Crossing problems that may be ameliorated by APS. Survey of blind pedestrians and orientation and mobility specialists. In 1998, the American Council of the Blind (ACB) and the Association for Education and Rehabilitation of the Blind and Visually Impaired (AER) conducted surveys having similar questions to determine problems experienced by blind pedestrians during street crossings.
