This study presents a macroscopic model for U.S. freight transportation, integrating mode choice and shipment size decisions. Utilizing 2012 Commodity Flow Survey and U.S. Census Bureau data, it employs a discrete-continuous econometric framework to address selectivity bias. The model aggregates commodities into classifications based on the North American Industry Classification System (NAICS) and the Standard Classification of Transported Goods (SCTG), providing a comprehensive description crucial for economically consistent freight mode selection. Numerical findings underscore the significance of commodity characteristics, NAICS, and geographic distribution in influencing joint decisions for nine modes of transportation, varying from a single mode to competition between two or more modes.
