Istanbul Technical University (ITU) and Istanbul Transportation Communication and Security Technologies Inc. (ISBAK), developing a common project, with the support of Ministry of Science Industry and Technology, established a test road in Istanbul, ITU Ayazaga Campus where different road conditions and scenarios can be practiced in order to assess and measure the visual performance of drivers. According to the measurements and experimental results which will be held on the test road, it is aimed to develop a "road lighting automation system" working with correct dimming scenarios. On the test road, visibility measurements are done using objects with 0.20, 0.30, 0.40 and 0.50 reflectance factors, under different lighting conditions such as; M2, M3, M4 and M5 lighting classes and for 4000K and 6000K colour temperatures. 320 measurement photographs taken with camera luminancemeter are examined to determine object and background luminances. 1920 object luminance and background luminance values are determined from the photographs. Visibility levels on all measurement points for all scenarios are calculated. In this paper, the results of measurements and calculations are analyzed and it is attempted to establish the basis for the visibility performance in automation scenarios.
