description PROBLEM TO BE SOLVED: To secure safety of a nighttime walk, and to improve electric power- saving by blending a fluorescent pigment with a road surface indicating material, installing an ultraviolet lamp with a sensor, irradiating a road surface by sensing person and a car, and emitting the fluorescent light from the indicating material. SOLUTION: A fluorescent pigment is blended with a road surface indicating material 1 of a pedestrian crossing and a temporarily stopping line so that the light is emitted by lighting an ultraviolet lamp. The ultraviolet lamp is arranged on an overhang type support 2 to be automatically flashed by a signal from a pedestrian sensing sensor 5 and a vehicle sensing sensor 6 so that the road surface indicating material can be clearly and visually confirmed even at nighttime and rainy weather time. Among the ultraviolet lamp, a black light for cutting off visible radiation is used to enable a vehicle driver to visually confirm the road surface indicating material 1 and a pedestrian even from a distant place in a surrounding dark environment to secure safety of the pedestrian on the pedestrian crossing in the night to thereby avoid light damage to neighborhood residents and nature as well as to serve as a power-saving measure.
