# Exhibit 2

– Vehicle Classification Counts

Weekday vehicle classification counts from GDOT were obtained for the years 2008 through 2010 for the

entire state of Georgia. The counts were stratified by two areas, the counts within the 13

‐ county

portion of the Atlanta MPO area, and the remaining statewide counts. In order to provide a reasonable

sample, the remaining statewide counts were used to factor the outer 7

‐ county portion of the

nonattainment area. The vehicle classification counts collected were stratified based on the FHWA

vehicle classifications. The counts were then summarized into the 6 HPMS vehicle type categories. This

result was then summarized for the three years. The percent by vehicle type by road type based on

functional classification was calculated. The counts by the area type (urban versus rural) were combined

since FHWA eliminated the urban/rural area type distinction from HPMS functional classifications

beginning with the 2009 data, reported in 2010 1



# .

Table 1, below, lists the counts by year for the 13

‐ county area. Table 2 lists the final factors which were

applied to the 13

‐ county area VMT by vehicle type by road type based on the counts. Table 3 lists the

counts by year for the 7

‐ county area. Table 4 lists the final factors which were applied to the 7

‐ county

area VMT by vehicle type by road type based on the counts. These values were used to weight the VMT

from the travel demand model by road type by vehicle type for input into AADVMT worksheet importer.
