Directional … The calculation for the K factor is given by the formula DHV= K*AADT in which DHV is the "Design Hourly Volume," the 30th highest hourly traffic volume (in both directions) in the year in which data was collected, by vehicles per hour. WebDesign Hour Volume Factor, DHV (K) The K-factor represents the percentage of AADT during the design hour. It is calculated by dividing the peak hour volume by the AADT. A 24-hour count is required to calculate the K-factor. If this condition is not met (in the case of manual counts), a default value is applied. The high energy music 80\u0027s original
