This dataset contains data on truck movements by tonnage, value and truck units for select commodities and corridors analyzed in USDA's, "The Importance of Highways to U.S Agriculture" report.

This map shows the truck volumes moved along select corridors in millions of tons. By default the map shows total tonnage and displays all 17 corridors. Use the filters on the right to select alternate commodities or corridors

This map shows truck movements in millions of dollars along select corridors. By default the map shows total value and displays all seventeen corridors. Use the filters on the right to select alternate commodities or corridors.

This chart shows the average annual daily traffic for select corridors on a daily basis, expressed in thousands of miles. Use the filters on the right to choose a particular corridor name, highway segment or corridor number. Click anywhere on the bar to see different highway segments for a particular corridor.

This chart shows the travel time index (TTI), a ratio of peak congestion to free flow traffic where 1 is free flow traffic during peak congestion, and a higher value indicates longer travel times. For example, a TTI of 1.2 indicates that travel time during peak congestion would take about 25% longer than in free flow traffic. Use the filters on the right to choose a particular corridor name, highway segment or TTI. Click anywhere on the bar to see different highway segments for a particular corridor.

This map shows the truck volumes moved along select corridors in thousands of truck units. By default the map shows total truck units and displays all 17 corridors. Use the filters on the right to select alternate commodities or corridors.

This chart shows the reliability of travel times for trucks on select segments and corridors, that is how consistent congestion levels are over time. Use the filters on the right to choose a corridor name, highway segment or TTTR. The default TTTR is set above 2 to show the least reliable segments. Click anywhere on the bar to see different highway segments for a particular corridor.

This chart shows the number and percentage of pavements in good, fair or poor condition for select corridors. Use the filters on the right to choose a particular highway segment and urban/rural designation.

This chart shows the number and percentage of bridges in good, fair or poor condition for select corridors. Bridges rated 7 or more are classified as good, bridges with rating of 5 or 6 are classified as fair while bridges which have a rating of 4 or less are classified as poor. Use the filters on the right to choose a particular highway segment.
