Title: Annual Average Daily Traffic Segments in Minnesota

Abstract: AADT represents current (most recent) Annual Average Daily Traffic on sampled road systems. This information is displayed using the SDW_INCDT.TRAFFIC_SEGMENTS_ACTIVE feature class as of the annual HPMS freeze in January. Historical AADT is found in another table. Please note that updates to this dataset are on an annual basis, therefore the data may not match ground conditions or may not be available for new roadways.

The AADT_HISTORY_SAMPLED is not in the Commons yet. Please contact Christy Prentice to get a copy of the AADT_HISTORY_SAMPLED.

Purpose: Determine general estimates of segment specific, annual average daily traffic (AADT) on various route systems to meet FHWA annual reporting and assist in the annual allocation of state aid to local government for roadway maintenance and construction. Counts are taken on portions of the system each year so complete coverage for a given jurisdiction is generally accomplished on a two or four or 12 year cycle. More information about the Traffic Volume Program can be found at: www.dot.state.mn.us/traffic/data/
