METRICA, l’archivio istituzionale della produzione scientifica dell’Istituto Nazionale di Ricerca Metrologica, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ente.
METRICA utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishThe reflection characteristics of the road surfaces play a key role in the design of road lighting installations, when the average luminance is the target quantity standards specify to assure the required safety conditions of the road traffic. The measurement of the reflection characteristics of the road surface can be done in laboratory, using road samples, or on-site using peculiar instruments. This paper describes a simple technique for on-site characterization of a road surface. In its simplest formulation this technique requires only a matrix luminance meter, i.e. an imaging luminance measuring device (ILMD) and a calibrated white or grey reference flat surface. In this case the SI calibration of the luminance meter is not required.

| Abstract: | The reflection characteristics of the road surfaces play a key role in the design of road lightin...g installations, when the average luminance is the target quantity standards specify to assure the required safety conditions of the road traffic. The measurement of the reflection characteristics of the road surface can be done in laboratory, using road samples, or on-site using peculiar instruments. This paper describes a simple technique for on-site characterization of a road surface. In its simplest formulation this technique requires only a matrix luminance meter, i.e. an imaging luminance measuring device (ILMD) and a calibrated white or grey reference flat surface. In this case the SI calibration of the luminance meter is not required. | |
