Design hourly volume dhv
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. 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 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. WebDesign Hourly Volume (DHV) The DHV is the one-hour volume selected from the design year to determine the highway design. 5. Peak-Hour Traffic The peak-hour traffic is the highest number of vehicles found to be passing over a section of highway during 60 minutes. 6. Peak-Hour Factor (PHF) The PHF is a ratio of the total hourly volume occurring ...
