Road Safety by Improved road lighting: road lighting measurements and analysis
This paper describes the fundamentals of the image-resolved luminance and color measurement technique. Its aims and solutions are presented. The determination of image-resolved luminance and color measurements is the state-of-the-art in many applications, e.g. for road or street lighting. In today’s devices, luminance and color measuring cameras are attached to high-quality Charge Coupled Devic...
متن کاملRoad lighting and headlights: Luminance measurements and automobile lighting simulations
This paper focuses on lighting dimensioning and lighting quality of traffic lighting. The work considers the factors that are important in creating optimal lighting conditions and luminous environment for night-time driving. The work is based on simulating, measuring and analyzing traffic lighting. The work introduces a new method for road luminance measurements and analysis. For simulation of ...
متن کاملMetrology of Road Surface for Smart Lighting
The knowledge of the luminance coefficient q or of the reduced luminance coefficient r of road surface is an unavoidable requirement for designing road lighting installations able to assure adequate road luminance for visual conditions, energy consumption and traffic safety according to standard requirements. Unfortunately q available data refers to measurements made during the seventies with n...

The introduction is followed by a review of trends, directions, and problems in current road lighting research and practice. The following part of the work introduces an advanced approach to road lighting mea...
متن کاملAir pollution in road tunnels.
As a part of a study of pollution of the air by motor vehicles, measurements have been made in two London road tunnels during periods of high traffic density. The concentrations of smoke and polycyclic hydrocarbons found there are much higher than the average values in Central London, but they are of the same order of magnitude as those occurring during temperature inversions on winter evenings...
