Title:
Precipitation and Road Surface Information. Is it Possible to Make a Road Weather Climatology with RWISS Data? A Prospective Study
Abstract:
Since a lot of Road Weather Information Systems (RWIS) are installed on the road network for winter maintenance, a lot of data on temperatures, precipitation, and the state of surface of the pavement are available. A capitalization and a centralization of these data could give information on pavement condition and it could be possible to make a road weather climatology. As a prospective study, the data of about 12 RWIS stations were studied for one year. After a presentation of the results of the statistical analysis, the limits of such an approach are presented. There is first a discussion on the reliability of the information given by the RWIS (concerning the storage of data, the importance of the software, the sensors performances), and then a discussion on the extrapolation of the sensor measurements to the pavement. Before combining large amounts of data, there is a need for more reliability and standardization of RWIS data.
