Minnesota DOT deployed a dynamic late merge system for $900 per day per direction.
September 12, 2005
Minnesota,United States
Summary Information
Minnesota Department of Transportation's (Mn/DOT’s) Construction Office and Traffic Office developed a specification for a DLMS and worked closely with the vendor capable of providing the system. Mn/DOT reviewed other state DOT's (e.g., Michigan, Kansas, and Maryland) experience with dynamic merge technologies to determine the proper strategy for Mn/DOT work zones. The system Mn/DOT deployed provided guidance to motorists on proper lane usage via portable changeable message signs (PCMS). When congestion level was reached, the PCMS were activated. When traffic returned to free-flow the PCMS returned to “dark mode.” The costs provided were based on four DLMS study locations: three in urban settings and one in a rural location. The cost of detection was approximately $300 per day and three PCMS cost $600 per day for a total cost of $900 per day per direction.
For the 2005 construction season, Mn/DOT will include DLMS as a pay item in construction projects and require vendors to be on a Qualified Product List (QPL).
