An Educational Video Improves Pedestrians’ Appreciation of Nighttime Visibility Issues (Extended Abstract)

Most pedestrian fatalities occur at night, primarily due to limited visibility. The strategic use of retroreflective materials, particularly positioned to highlight biological motion, significantly enhances pedestrian conspicuity. However, typical pedestrians underestimate these benefits and overestimate their own conspicuity to oncoming drivers at night. This study evaluated the efficacy of a video designed to correct these misconceptions. Fifty-four undergraduates were randomly assigned to watch the video or not. Participants estimated the distance at which an approaching driver could recognize a pedestrian wearing five different clothing configurations, rated each configuration’s visibility and safety, then completed a comprehension test. Participants who watched the video demonstrated a better appreciation of the conspicuity advantages of retroreflective configurations and the limitations of fluorescent or non-reflective clothing. Overall, results strongly support the utility of a brief, video-based educational intervention to educate pedestrians about critical concepts for accurately assessing and improving their own nighttime visibility.
