  1. Manitoba Trucking Efficiency Initiative

  2. Context • Manitoba Energy Use 300 PJ total energy used 200 fossil fuel energy used 100 energy used for transportation energy used to transport freight by road 1990 1995 2000 2005 2010

  3. 12 Mt CO2e 9 6 3 0 1990 1995 2000 2005 2010 Context • Manitoba Greenhouse Gases greenhouse gases produced GHGs produced by road freight transport 1990 1995 2000 2005 2010

  4. 10 billion tonne-kilometers 8 6 4 2 1990 1995 2000 2005 2010 Context • Manitoba Road Freight Transportation

  5. 5 MegaJoules per tonne-kilometer 4 3 2 1 0 1990 1995 2000 2005 2010 Context • Manitoba Road Freight Energy Efficiency

  6. Proposal • “Opportunities to Partner with the Manitoba Trucking Industry on GHG Reduction” • Prepared in response to “Tomorrow Now, Manitoba’s Green Plan”, a policy document of the Government of Manitoba. • Co-authored and jointly submitted by the Manitoba Trucking Association and 50by30. • Submitted April 2014 to Manitoba government

  7. Proposal - Goal • “double-green” • increase potential for profit in Manitoba trucking industry by improving efficiency • reduce MegaJoules per tonne-kilometer • reduce GHG emissions from road freight transportation • in Manitoba • everywhere Manitoba trucks haul freight

  8. Proposal - Elements • Regulatory • Long Vehicle Combinations • New Generation Wide-Base Tires • Full Length Boat Tails • Fiscal • PST exemption on aftermarket purchases • Grants defraying part of the cost of fuel-efficiency technologies • Loan guarantees or a PAYS-like program

  9. 2. New Generation Wide-Base Tires • goal: to permit NGWBT on select MB roads • all roads classified by MIT as RTAC routes • http://www.gov.mb.ca/mit/mcd/mcpd/mhcs.html • by “NGWBT” we mean 445 & 455, or wider

  10. 2. New Generation Wide-Base Tires • Material reviewed: • Pierre et al. (2003) “Characterization and Evaluation of Tire-Roadway Interface Stresses” (a translation of “The Laval Study”) • U.S. Environmental Protection Agency (2004) “Single wide-based tires” • Al-Qadiet al. (2004) “Pavement damage due to different tires and vehicle configurations” • Bachman et al. (2005) “Effect of single wide tires and trailer aerodynamics on fuel economy and NOx emissions of class 8 line-haul tractor-trailers” • Knowles & Synectics(2008) “Analysis of the economic costs and benefits related to increasing the Ontario weight allowance for new-generation wide base single truck tires” • Ponniah& Hass (2008) “Single wide-base tires in Ontario: Potential pavement damage cost analysis” • Al-Qadi & Wang (2009) “Evaluation of pavement damage due to new tire designs” • Surcel& Jokai (2010) “Evaluating components of the Canadian Trucking Alliance's enviroTruckconcept” • Grelletet al(2013?) “Comparison between wide base single tire and dual tires assembly based on experimental pavement response and predicted damage” • Weaver et al (2011-2015) “The impact of wide-base tires on pavement damage: A nationalstudy”

  11. 2. New Generation Wide-Base Tires

  12. 2. New Generation Wide-Base Tires • Effect on pavement, best current knowledge: • Al-Qadi & Wang (2009) “Evaluation of pavement damage due to new tire designs” • https://apps.ict.illinois.edu/projects/getfile.asp?id=3007 • Wide-base tire causes greater fatigue damage and subgrade rutting than dual-tire assembly • However, the relative damage ratios between various configurations at the same load decrease as the pavement thickness increases. • Wide-base tire causes less top-down cracking, “near-surface” cracking, and HMA rutting damage than dual-tire assembly • Using a wide-base 455 tire results in the least amount of pavement damage for an interstate road, slightly greater damage for a primary road, and more damage for a local road.
