Presentation Transcript

  1. Perspectives on Sustainable Transport – Truck Productivity – Presented to Swedish House Seminar Series Moving the World: The Future of Freight Transportation John Woodrooffe December 1, 2010

  2. Safety Sustainable Transport *Policy* Efficiency

  3. Present time Policy Sustainability Index Safety Time Contributions to sustainable transport Federal, State, Company, Individual Operational Efficiency

  4. OECD Truck Benchmarking Study“Moving freight in better trucks” Compared the most common “workhorse” trucks and various high and very capacity vehicles from participating countries in terms of: Road wear performance Impact on road structures Safety performance (with a focus on vehicle design) Productivity (in terms of mass and volume) Environmental impacts (emissions, energy consumption)

  5. Defining truck productivity Productivity – how much freight can be hauled in a particular vehicle Note: Truck cargo capacity is limited by weight or volume (depends on freight density)

  6. Total energy used per hour (90 km/h, 44 tonne, level road for one hour) 343 kWh Aerodynamic Losses 53 kWh Engine losses 200 kWh Rolling Resistance 65 kWh Drive train 10 kWh Auxiliary loads 15 kWh Steady State Energy Balance

  7. Towards sustainable productivity Move as much freight as possible per power unit more safely than the current fleet with less infrastructure consumption

  8. Workhorse vehicle

  9. Workhorse vehicle North American context

  10. Key Message Truck productivity is limited by policy not technology

  11. 53 ft standard trailer 53 ft standard trailer LCVProgressive operations policy can yield substantial societal benefit

  12. What can advanced LCV policy do (on a per vehicle basis)

  13. Size and weight policy is frozen by politicsTo the extent possible let science guide policy

  14. Suggested policy changes for improved productivity and sustainability • Bring tandem and tridem axle loads more in line with international limits • Tandem from 34,000 lbs to 37,000 lbs • Tridem from 42,000 lbs to 50,000 lbs • Remove the arbitrary 80,000 lb cap on the Federal Bridge Formula • Update the bridge formula – it is antiquated

  15. Conclusions • Truck productivity is limited by policy not technology • Truck size and weight regulations directly influence transport productivity, efficiency, fuel use and emissions output • Such regulations represent a tool that not only protects the infrastructure but also encourage vehicles that provide significant societal benefits

  16. Thank You
