Steps are common features in our day-to-day living and working environment. Unfortunately, the occurrence of accidents on or around steps is thus inevitable. A failed visibility to see or recognize a step remains the most common attribute in these accidents. In this research, sensory scales of step visibility were created in order to examine the effects of five lighting conditions (D65 fluorescent lamp, circular-shape fluorescent lamp, LED lamp, halogen lamp, and the mixture of these lamps) on step visibility in sensory testing methods. Results of sensory tests revealed strong correlation within lighting conditions on step visibility. Influence of visual characteristics of each step was also examined and clarified.
