2009 Atlanta RegionalManaged Lane System Plan (MLSP)
• 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• $5.9 Billion programmed in
current Atlanta MPO Plan

• All new limited access 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 AssumptionsMoving Forward

Managed Lane Implementation Plan (MLIP)
• 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
• Consider traditional managed lane solutions– New Lanes
• Considering non-traditional managed lane solutions– Shoulder lanes– Reversible lanes using movable barriers– Option: use reversible barrier and shoulder lanes in
conjunction with each other• Intent is to not “reduce” current travel options for
motorists

Managed Lane Strategies
SHOULDER LANES

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• Pre-determine enforcement roles/processes, incident
response, training, public outreach and education• Strategic placement of emergency refuge areas, with
proper signing• Strategic placement of video cameras to monitor traffic

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

Moveable Barriers - Lessons Learned
• Plan ahead (traffic impacts, physical limitations, storage, etc)
• Develop standard operating procedures• Public education• Spare parts inventory• Aggressive preventative maintenance• Adequate staffing for enforcement, traffic incident
management and maintenance
