Design hourly volume dhv

WebDesign Hour Volume. Levels of service are calculated using the design hourly volume (DHV). The DHV for intersections is the traffic flow that occurs during the peak traffic hour on an average day. Typically, traffic … WebThe traditional two-way design-hour volume (DHV) is multiplied with directional split to obtain the value of directional design-hour volume (DDHV) for multilane highways. This method, however, has limitations that have been revealed in previous studies.

WebV = hourly volume (vph), and V15 = volume during the peak 15 min of the peak hour (veh/15 min). Where the peak-hour factor is known, it may be used to convert a peak-hour volume to a peak rate of flow, as follows: v = V/PHF (2-3) Where v = rate of flow for a peak 15-min period (vph), V = peak-hour volume (vph), and PHF = peak-hour factor. WebOct 10, 2024 · The peak hour factor (PHF) is found by dividing the peak hour volume by four times the peak 15 minute volume. 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 volume by four, 4 * 135 = 540 pcu/hr.
