Road Weather Messaging on Dynamic Message Signs (DMS)

Part 2 of 2: Nearly 300 DMS are deployed across the state and are used for displaying real-time information to warn motorists of incidents, roadwork or congestion downstream that may be a potential safety hazard or may cause delays. When it comes to weather related messages, MnDOT has limited DMS usage to blizzard warnings or unexpected/isolated conditions that make catch a motorist by surprise. Concerns over displaying weather related messages on DMS are the timeliness of these messages and the potential overuse of these messages. If weather related messages could be tied to National Weather Service reports, Maintenance Decision Support System (MDSS) data and/or roadside weather sensors the messages could be more timely and accurate. Thresholds based on weather data could also be established so there are only particular situations where a weather related message is displayed rather than leaving it up to the discretion of an operator on-duty. This would improve customer trust in the message being displayed and reduce erroneous or over used messages.
