Road traffic noise is closely related with urban forms and urban components, such as population, building, traffic and land-use, etc. Hence, it is possible to minimize the noise exposure problem depending on how to plan new town or urban planning alteration. This paper provides ways to apply for urban planning in consideration of noise through exposed noise estimation for urban planning alteration. Spatial autoregressive model which explains about 81.4% of road traffic noise from the former paper is used. The simulation results by the spatial statistical model are compared with those by the engineering program-based modeling for 5 small-scaled scenarios of urban planning alteration. The error from the limitation of containing informations inside the grid cell and the difficulties of reflecting acoustic phenomena is existed. Nevertheless, in the stage of preliminary design, the use of the statistical models that have been estimated well is useful in time and economically.

In urban areas, continuous monitoring and management of urban environmental noise and air quality are increasingly important for people’s health impact and well-being. Especially, the road traffic, which is one major indicator of urban forms such as population, building, transportation and land-use, etc., is the same emission source of urban noise and air quality. Furthermore it is required to figure out integrated relationship because the road traffic and other urban form indicators are interrelated. Therefore, this study aims to investigate the relationship among road traffic noise, air quality and urban forms, and to provide and consider the methodology. Fulton County in Georgia state of USA, where is the principal county of the Atlanta metropolitan area, is selected for this study. First, the noise level exposed to residents and the concentration of PM2.5 are calculated as dependent variables. Second, the representative values for noise level, the concentration of PM2.5 and urban form indicators are averaged over grid cells of 200×200m for Fulton County. And then, the relationship between noise and urban forms, and the relationship between air quality and urban forms are respectively estimated by spatial statistical model. In addition, the integrated relationship among them is analyzed by seemingly unrelated regression model. This well-estimated model could be useful for preliminary urban planning and sustainable environmental management, and it could make it possible to design integrated and systematic planning.
