Webhighway is not based on ADT, but on an hourly traffic volume instead. AASHTO and other organizations have determined that the 30th highest hourly volume (30 HV) of the year usually provides the most appropriate design for highways. The design hourly volume (DHV) is used by DOTD as the basis for design and is normally the projected 30 WebDirectional Design Hour Volume (DDHV) - The traffic volume expected to use a highway segment during the design hour of the design year in the peak direction.

Alberta's highway system is investigated and the users' perspective is considered by classifying the road sites into several types according to trip characteristics, such as trip purpose and trip length distribution. The main conclusions of the study are as follows ... Web30 th Highest Hourly Volume. It has been observed that 30 th highest hourly volume gives a satisfactory results in terms of performance & it is economical in nature. 30 th highest hourly volume is exceeded only 29 times in a years & all other traffic data will lie lesser than that. IRC consider this traffic volume as Design Hourly Volume. fishermen fishing
