This study investigates recognition and detection abilities of nighttime pedestrians by observers and using a photographic method. The examination of the visibility of nighttime pedestrians is done and afterwards evaluated by two methods. In the first method observers were asked to detect a pedestrian from a slowly moving vehicle. In each attempt, detection distance was recorded. From the place of detection, a digital photography was taken from the still vehicle. Analysis of the digital photography in computer graphic software is the keystone of the second method. The article also shows potential effect of retroreflector positioning on recognition of nighttime pedestrians.
