Based on accounting data on stationary permanent traffic volume, AADT is calculated applying the formula (Leduc 2008; Transport and Road Research.

The researchers calculated the annual average daily traffic (AADT) for each site and year as the average of the AADTs of the segments within each site-year.
For each participant's residence, we calculated traffic density by summing the vehicle kilometers of travel (VKT) within a 300-m radius buffer by multiplying the AADT by the length of the road segment for each road segment with AADT values within the buffer, then dividing by the buffered area (0.
The AADT data was collected from the Department of Transportation, Commonwealth of Virginia.
