説明
Lighting for streets should be designed in such a way that pedestrians on the street at night are able to identify the general characteristics of “other” persons still some distance away on the road. The illuminance level to be provided has been investigated experimentally in the laboratory by utilizing a lighting simulator. In the experiments, observations were repeated by 3 observers, 10 times each, for 30 different lighting conditions. As a result, a value of 2 lux for the vertical illuminance on the “other” person's face has been obtained as the minimum value that allows pedestrians to identify “other” persons at a distance of 4 metres (whether he, `she is an acquaitance or a stranger).
