Icy Road Forecast and Alert (IcyRoad): Validation and Refinement Using MDT RWIS Data

State Departments of Transportation (DOTs) need road ice condition forecasts to enhance public safety and awareness. This research was divided into two areas, Task 1 Development of IcyRoad Model and Task 2 Validation of the Ice Formula. Task 1 - A statewide IcyRoad model has been developed, tested, and refined during winter 2020-2021 using Montana Road Weather Information System (RWIS) measurements. The hourly road ice forecast accuracy improved from 62% to 82%. Task 2 -The formula does not appear to hold true with this dataset, but principal component analysis (PCA) of hyper-spectral data can identify, water, ice, and snow in comparison to dry asphalt.
