Abstract
To manage complex urbanizations, various advanced planning techniques have been developed. A last effort is the planning supporting system (PSS). This study intends to develop Integrated Zonal Impact Analysis (IZIA) System in Bangkapi District, Bangkok, by integrating land-use databases, transportation models, travel time and vehicle operating cost models, noise and air pollution models. Three unique characteristics are established: the zonal impact analysis framework, the impact interrelations in communities' viewpoints, and the community involvements in mitigating impacts. The system consists of four functions: problem and alternative identifications, impact assessments, impact integrations under public preferences, and information displays. As the results, most stakeholders prioritized pollutions (0.64) higher than travel costs (0.34). Therefore, planners should seriously consider the pollution problems. With the minimum impact costs, a shopping center project should be allocated into the radial network center. For two projects, they should be implemented beside the expressways. The proposed IZIA system was a successful preliminary application.
