Abstract:
A process for producing an early warning signal of slick road conditions in a system for early warning of slick road conditions that includes at least one measuring station with probes arranged at at least one measuring point of a road system to be monitored, the process comprising:virtually creating at least one virtual station, which is defined at at least one other point in the road system to be monitored that is different from the at least one measuring point, the virtual station being assigned location specific parameters related to the at least one other point and meteorological data related to the at least one other point;calculating values indicative of slickness of the road surface at the at least one other point based upon the location specific parameters and the meteorological data related to the at least one other point; andproducing an early warning signal of slick conditions at the at least one other point based upon the calculated values.
