• Abstract:
  This study pursued five objectives. The first objective was the development of a study data base. Second, the study provided a general understanding of congestion. This understanding should include techniques for defining and measuring congestion as well as estimating its duration and extent on a national basis. Third, two specific products were developed by analyzing the data that were collected: (1) revised AADT/C vs V/C relationships and (2) temporal distributions of traffic. Fourth, the study revised the congestion term in the HPMS speed determination models previously developed for FHWA. Finally, the study outlined options for monitoring congestion on a continuing and national basis.
