We have completed a system that can evaluate light distribution in real time as you view the screen, using computerized vehicle simulation graphic analysis of the light distribution pattern of headlamp used in automobiles. The system is able to generate a composite evaluation using the practical application of multi-fuzzy inference forms that include peripheral field of vision, calculating the unevenness of the light distribution on the road surface as well as the luminous flux (both emitted and reflected back) that illuminates the road, sidewalk and wall, at the same time evaluating the quantified data of disability glare, discomfort glare and contrast in relation to the visibility of the target (pedestrian, road delineation lines, fallen objects on the road) and adding glare from an oncoming vehicle and background brightness (of the sky, road surface, wall).
