This dataset contains data on selected annual performance characteristics for the study corridors in the Importance of Highways to U.S. Agriculture Report. The dataset includes through lanes, annual average daily traffic (AADT), pavement condition, functional class of vehicles, National Highway System (NHS) designation, urban /rural designation, route number and corridor segment identification. The Volpe Center derived this study specific dataset from the Federal Highway Administration's (FHWA’s) Highway Performance Monitoring System (HPMS) data.
