Development of Evaluation Model for Urban Safety based on Sustainable Urban Metabolism

The purpose of this study is to develop a model for evaluating urban safety using the concept of sustainable urban metabolism. In this study, the framework of sustainable metabolism to assess urban safety consists of five principles and urban safety assessment processes that should be sought in its development; 1) Development of safety assessment framework based on urban metabolism applying the components of sustainable development; 2) Development of urban safety assessment framework based on urban metabolism capable of grasping the relationships between economic, social, and environmental elements; 3) Development of the framework capable of understanding all the network relationships between the components; 4) Development of the framework considering the outside elements influencing sustainable development; and 5) Development of the framework using urban safety assessment as the final result. Based on these principles, the structures of sustainable urban metabolism and urban safety framework were established, and then three processes were set to assess urban safety. In addition, based on the DPSR structure, we developed a basic model of urban safety evaluation for structural equations and System Dynamics.
