, implementation, and

• peration:

– Reliable/faster trips – Transit access – Increased network capacity – Limited ability to build additional general purpose lane capacity – HOV can be an ineffective way to regulate demand

Priced Managed Lanes – Emerging Trends

• Multi-lane facilities
• Dual purpose investments (auto and transit)
• Regional network
• Develop performance measures (speeds,

throughput-both car and transit)

• Moving from HOT based facilities to ETL facilities,

with new construction
