Model System Engineering Documents for Six Intelligent Transportation System (ITS) Applications
MnDOT completed systems engineering documents for six ITS applications (dynamic message signs, video, traffic detection, communications and radio, flood warning, and ramp metering) for use in future project planning and implementation to ensure compliance of 23 CFR 940 and to address Connected and Automated Vehicle (CAV) readiness for Minnesota.
Intelligent Roadway Information System (IRIS) Open Source Advanced Transportation Management System (ATMS) Software Implementation
MnDOT developed IRIS (open source ATMS) with in-house staff in the late 1990s. Other agencies were also able to utilize and implement IRIS (e.g., Wyoming, Nebraska, Indiana, Caltrans, Chandler AZ, Bloomington MN, Scott County MN, and the Mall of America in Bloomington, MN).
