Educational interventions successfully reduce pedestrians' overestimates of their own nighttime visibility.

Pedestrians dramatically overestimate their own visibility at night. This is likely to result in pedestrians unknowingly engaging in dangerous behavior. To determine the extent to which pedestrians' estimates of their own visibility are influenced by educational interventions, clothing reflectance, and headlamp beam setting, participants in 2 experiments estimated their own nighttime visibility by walking toward a stationary car to the point where they believed they were just recognizable as a pedestrian.
