Evaluation of Road Weather Messages on Dynamic Message Signs (DMS) Based on Roadside Pavement Sensors

Nearly 300 dynamic message signs (DMS) are deployed across the state and are used for displaying real-time information to warn motorists of incidents, roadwork or congestion downstream. 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. A current research project is working to integrate National Weather Service Warnings into MnDOT's IRIS software which is used to deploy messages on DMS throughout the state. That project will help MnDOT staff deploy blizzard warnings more efficiently than we currently do manually. Separate from that project, the RTMC is looking at deploying a system on Hwy 12 that would display weather-related messages on DMS for unexpected/isolated conditions based on roadside pavement sensors. This research project would evaluate the effectiveness of the system being deployed on Hwy 12 in changing driving behavior by measuring any reduction in speed or increase in following distance of vehicles after viewing the message.
