WebPHF = Hourly volume/Peak rate of flow (within the hour) If 15-min periods are used, the PHF may be computed as PHF = V/ (4 x V15) Where PHF = peak-hour factor, V = hourly volume (vph), and V15 = volume during the peak 15 min of the peak hour (veh/15 min). WebThe specific characteristic curve recommends that it might be uneconomical to choose the design hourly volume, which is higher than a value which will be exceeded during the 29 hours in a year. Therefore, value of 30 th maximum hourly volume is commonly chosen as design hourly volume.
