Traffic Operations

Mn/DOT began its freeway traffic management efforts in the early 1970's. With deployment of those efforts, Mn/DOT saw a need for a central control facility and the Traffic Management Center was built in 1972 in downtown Minneapolis. As congestion increased in the Twin Cities, so did the need for new technologies and partnerships.

The Traffic Operations unit is responsible for managing traffic on the Twin Cities metro freeways with the use of ramp meters, variable message signs, lane control signals and loop detectors. The results are improved incident management and traveler information. Traffic Operations staffs the Operation Center Monday through Friday from 5:30 a.m. to 8:30 p.m., Saturday from 11 a.m. to 7 p.m., and on Sunday from 10 a.m. to 6 p.m. They monitor traffic conditions, assist in incident management and provide traveler information.

Traffic Operations staff also continually perform systems analysis of field equipment, the ramp meter algorithm and Operations Center equipment. They also analyze and research traffic flow trends, new technologies and other issues that affect congestion.

Mn/DOT's goal is to provide motorists with a faster, safer trip on metro-area freeways. Cutting-edge technology, progressive programs, partnerships and information delivery systems are key elements of its comprehensive services.

Mn/DOT Metro District's Signal Operations

The Mn/DOT Metro District's Signal Operations unit is responsible for the construction, inspection, operation, and timing of the traffic signals on the trunk highway system within the Twin Cities metropolitan area. The Signal Operations unit operates 635 signal (2002 data), most of which are owned by the State of Minnesota.

Signal Operations staff provide support to the Construction unit by providing quality control and inspection, coordinating signal turn-ons and coordinating activities between signal operations, Electrical Services Section and contractors. The Signal Operations staff is responsible for the timing and operation of all traffic signals. This involves developing timing and coordination of plans, responding to customer complaints and inquiries, monitoring system performance and detecting operational and maintenance problems.

The Signal Operations unit also assists other units in signal related training and in developing techniques and procedures in signal operations and construction.
