TRANSPORTATION SOLUTIONS: GETTING THE MOST BANG FOR YOUR BUCK! GPA Fall Conference 2013 Kyle Mote GDOT Office of Planning October 10, 2013
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
Managed Lanes in Georgia WHERE WE WERE
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
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 AssumptionsMoving 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 ImplementationPlan (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 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 SR 400 Shoulder Lane (Atlanta, GA) Source: www.itsinternational.com 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 - Case Studies I-93 Reversible Lanes in Boston Source: Barrier Systems, Inc. • 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 Source: Barrier Systems, Inc. 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
Corridors Selected forMoveable Barrier Evaluation Limited Shoulders Directional Split, MARTA Rail Arterial, Grass Median Directional Split Grass Median Limited Shoulders Grass Median
