Abstract

Visibility evaluation experiments were conducted on reflective wristbands in five colors for two groups: a young age group and an elderly-simulated group. Reflective materials were worn on the wrist, ankle, and wrist + ankle, and 150 samples were used at 10m intervals at distances ranging from 10m to 100m on a sidewalk at night. Although there were differences depending on the distance, the reflector visibility evaluation of the young age group was significantly higher than that of the elderly-simulated group in all three wearing positions of the five reflective material colors ‹ p < 0.05 ›. Yellow had a visibility rating of 3.5 ‹ between " barely visible " and " somewhat visible " › or better at 40m of low-beam illumination for both groups. In addition, both groups had the lowest visibility ratings when the reflective material was worn on the wrist.
