1 Feasibility of a Metropolitan Truck-only Toll Lane Network: The Case of Atlanta, Georgia Michael D. Meyer, P.E., Professor School of Civil and Environmental Engineering Georgia Institute of Technology

2 2 TOT Study High level proof-of-concept analysis Not an exhaustive list of options Analysis based upon… –Available regional truck travel data –HOT lane study analysis methods –Assumed facilities (engineering feasibility not examined.)

3 3 HOT/TOT Steering Committee Atlanta Regional Commission (ARC) Federal Highway Administration (FHWA) Georgia Department of Transportation (GDOT) Georgia Regional Transportation Authority (GRTA) State Road and Tollway Authority (SRTA) Georgia Motor Trucking Association American Transportation Research Institute Industry representatives (United Parcel Service, Lithonia Lighting, Drug Transport, Inc.) Steering Committee

4 4 Congestion in 2030 Afternoon Peak (PM) Map Legend: Projected GP Congestion Levels in 2030 Highway GP lanes at capacity/congested Highway GP lanes near capacity Highway GP lanes with capacity available

5 5 The Opportunity & a Challenge Most HOV corridors have excess capacity But some HOV corridors will be congested Map Legend: Projected HOV Congestion Levels in 2030 PM Peak HOV lanes at capacity/congested HOV lanes near capacity HOV lanes with capacity available

6 6 HOT and TOT Study Primary Assumptions 2030 target analysis year Managed lanes network on all limited access facilities –One lane in each direction inside I-285 –Two lanes in each direction on and outside of I-285 Scenarios evolved based on expected performance levels and ability to handle demand at reasonable levels of service. TOT Assumptions

7 7 TOT Lane Objectives “MANAGE” the new lanes…Building to achieve --- Free flow conditions for managed lane users Free flow conditions for the region’s planned BRT network Maximum use of the highway capacity

8 8 Why Interested? Trucks constitute significant portion of highway flows Trucks take up a lot of space (capacity) Logistics industry in Atlanta region is significant and likely to grow Growth in national economy suggests tremendous growth in through truck trips Truck/auto crashes

9 9 TOT Assumptions Voluntary use of TOT lanes Value of time: –$35/hr for heavy trucks (over 8,000 lbs.) –$18/hr for light trucks Fees charged when needed and in the amount needed to manage performance of TOT lanes Conservative passenger car equivalents used (1 truck = 2 cars) Truck lane interchanges provided at HOV interchanges for initial assessment Buses can use TOT lanes as well

10 10 Three Alternatives Evaluated Alternative 1: TOT lanes are established along side of planned HOV lanes. Alternative 2: Same as above, PLUS in midday hours (10am-3pm) light service trucks can use HOV lanes inside I-285. Alternative 3: TOT lanes are established in place of planned HOV lanes along I-285 and outside of I-285.

11 11 Alternative 1 Voluntary TOT –I-75 N –I-85 N –I-285 –I-75 S HOV network –Entire region Voluntary TOT –I-75 N –I-85 N –I-285 –I-75 S HOV network –Entire region North-South East-West

12 12 Alternative 2 Current HOV lanes inside I-285 restricted to light duty trucks in midday Current HOV lanes inside I-285 restricted to light duty trucks in midday

13 13 Alternative 3 Voluntary TOT –Outside I-285 –On I-285 HOV network –Inside I-285 only TOT replaces HOV outside and on I-285 Voluntary TOT –Outside I-285 –On I-285 HOV network –Inside I-285 only TOT replaces HOV outside and on I-285

14 Truck Productivity TOT Scenarios

23 23 ARC modeled air quality impact and found little change in expected emissions, however…. Safety benefits are potentially huge ($3 million per fatality, not to mention delay costs) Air Quality and Safety

25 25 Improved freight and passenger movement –Regional travel time saving (for all, except HOV users) –More reliable travel conditions –Safer travel conditions (we believe) Efficient –Truck operators save time, increase productivity –Regionally, similar vehicle miles traveled in fewer hours Potentially cost effective –Opportunity to offer substantial benefits, earn revenue What We Learned About TOT Lanes
