The report provides an overview of freight movement on the U.S. transportation system today and in the future. It discusses where the largest freight flows are concentrated and the pressures that existing and anticipated freight volumes place on the system. Special attention is given to freight congestion and its effects on highways, railroads, and waterways. The economic costs to shippers, carriers, and the overall economy also are examined. Finally, the report describes government and private sector efforts to improve freight transportation and mitigate the safety and environmental effects of growing volumes of freight. |
