PURPOSE: A handrail for crossing prevention is provided to prevent traffic accidents by warning a person who is going to cross a road of a danger using a speaker. CONSTITUTION: A handrail for crossing prevention comprises posts(1100) and partition members(1200). Each post comprises a column member(1110), a weight detection sensor(1120), a control unit(1130), a speaker(1140), and a power supply unit(1150). The partition members are inserted into both surfaces of the column member. The weight detection sensor is installed on the top of the column member and senses the weight of a person. The control unit receives the sensed signal and sends an announcement signal to the speaker. The speaker receives the signal from the control unit and outputs a voice signal for crossing prevention to the outside. The power supply unit supplies power to the weight detection sensor, the control unit, and the speaker. |
