Kind Code:
A1
Abstract:
The present invention relates to floor traffic lights displaying signals by emitting light from floor surfaces on the edges of a crosswalk, the floor traffic lights comprising: a first signal display group in which one group of signals, displayed one column apart from each other and extending longitudinally among all floor traffic lights installed longitudinally along a boundary stone, displays the same color in response to a specific signal of a pedestrian traffic light; a second signal display group in which the remaining group of signals other than the one group of signals are not displayed in response to the specific signal of the pedestrian traffic light when the first signal display group is displayed; and a control unit for controlling the floor traffic lights in response to signals of the pedestrian traffic light, wherein, when the pedestrian traffic light is a green signal, the control unit causes only one of the first signal display group or the second signal display group to display and causes the other to not display, and when the pedestrian traffic light is a red signal, the control unit causes both the first signal display group and the second signal group to display. According to the present invention, not only non-colorblind people but also colorblind people are able to identify the signal display of the floor traffic light and thus easily use the signal.
