PURPOSE: A bollard is provided to prevent traffic accidents which are possibly happened in a crosswalk without traffic lights by calling a driver’s attention. CONSTITUTION: A bollard comprises a base unit (110), a main body (120), and an impact absorber (160). The impact absorber is interposed between the base unit and the main body to bend the main body towards one side when being applied by a lateral external force. The impact absorber restores the main body to an original position when being released by an external force. The main body comprises a signal indicating light (130) for selectively lighting red and green lights along with the switching operation of a pedestrian and a light projector (140) for irradiating light to a crosswalk in the night. |
