A smart crosswalk safety system for a pedestrian comprises bollard devices disposed in a sidewalk, each bollard device including a pedestrian identification sensor detecting a pedestrian, a camera photographing an area including the crosswalk, a beacon device transmitting a beacon signal toward the crosswalk when an operation signal is received from a control device, the control device generating an operation signal to drive the beacon device when the bollard device identifies a pedestrian who walks from the sidewalk toward the crosswalk and a pedestrian is identified to be present in the pedestrian identification area of an image captured by the camera, and a lock screen application installed in the pedestrian terminal of a pedestrian who crosses a street at the crosswalk to change screen of the terminal to a locked state when a beacon signal is received.
