A system, device and associated methods are presented for use in providing onsite information to visually impaired persons. The system includes an announcement device and a personnel device. The announcement device is configured to be installed at an onsite location, such as at a traffic light and on a taxicab. The announcement device is configured to emit an identification signal in which it is preferable that the identification signal is continuously emitted. The personnel device is configured to detect the identification signal so that the personnel device is able to alert the visually impaired person that the announcement device is located nearby. The personnel device is also configured to allow the person to select and activate a desired feedback selection signal to transmit from the personnel device to the announcement device so that the announcement device can subsequently transmit back any number of different announcement signals such as direction signals, electronic signals, audio signals, and visual signals.
