New Report Details Priority Research Projects for U.S. Department of Transportation Regarding Truck Size and Weight Regulations

WASHINGTON – A new report from the National Academies of Sciences, Engineering, and Medicine presents a research roadmap to address gaps and uncertainties in estimating the impacts of proposed changes in truck size and weight limits -- the regulations that set the maximum weights, lengths, and numbers of trailers allowed for trucks on U.S. highways.  The report defined a program of 27 research projects focused on pavements, bridges, safety, enforcement, and shippers' decisions to transport freight by truck, rail, or other modes.  The U.S. Department of Transportation's Federal Highway Administration tasked the National Academies to develop a plan for a research program to reduce uncertainties in estimates of the impacts of changes in the limits.

The committee that carried out the study and wrote the report identified seven core research tracks, each made up of one or several projects, that have a good probability of producing useful results within a practical time period and budget and would significantly contribute to reducing uncertainty in truck size and weight limit evaluations.  The committee estimated that this core program could be completed within four to six years for $4 million to $6 million.  The core research tracks are:


The committee concluded that a targeted research program, plus improvements to data systems, would strengthen the federal and state governments' capabilities to project impacts of changes in truck regulations.  Of equal importance, the research could reveal opportunities to improve safety and productivity and control highway costs, regardless of whether truck size and weight limits are changed.

The study was sponsored by the U.S. Department of Transportation.  The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide independent, objective analysis and advice to the nation to solve complex problems and inform public policy decisions related to science, technology, and medicine.  They operate under an 1863 congressional charter to the National Academy of Sciences, signed by President Lincoln.  For more information, visit nationalacademies.org.  A committee roster follows.
