Annual average daily traffic (AADT) is one of several statistics that transportation agencies use to report roadway volumes. However, high traffic volumes are often concentrated over short and specific time periods due to seasonal activities, such as tourism, vacation, or holiday-related travel. To understand and address seasonal traffic volume fluctuations without excessive investment, an additional measure to aid in traffic volume analysis beyond AADT can add value to the prioritization process. The underlying premise is that a reliance on AADT only may overlook strategically important routes with heavy seasonal traffic loads (but low average volumes) in the prioritization process. This paper presents a methodology for the development of peak average daily traffic (PADT) factors for potential use in strategic prioritization efforts. The goal is to explore whether PADT may be suitable to supplement or replace conventional AADT in the prioritization process since PADT may more accurately represent seasonal peak loads on some facilities.
