An Embedded Hardware-Software System to Detect and Foresee Road Ice Formation

This paper presents a reliable ice detection and forecasting system based on a special road weather information system and a data processing algorithm for ice event forecasting. The ice detection system is mainly based on two innovative sensors, developed ad hoc for this particular application; namely an ice sensor for the reliable detection of accumulation of ice or water on the sensor and a salinity sensor for the purpose of freezing point calculations. These data are then used by a statistical data processing algorithm or a neural network for ice event forecasting.
