Web2024 Design Hour Summaries: Peak, 30th and 50th Highest Hour . Design Hour Volume (DHV) is the hourly traffic volume used in the design of highways. The DHV is usually represented by the 30th highest hourly volume of the future year chosen for design. The following three graphs show the peak, 30th and 50th highest hour summary by hour, … 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. ...
WebThe Design Hourly Volume (DHV) is the standard for estimating the peak traffic loads during the day for design. The design elements such as street classification, design … WebJul 1, 2024 · design requirements for the project, this information is used by the Resident Engineer during construction to determine which clauses in the Standard Specifications apply to the project. DHV -- The two-way design hourly volume, vehicles. D -- The percentage of the DHV in the direction of heavier flow.
The calculation for the K factor is given by the formula DHV= K*AADT in which DHV is the "Design Hourly Volume," the 30th highest hourly traffic volume (in both directions) in the year in which data was collected, by vehicles per hour. WebThe DHV is based on the 30th highest hourly volume out of 365 counts (i.e., just over the 90% level). This essentially means that a road with a design based on this DHV will be able to handle traffic demand 90% of the time. DHV is determined by multiplying the ADT by the design hourly volume factor, also known as the K factor.
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.
