摘要：The presence of road lighting helps a car driver to identify nearby cars. The availability of road lighting can also reduce the occurrence of security disturbances however it has not been considered as the cause of accident. A study was conducted to analyze the visual perception of car drivers toward the road lighting. The research was conducted on Cikampek and Cipularang freeways which include straight and curved road sections. Data collection was conducted using questionnaires as the measurements instrument by asking the participants to watch the video footage of the freeway. The results show that the car drivers feel safer and more clarity in identifying the traffic signs and road marking in the presence of road lighting. Furthermore, yellowish road lighting provides more visual safety perception than white lighting which opposed with other previous studies. This result was obtained from the existing condition in the questionnaires without any control variable.
