Roadway Datatraffic on a highway

The Roadway Data unit provides a bounty of data such as roadlog files with information on location, jurisdiction, functional classification, surface/shoulder type, and width and reference points; control section records and construction project logs; and a trunk highway roadway history file that includes profiles of roadway cross sections. The unit also maintains the Transportation Information System database or TIS.


TIS is an integrated database with roadway and selected bridge, accident, traffic and pavement data. It is subject to ongoing revisions, which results in differences in the information presented on reports over time. To allow for consistency, the VMT and Mileage reports on this web page are based on a "snapshot" of the data which is taken during every mid-year. The data and statistics presented may also vary from the information obtained from other sources. For additional information about MnDOT traffic data, visit
