Homologation Specifications for Road Stations in Winter-Maintenance Decision Support Systems
Homologation is the certification of a product or specification to indicate that it meets regulatory standards. In these specifications, the name "winter-maintenance decision support system" (WMDSS) means any automatic data-acquisition system incorporating sensors installed both in the air near the roadway, and on or in the pavement in travel lanes. WMDSS homologation applies only to the atmospheric sensors and road sensors of road stations, and to their measuring chains and displaying devices. The homologation procedure consists of three successive stages corresponding to three distinct subfields: technical documentation for the user, enabling optimal operation of the station, station and sensor maintenance in a conventional road environment, and nature and quality of information provided by the various sensors. Homologation can be granted only at the conclusion of the third stage. Homologation is granted on the basis of the results obtained in a series of measurements (grouped by test) performed on production-line materials. The results, obtained exclusively from conventional laboratory tests, are compared with established thresholds.
