ROAD ICING CONDITION PREDICTION FOR SHADED ROAD SEGMENTS

Title:

ROAD ICING CONDITION PREDICTION FOR SHADED ROAD SEGMENTS

Document Type and Number:

WIPO Patent Application WO/2021/203990

Kind Code:

A1

Abstract:

Road condition prediction for potentially hazardous road segments is described. For roadways that may contain accumulated frozen precipitation, a road segment for road condition prediction is selected based on weather conditions. Various models including a solar radiation budget model, a permanent structures model, a dynamic structures model, and a road condition model are generated for the selected road segment and account for shading effects on the road segment caused by objects near the road segment. A road condition prediction for hazardous conditions on the road segment is determined based on the road condition model and provided to a driver to alert the driver of any potentially hazardous conditions.
