PROBLEM TO BE SOLVED: To solve the problem of a transparent sound insulation wall that transmits the sun light causing a road to deteriorate, making a driver feel dazzled, or making a person receiving the sun light feel hot.SOLUTION: A member is composed of one or a plurality of shaped resin sheets having one surface including a salient whose height is equal to or higher than 1 cm and equal to or lower than 10 cm. A traffic sound insulation system with a power generation function is constructed by installing a sound insulation wall, at least part of which is made of the member, on a side face of a road or a track. The member enables a driver to enjoy the scenery of an express way or around a track without feeling dazzled or hot so much; and makes it possible to obtain a sound insulation wall capable of suppressing deterioration of a road caused by exposure to the sun light.SELECTED DRAWING: Figure 2 |
