| Research Abstract |
The purpose of this study is to clarify the relationship of visibility and illuminance in residential areas. For this purpose, firstly the survey of illuminance and installation of street lighting situation is carried out, secondly the experiment on the visibility and illuminance was carried out. As a result, the following findings were obtained. (1)Even in a good living environment,the illuminance is below the lighting standard. (2)There are places with low illuminance and places with high illuminance, so the uniformity is not achieved in all areas.(3) Even more than the lighting standard, there aer places where visibility is not ensured. Based on these findings, we think that it is necessary to review the evaluation methods of street lighting and lighting standard including a review of the measurement technique.
