This study suggested environment improvement by the "FUKUGAI" road construction system and considered the extent for the noise containment shell that produces significant noise reduction. The attenuation of noise by FUKUGAI requires that the position becomes equal from attenuation in distance of sound and decrement of the estimation noise level by the diffraction effect. The attenuation in distance and noise prediction by the diffraction effect are calculated by ASJ-Model 1998 (B method). For example, the extent of the system with a noise barrier was 12 times of vehicle headway distance. In this case, distance from the noise source to the estimation point, vehicle velocity, and the traffic volume are 20 m, 100 km per hour and 5000 cars per hour, respectively. The extent is different by distance from traffic volume and vehicle velocity and noise source to a traffic lane. This report describes our findings about the FUKUGAI extent, including some conditions and considerations.
