Understanding how freight moves now predicting how it might flow in the future are essential to transportation planning that meets the need for efcient, safe, and economical freight movement. The Federal Highway Administration (FHWA) Exploratory Advanced Research (EAR) Program is supporting freight transportation research that will develop tools to accurately model future freight demands and devise new methods of freight data collection. Resource Systems Group, Inc. (RSG), with research partners at the University of Washington and the University of Toronto, launched the “National Freight Demand Model” project. It will allow decisionmakers to understand better the factors that influence freight movement on scales ranging from interurban commercial deliveries to regional and national infrastructure needs.
