  • Patent number: 4165570
    Abstract: A method of and audio/visual apparatus for training and testing pedestrians, especially children, in the safe transit of roadways, intersections and crosswalks are disclosed. The apparatus comprises an automated system including a pair of image projectors arranged to project a sequence of images from two groups of images in generally confronting relation across a spacing defining a pedestrian passage. The images include scenes corresponding to roadway views as seen in opposite directions from a marginal edge of the roadway. Some of the images depict an unsafe crossing condition for a pedestrian, such as, for example, a roadway scene with a travelling motor vehicle. A signaling device generates an audible and/or visual signal whenever an image of an unsafe crossing condition appears on either screen.
