APPARATUS AND METHOD FOR CONTROLLING GUIDE BROADCASTING SOUND VOLUME IN PEDESTRIAN CROSSING

摘要

The present invention comprises: a pedestrian information detection unit for detecting pedestrian information on a pedestrian who is waiting for a traffic signal in a pedestrian crossing; a sound volume measurement unit for measuring a sound volume of noise around the pedestrian crossing; a guide broadcasting output unit for outputting guide broadcasting to the pedestrian; and a broadcasting sound volume determination unit for determining a sound volume of the guide broadcasting on the basis of the pedestrian information extracted by the pedestrian information detection unit and the sound volume of the noise around the pedestrian crossing, which is measured by the sound volume measurement unit, and causing the guide broadcasting output unit to output the guide broadcasting having the determined sound volume.
