【 摘 要 】

Road traffic noise calculation method behind buildings included in the ASJ RTN-Model 2018 is an empirical model formula based on experimental results of a scale model. Therefore, the scope of the calculation method is formally limited in terms of building height, density, and distance from the road, dependent on the range of the experimental conditions. However, the roadside conditions in Japanese urban and suburban areas are diverse, and it is necessary to quantitatively investigate the validity of the calculation in such various conditions in order to widely expand the applicability of the calculation method. In European countries, creating noise map has been obliged by the Environmental Noise Directive, and the noise maps are strategically utilized for environmental noise reduction. In Japan, such a utilization of noise map is highly expected, and it is necessary to investigate an accurate estimation method which is suitable for Japanese build-up areas. In this study, we examined the validity of the road traffic noise calculation method in building complex by comparing the actual measurement results in some build-up areas around arterial roads.
