1. A Status on Large Scale Truck Separation in the United States Presentation to: FHWA’s Talking Freight Seminar on Truck Separated Lanes/Truck Tolling March 16, 2005 Arno Hart Wilbur Smith Associates

2. Various Concepts Grade Separated New Mixed-flow or HOV Lanes Tolled Truck Lanes Truck Climbing Lanes

3. State DOT’s are starting to recognize……. State DOT’s are starting to recognize……. Need for additional freight capacity on highways

4. Scenario 7: Truck Productivity Scenario 3: Truck/Auto Separation Scenario 4: Multimodal Rail Corridor Scenario 5: Multimodal Waterway Corridor Scenario 6: Urban Truck Bypass Scenario 2: ITS Scenario 1: Widening Potential Strategies National I-10 Freight Corridor

5. New freight policy directions…. Also need policies to ACCOMMODATE trucks Truck traffic is expected to grow Despite need for continued focus on modal DIVERSION 1.Innovations in highway development 2.Innovations in truck mobility/operations

21. Maximum Corridor ROW Width

22. Truck Component   May be enough long-haul truck volume to support southern segment from Seattle to Oregon, but would require some public funding   To be financially feasible, a two-lane truck-toll highway south of Seattle would need to divert 50% of long-haul trucks from I-5. Trucks could pay up to a $60 toll (about $0.60/mile)
