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 http://www.mndot.gov/tda/.
Vehicle Miles Traveled (VMT) - multiple of centerline mileage and number of motorized vehicles that travel past a certain location during a specific period of time
(Centerline) Miles and Lane Mileage - miles per route and a multiple of continual driving lanes and mileage, organized by city, county, route system, surface type, and functional class
Construction Project Log - index of all past and present trunk highway construction projects, organized by county and control section
Trunk Highway Log Point - sequential listing of trunk highway landmarks one crosses when driving along the road in the increasing (reference post) direction
Major FHWA Categories - information regarding the three main ways to classify roadways: NHS, Functional Classification, and Federal Urban/Rural status; also includes data on the legislative and congressional district of each road segment
National Highway System (NHS) - roadways important to the nation's economy, defense, and mobility
Functional Classification - the process by which all roads are grouped into classes or systems according to the character of service they are intended to provide
Control Sections, Statutory Routes, and Memorial Routes - divided and designated segments of the state highway road system
