Title (EN) METHOD AND ARRANGEMENT FOR DETERMINING A CONDITION OF A ROAD SURFACE
(FR) PROCÉDÉ ET AGENCEMENT POUR DÉTERMINER UN ÉTAT D'UNE SURFACE DE ROULEMENT
Abstract:
(EN) The invention relates to a method for determining a classification of a condition of a road surface (3) for vehicle (1) traffic, said method comprising: determining a road surface condition associated with a road surface (3); and providing image data related to said road surface (3). Furthermore, the method comprises: determining said road surface condition in a predetermined measuring spot (5) along said road surface (3); identifying a plurality of road area sections (11, 12, 13, 14, 15) as regarded across the road surface (3), by means of said image data; and combining data related to said road surface condition and said road area sections (11, 12, 13, 14, 15) in order to determine a classification of a condition of the road surface (3) in at least two of said road area sections (11, 12, 13, 14, 15). The invention also relates to an arrangement for determining a classification of a condition of a road surface (3) for vehicle (1) traffic.
(FR) L'invention concerne un procédé de détermination d'une classification d'un état d'une surface de roulement (3) pour un trafic de véhicules (1), ledit procédé consistant à : déterminer un état de surface de roulement associé à une surface de roulement (3) ; et fournir des données d'image associées à ladite surface de roulement (3). Le procédé consiste en outre à : déterminer ledit état de surface de roulement dans un point de mesure (5) prédéfini le long de ladite surface de prédéterminé (3) ; identifier une pluralité de sections de zone de route (11, 12, 13, 14, 15) telles que considérées à travers la surface de roulement (3), au moyen desdites données d'image ; et combiner des données associées audit état de surface de roulement et auxdites sections de zone de route (11, 12, 13, 14, 15) afin de déterminer une classification d'un état de la surface de roulement (3) dans au moins deux desdites sections de zone de route (11, 12, 13, 14, 15). L'invention concerne également un agencement permettant de déterminer une classification d'un état d'une surface de roulement (3) pour un trafic de véhicules (1).
