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
