The present invention relates to an in-ground traffic light, which comprises: a plurality of light emitting blocks installed on the bottom surface of a road on both entrances of a crosswalk in a transverse direction to be in contact with each other, and interlocked with walking and stop signals of a pedestrian traffic light to emit red and green light upward; a sound block installed in contact with the light emitting blocks, and interlocked with walking and stop signals of the pedestrian traffic light to sound an alarm sound during the walking signal; and a control unit controlling operation of the light emitting blocks and the sound block. According to the present invention, a pedestrian can clearly recognize a voice guide signal regardless of surrounding noise and a distance from the voice guide speaker.
