Heavy Commercial Annual Average Daily Traffic Count Locations, Minnesota

HCAADT is the theoretical estimate of the total number of heavy commercial vehicles using a specific segment of roadway (in both directions) on any given day of the year. This estimate represents the total number of heavy commercial vehicles per year divided by 365 and is developed using factors to adjust for season on sampled road systems in a particular given year. This information is displayed using the approximate collection site for each unique estimation.<br/><br/>Notice: Starting with the 2017 dataset, HCAADT no longer includes historical years as attribute fields within the GIS files. Instead, the last 30 years of available historical HCAADT data are provided in a zipped Access database. These changes were made to automate and accelerate the annual distribution of HCAADT data products.
