OPTIMIZATION OF ROAD SURFACE REFLECTIONS PROPERTIES AND LIGHTING: LEARNING OF A THREE-YEAR EXPERIMENT

摘要

Adapting light distributions of luminaires to different types of road surfaces when new and also along their lifetime remains a challenge. In this paper, we present the assessment, over its first three years, of an innovative compared to a conventional infrastructure renovation. The innovative solution, called Lumiroute, integrates both a light road surface and LED lighting that can be tuned to follow the evolution of the road surface photometry. Regular on-site evaluation of the conventional and photometric characteristics of the pavements and the luminance perceived by the driver over time were performed. This paper presents the outcome of this experiment, in terms of photometry, energy consumption, obtrusive light and financial aspects of the project.
