Abstract

This study developed a development density allocation model for sustainable urban development based on environmental carrying capacity theory and ubiquitous technology. The environmental standard of NO2 was used as the indicator to calculate the largest development density because it is a crucial air pollutant source in Korea. The process of allocating development densities consisted of 3 steps; trajectory analysis, air pollutants dispersion analysis, and development densities allocation. First, trajectory analysis was applied to pre-development conditions such as emission volume and locations. The additional pollutants emission volume caused by new urban development was inputted to employ the air pollutants dispersion model. Secondly, the air pollutants dispersion model was used to identify concentrations of air pollutants dispersed by the additional pollutants. Comparing air pollutant concentrations with environmental standards, the suitable population density of the development area was calculated. Finally, population density was allocated based on the results of the pollutants dispersion analysis. The results of the development density allocation model can be useful for preparing density and land-use maps in planning processes.
