Hydroplaning Potential in Coastal Regions

Hydroplaning is a critical pavement safety concern that occurs when a layer of water builds up between the vehicle's tires and the pavement surface, leading to a loss of traction and vehicle control. It is a significant contributor to wet-weather crashes and thereby poses a serious challenge to highway safety, especially for coastal regions where rainfall is more abundant and more frequent. Hydroplaning risk assessment fundamentally depends on the integration of multiple diverse datasets that reflect the interaction among crash occurrences, pavement conditions, and vehicle dynamics. These data items are typically recorded in different datasets maintained by various owners or agencies, each with their unique collection methods and standards. 

This research will develop data-driven likelihood models based on a verification check of the reliability of the important data variables, and a fusion of the available history data from diverse data sources to assess hydroplaning risks for coastal highways. The proposed research will also develop recommendations to be considered for roadway design and construction in association with wet-weather accident reduction procedures for transportation agencies.
