Advanced Pedestrian Control System (OTT case 08-007)
Summary - The Advanced Pedestrian Control System (APCS) guides a visually impaired person across an intersection. The person carries an Advanced Pedestrian Assistant (APA) unit or cell phone containing the APA software, which then initializes the intersection crossing station containing the Advanced Pedestrian Controller (APC). The APC in turn communicates with the traffic controller.
