• Description:
  To provide a better understanding of how short-duration truck volume counts can be used to accurately estimate the key variables needed for design, planning, and operational analyses, the Long-Term Pavement Performance (LTPP) program recently completed a study entitled "Vehicle Volume Distributions by Classification" (FHWA-PL-97-025, June 1997). This TechBrief presents key findings from the study. In summary, it was found that truck volumes vary considerably by time of day, day of week, season, and from location to location. States need to develop mechanisms that can adjust short-duration truck volume counts to account for these changes. These mechanisms must be sensitive to differences in the amount of through-truck traffic on specific roads, as well as differences in trucking patterns that occur as economic activity changes from one region to another.
