This 11th edition of Freight Facts and Figures was developed by the Bureau of Transportation Statistics. It provides a snapshot of the volume and value of freight flows in the United States; the extent, condition, and performance of the physical network over which freight moves; the economic conditions that generate freight movements; the industry that carries freight; and the safety, energy, and environmental implications of freight transportation. This snapshot helps decisionmakers, planners, and the public understand the magnitude and importance of freight transportation to the economy. |
