How to do a manual traffic count
A Highway Capacity Manual (HCM) analysis therefore applies a peak hour factor (PHF) to convert the maximum min volume into an hourly flow rate. The PHF is found by dividing the peak hour volume by the product of 4 times the peak min volume. PHF = peak hour volume 4 × highest 15 - min volume.
