The Transportation Data Research Laboratory (TDRL), located in Duluth, Minnesota, is a part of the Northland Advanced Transportation Systems Research Laboratories (NATSRL) sponsored by the Minnesota Department of Transportation (Mn/DOT), University of Minnesota Duluth Science and Engineering, and University of Minnesota Center for Transportation Studies (CTS) and ITS Institute. TDRL's research focuses on all issues related to dealing with large scaled transportation data, which include efficient archival strategies, data processing algorithms for large-scaled ITS data, data quality management, efficient sharing of data, secure storage management, and developments of visualization and performance analysis tools. TDRL manages a Data Center that collects and houses Mn/DOT's state-level ITS transportation data, and provides on line data resources to Mn/DOT and public.
