The Department of Transportation has released a new version of the Freight Analysis Framework, a comprehensive data set on freight movement. The Freight Analysis Framework includes data on the amount and types of goods moved by land, sea and air between large metropolitan areas, states and regions. The map below shows the tons of freight moved by highway (red), rail (brown), and water (blue), with the thickness of the lines corresponding to the amount of freight moved. The rail network moves significant tonnage in the Midwest, while the lower Mississippi River carries the most freight tonnage over the water. Freight tonnage moved by highway is the heaviest in the Eastern third of the United States. The Freight Analysis Framework data set is available for download.
