Description
Summary:Taking into account the actual photometric characteristics of a road surface to design and then adjust a lighting installation is seldom done. In a lighting renovation, one of the Commission Internationale de l'Eclairage's standard r-tables is arbitrarily chosen although they are no longer representative of the characteristics of current road surfaces. The objective of the study is to assess an optimized, evolutive pavement and lighting combination, called Lumiroute®. To do this, two conventional designed sections were compared with two Lumiroute® sections. On-site measurements of road photometry, luminance and power consumption were conducted at regular intervals for three years. This paper presents the results of the photometric study together with an economic analysis. The Lumiroute® sections offer optimized performance and increased efficiency in comparison with the ordinary sections, particularly with regard to light and energy performance.
