To assess state–of–practice and identify lessons learned from experience, a literature search was conducted. The following lessons highlighted experience from a deployment in Minnesota where a real-time travel time information system was implemented to improve travel during roadway improvements on a 70 mile section of I-35 from Hinckley to Duluth, Minnesota. Using commercial off the shelf (COTS) software (TrafAlert™), MnDOT posted travel times on eight dynamic message signs (DMS), and a website with an online map. The following lessons were gathered from MnDOT staff and partners at the conclusion of the project in 2012.
