Steps

  1. Use InfoPave's 'Data Selection and Download' tool to browse tables organized under Structure, Climate, Traffic, and Performance categories
  2. For integrated, ready-to-use extracts, use one of the four Analysis Ready Datasets (ARMAD materials, ARCLD climate, ARTRD traffic, ARPED performance) instead of raw tables
  3. For a full data dump, request the Standard Data Release (Access-database format) via InfoPave or the LTPP Customer Support Service Center (ltppinfo@dot.gov)
  4. Cross-reference the LTPP IMS User Guide (PDF, in the InfoPave Repository) for table/field definitions
