Abstract
Improvements in truck freight efficiency through such measures as optimized logistics and truck loading, the utilization of other transportation modes, and the reform of federal truck size and weight policy are expected to require fewer truck trips to move the nation’s freight. This reduction in truck travel distance should bring with it reductions in fuel consumption, emissions, and casualties as a result of reduced exposure. This paper discusses truck size and weight policy domestically and internationally and contrasts U.S. mass efficiency with that of the country’s North American Free Trade Agreement partners and, more broadly, with countries outside of North America. The analysis reveals the outdated nature of U.S. federal size and weight policy compared with other nations. The inability of U.S. federal policy to remain current with other countries is a result of a freeze on policy change that has been in place since 1982. An analysis of the societal benefits associated with improvements in truck freight efficiency is provided. Rather than estimating the precise benefits associated with the many options available, the analysis examines the benefits associated with a 10% reduction in truck travel distance. In this way, the paper provides insight into the significance of improved freight efficiency that reduces total truck travel distance, which in turn provides fuel savings, a reduction in emissions, and a reduction in truck crash frequency. The analysis concludes that a 10% reduction in truck distance traveled for a fixed national freight task would generate approximately $16 billion, save 330 lives, and prevent approximately 4,000 injuries per year.
