摘要

Truck transportation efficiency including fuel consumption and greenhouse gas production perunit of freight transported is directly influenced by truck size and weight policy. This papercompares the cargo mass productivity of U.S. workhorse articulated vehicles with those fromother developed nations in relation to allowable axle loads and GVW. The U.S. IntermodalSurface Transportation Efficiency Act (ISTEA) of 1991 limited the gross vehicle weight to80,000 lbs which has constrained vehicle mass to the point that within the NAFTA region, theU.S. vehicle mass productivity deficit for tractor semitrailers is 43% compared with Canada and52% compared with Mexico. The paper provides a summary of the history of U.S. truck size andweight policy and concludes with the following questions.1) Is the U.S. infrastructure strength significantly weaker than that of other developed countries?2) What is the cost to the nation, to the environment and energy supply for the apparent lack oftransportation efficiency?3) Why does the U.S. not have an integrated national transportation policy to optimizetransportation efficiency?4) Have lower axle and gross vehicle weights resulted in fewer fatalities or has the greatervehicle exposure attributed to transportation inefficiency resulted in more fatalities?
