Snow Accumulation and Road Algorithm
Description
Generates hourly forecasts of road conditions across the network for a 3-day horizon. By processing atmospheric inputs from numerical weather prediction (NWP) models - including precipitation, wind, radiation, and dew point - it derives specific road-level variables such as surface temperature and snow or water accumulation. These factors are then integrated to determine the final traffic impact level, providing a precise assessment of how weather will translate into operational road disruption.
