PURPOSE: A walk signal lamp is provided to enable a pedestrian to cross a road with an easy attitude by displaying the remaining time of a walk signal as a number and a yellow signal. CONSTITUTION: A signal indication part(100) sequentially displays a green signal, a yellow signal, and a red signal. A counter(200) counts the lighting time of the green signal, the yellow signal, and the red signal. A control part(300) outputs a first, a second, and a third control signal. A driving part(400) lights the yellow signal, the red signal, and the green signal, respectively. A remaining time display part(120) digitally indicates the remaining time. A voice output part(500) outputs a pedestrian guide voice signal through a speaker. |
