Karl Peglau, a traffic psychologist and engineer, was tasked with designing new pedestrian signals to reduce accidents in an increasingly congested and complex city. Peglau observed that traditional traffic lights were insufficiently clear, especially for children, the elderly, and the visually impaired.
