Annual Adjustment Factors
The table in the Annual Adjustment Factors report shows the annual average percent change in traffic volumes from year to year by functional classification.
Caution should be used when applying the percentages in this table. Changes in traffic volumes at site specific locations can vary greatly from the volumes used to produce the averages, depending on the changes in land use and site specific traffic generators.
The factors should be used with judgment when atypical traffic patterns are encountered, such as volumes near major generators such as recreational areas, theme parks, shopping centers, football and baseball stadiums, etc.
