Can enhancing color on dynamic message signs improve clarity and safety on the road? In a new MnDOT-funded project, researchers are studying how colors on dynamic message signs affect driver perception and information comprehension. A pilot study will help identify which color options improve visibility, reduce distraction, and support safer travel.

New Project: Can Enhancing Color on Dynamic Message Signs Improve Clarity and Safety? The majority of MnDOT’s dynamic message signs (DMS) are equipped to produce full color/full matrix messaging. Current signage regulations refer to retroreflective colors for static signs, but MnDOT…

When temperatures fall below 15°F, regular road salt loses effectiveness. To keep roads safe during extreme cold conditions, transportation agencies often use an alternative deicer to treat roads. In a completed LRRB-study, researchers evaluated the performance of alternative deicers on Minnesota roads. Results show that a mixture of salt brine and alternative deicer can help winter maintenance crews manage snow and ice when road salt alone is not enough.

Evaluating the Use of a Common Alternative Deicer When temperatures fall below 15 degrees Fahrenheit (F), salt loses its effectiveness at melting snow on roads. To accommodate lower temperatures, transportation agencies often combine an alternativ…
