Systems Engineering for Snow and Ice Control (SEASIC)

Project Description

The MnDOT Systems Engineering for Automated Snow and Ice Control (SEASIC) project produced model systems engineering documents, to be used by MnDOT Districts for future deployments of systems that provide traveler information and traffic control for weather events on interstates and state highways, particularly in “remote” areas. The following system types were included in the project:

Road Closure Systems:

  • System A - Road Closure System (with Gates) for Access Controlled Highways
  • System B - Road Closure System (with Gates) for Non-Access Controlled Highways
  • System C - Road Closure System (no Gates) for Non-Access Controlled Highways

Advisory Message Systems:

  • System D - Changeable Message Signs (CMS) for Advisory Messages
  • System E - Dynamic Advisory Messages for Recurring Hazardous Weather-Related Conditions

Project Benefits

The systems provide motorists with information regarding closures, road and weather conditions, construction and maintenance delays, and other conditions that could adversely impact safety and travel routes. The remotely operated and dynamic functions (if deployed) will assist MnDOT with efficiently managing road closure operations and providing advisory messages to the traveling public.
