Abstract
The utility model provides a pedestrian crosswalk safety facility. After the pedestrian crosswalk safety facility is installed and when a pedestrian crosswalk signal lamp turns green, a lock is opened, a pedestrian crossing a pedestrian crosswalk takes out a small green flag from a hole 3 in a lamp post 2 and holds the flag with hands to cross the pedestrian crosswalk. A driver in a turning vehicle knows that the pedestrian crosswalk signal lamp turns green and stops to give way to the pedestrian when seeing the pedestrian holding the small green flag. After the pedestrian crosses a road, the pedestrian inserts the small flag into a hole 3 in an opposite lamp post 2. When the pedestrian crosswalk signal lamp turns red, the small flag is locked in the hole by the lock, and the pedestrian cannot take out the small flag and accordingly dares not to rashly cross the road.
Description
Technical field
The utility model relates to the cross walk safety device.
