| Abstract: | Using recent accident data to simulate a common collision environment, a 10‐minute car journey was filmed in which a moving or stationary pedestrian wearing one of two types of retroreflective clothing appeared in an environment with high visual clutter. It was hypothesized that moving pedestrians would be detected at greater distances when wearing retroreflective aids in biological motion configuration (‘biomotion’ clothing), but not when wearing a standard retroreflective vest. Participants viewed films of the journey, pressed a button when they detected the pedestrian and rated the difficulty of the task. Biomotion clothing did not significantly increase detection distance for either moving or stationary pedestrians compared to the vest. However, moving pedestrians were detected significantly further away than stationary pedestrians with both clothings. The results do not support the hypothesis that biological motion clothing affords recognition at greater distances than standard conspicuity aids in environments with high visual clutter.
