HIGHWAY, BRIDGE AND AIRPORT RUNWAY DETECTION SYSTEM PREDICTS FROST AND ICE CONDITIONS BEFORE THEY OCCUR

THE NEW HOLLEY ICE CONDITION DETECTOR SYSTEM THAT PREDICTS FROST AND ICE CONDITIONS BEFORE THEY ACTUALLY OCCUR ON BRIDGES, HIGHWAYS, AND AIRPORT RUNWAYS IS DISCUSSED. THE SYSTEM HAS BEEN USED SUCCESSFULLY BY THE MICHIGAN DEPARTMENT OF STATE HIGHWAYS ON THE FLINT RIVER BRIDGE. A SIMILAR DESIGN IS UNDER EVALUATION FOR USE ON AIRPORT RUNWAYS, AND A SYSTEM OF SNOW STORM PREDICTION IS CURRENTLY UNDER DEVELOPMENT. THE SYSTEM INCORPORATES HUMIDITY SENSING FOR ANTICIPATING FROST THAT LEADS TO ICE FORMATIONS, AND SEPARATE SENSORS FOR SENSING ICE FORMATIONS RESULTING FROM PRECIPITATION. WHEN THE SYSTEM DETECTS THE CONDITIONS THAT LEAD TO ICE FORMATION, A WARNING SYSTEM OR DEICING SYSTEM CAN BE AUTOMATICALLY INITIATED BEFORE FROST FORMS. WHEN THESE CONDITIONS DISAPPEAR, THE DETECTION SYSTEM AUTOMATICALLY SHUTS OFF THE WARNING OR DEICING SYSTEMS. APPLICATION OF DEICING CHEMICALS WILL DE-ENERGIZE THE SYSTEM. /SAE/
