WebA K factor is the ratio between a peak hour and the ADT. This can be many different factors. The most common is typically referred to as the K-30. It is specifically the ratio between the 30th highest hour and the AADT. When looking at a graph of the highest hour volumes at a counting station, those at the WebThe peak 15 minute volume is 135 pcu in this case. The peak hour factor (PHF) is found by dividing the peak hour volume by four times the peak 15 minute volume. PHF = 464 / (4 * 135) = 0.86. The actual (design) flow rate can be calculated by dividing the peak hour volume by the PHF, 464/0.86 = 540 pcu/hr, or by multiplying the peak 15 minute ... locker boot mats https://fsanhueza.com
