Title:

Development of an Expert System for Forecasting Frost on Bridges and Roadways in Iowa

Abstract:

An expert system has been developed that provides 20-hour forecasts of roadway and bridge frost for locations in Iowa. The system is based on analysis of frost observations taken by highway maintenance personnel, analysis of conditions leading to frost as obtained from meteorologists with experience in forecasting bridge and roadway frost, and from fundamental physical principles of frost processes. The expert system requires the forecaster to enter information on recent maximum and minimum temperatures and forecasts of maximun and minimum air temperatures, dew-point temperatures, precipitation, cloudiness, and wind speed.
