Sensor based adaption of treatment strategies

摘要

1. State of the art now-casting of both air and pavement surfacerntemperature are already feasible on the highway network in Austriarn2. Deviations from actual conditions can be reduced if the predictions arerncalibrated based on temperature profiles and sensor measurementsrn3. The quality of state of the art nowcasting of precipitation has improvedrnconsiderably and is of great value for winter maintenance decisionsrn4. Current prediction models still fall short as a solid base for the selectionrnof appropriate applicationnrates without real-time sensor measurementsrnand the observations from experienced winter maintenance personnelrn5. Model based automated recommendations for application rates seemrnfeasible on the highway network if the winter maintenance vehicles arernequipped with sensors for pavement temperature and film thickness.
