SURFACE project (2017-2020)
The goal of this project is to address the current deficiencies in European standard regarding (i) the definition and characterization of road surface photometry, (ii) traceable measurement and characterization methods for road surface characteristics and (iii) traceable reference data for photometric tables. The results will be used by CEN TC169/WG12 in the next revision of EN 13201 series, and by CIE TC4-50 in current CIE publications under revision.
Metrology Research Institute leads the WP3 on Prenormative guidelines and database.
Metrology Research Institute will contribute in providing procedures, requirements and data analysis methodologies for the measurement of the luminance or the reduced luminance coefficient considering aspects involved from sample selection to data analysis (such as aging of road surfaces, wet conditions, spectral properties etc.) in defining the parameters and quantities for the characterization of instruments, for their calibration and traceability and in producing pre-normative guidelines. The aim is that the guideline will be discussed during CIE TC4-50 meetings, and summarized in at least one ISO TC274 and CEN TC169 plenary meetings.
Identification of available database
Metrology Research Institute with Cerema and Metrosert will research and evaluate existing available data for r-tables, using data in technical and scientific publications.
Metrology Research Institute will contribute in writing a report on photometric quantities for road surface materials to support EN 13201 reference tables. The report will describe new or updated standard r-table considering a wide spread of road surface types. Data will be included from ad hoc measurements or from measurements carried out previously by partners (at least by Cerema) and at least by one stakeholder (selected by the stakeholders committee) in current standard geometries. This activity will help with the revision of EN 13201.
