Maps, Data, and Tools
Freight Analysis Framework (Federal Highway Administration)
FAF integrates data from a variety of sources (including the Commodity Flow Survey) to create a comprehensive picture of freight movement among states and major metropolitan areas. The tool estimates tonnage, value, and domestic ton-miles by region of origin and destination, commodity type, and mode for current and forecasted years.
Freight Facts and Figures – USA
Freight Facts and Figures, developed by the Bureau of Transportation Statistics, is a collection of charts and statistical tables about freight transportation in the United States. These interactive visualizations and tables provide a snapshot of freight movement; the extent, condition, and performance of the freight transportation system; the economic implications of freight movement; and the safety, energy, and environmental impacts of freight transportation.
Infrastructure Condition Evaluation (ICE) Tool
A tool that aids in the evaluation of the state’s Primary Highway System by using a composite rating calculated from seven different criteria – passenger, single-unit truck, and combination truck annual average daily traffic; congestion index value, International Roughness Index; PCI; and Bridge Condition Index. While each of these individual criteria indicates a different component, the collective offers the ability to evaluate the service and structural condition of roadway segments with a single composite rating.
