In this study, visibility of objects on the road is tested using image processing techniques over the photo of an illuminated road. Visibility level standard of the international commission on illumination was used was for this test. Through software developed for this purpose, a correlation was established between the qualitative values of pixels and photometric units over the road photo using image processing techniques. Thanks to the correlation found, it has become possible to calculate glare values of the road and the critical object over the road. Moreover, required parameters for the visibility level are entered into the developed software, making it possible to calculate the visibility of the critical object over the road.
Key words: Road lighting, luminance, visibility level, image processing.
