Design hourly volume dhv
WebLevels 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 counts at intersections … 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.

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. 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 conditionis not met (in the case of manual counts), a default value is applied. ...
