[

At this time, the controller 161 detects a pedestrian crossing the pedestrian crossing 11 at the time of the gait signal through the pedestrian detection and stop line display driver 166. When the pedestrian is not crossing the pedestrian crossing 11, 20 is switched to green or the like and the pedestrian signal lamp 11 is switched to green through the pedestrian signal light sensor 100, And controls the lamp module 134 of the bollard 130 and the lamp module 144 of the safety fence 140 so as to maintain the red light, And the red light of the stop line indicator 150 can be maintained to be safely traversed.

If the pedestrian senses that the pedestrian has crossed the pedestrian 11 from the pedestrian detection and stop line indicator 150 through the pedestrian detection and stop line display driver 166, The shutoff bar 112 is lowered by controlling the breaker 110 through the breaker driving part 164 so as to isolate the crosswalk 11 so that the crosswalk 11 is isolated.

The control unit 161 controls the lamp module 134 of the bollard 130 through the bollard driving unit 165 so that the green lamp is turned on and the lamp unit of the safety fence 140 is operated through the safety fence driving unit 166 And the lamp module 152 of the pedestrian detection and stop line indicator 150 is illuminated in green through the pedestrian detection and stop line display drive unit 167 so that the vehicle on the road 12 travels, The pedestrian of the sidewalk 11 is blocked from crossing.

As such, the present invention minimizes the detection error of the pedestrian signal lamp by detecting the green or red lighting state of the pedestrian signal lamp installed on the pedestrian crossing in direct or close proximity, thereby preventing an accident that may occur due to detection error .

Further, according to the present invention, a recording device is provided on the upper part of a pedestrian signal lamp so that an accident that may occur on or around a pedestrian crossing can be recorded, so that an occasional accident situation and an accident situation can be easily grasped.

The present invention also relates to a breaker equipped with a blocking bar isolating the road from both ends of the crosswalk, a bollard of the center line located around the crosswalk, and a safety fence separating the road and the ledge, and a signal synchronized with the pedestrian signal light So that the vehicle is stopped by the stop signal, so that the pedestrian crossing the crosswalk can safely cross the road without feeling threatened.
