Agenda

• • • • • What are Managed Lanes?

Managed Lanes in Georgia – Where we were – Where we are – Where we are going Managed Lane Strategies Prioritization of Managed Lane Projects Next Steps

What are Managed Lanes?

Managed Lanes in Georgia WHERE WE WERE

2009 Atlanta Regional Managed 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

2009 Managed Lane System Plan Goals

Managed Lanes in Georgia WHERE WE ARE

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

Managed Lanes in Georgia WHERE WE ARE GOING

New Planning Assumptions Moving Forward

• 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

Managed Lane

Implementation

(MLIP) Plan

• • 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 – Typical Section BEFORE

Shoulder Lanes – Typical Section AFTER

Shoulder Lanes - Case Studies Shoulder Sign in Washington State

• • • • 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 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

Managed Lane Strategies MOVEABLE BARRIERS

Moveable Barriers – Typical Section BEFORE

Moveable Barriers – Typical Section AFTER

• • • • • •

Moveable Barriers - Case Studies I-93 Reversible Lanes in Boston

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
