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
3
What are Managed Lanes?
4
Managed Lanes in Georgia WHERE WE WERE
5
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
6
2009 Managed Lane System Plan Goals
7
Managed Lanes in Georgia WHERE WE ARE
8
Managed Lane Corridors Currently in Operation or in Development (Priced & HOV)
9
Managed Lanes in Georgia WHERE WE ARE GOING
10
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 Assumptions Moving Forward
11
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
12
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
13
Managed Lane Strategies SHOULDER LANES
14
Shoulder Lanes – Typical Section BEFORE
15
Shoulder Lanes – Typical Section AFTER
16
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
17
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 SR 400 Shoulder Lane (Atlanta, GA) Source: www.itsinternational.com
18
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

Corridors Selected for Shoulder Lane Evaluation Limited Shoulders

Managed Lane Strategies MOVEABLE BARRIERS
21
Moveable Barriers – Typical Section BEFORE
22
Moveable Barriers – Typical Section AFTER
23
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) Source: Barrier Systems, Inc. I-93 Reversible Lanes in Boston
24
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.
25
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
