A system dynamics approach to the simulation of urban sustainability

This paper is a continuing effort to develop a framework for an indicator s ystem to measure Taipei's sustainability (Huang et al.[1]). In order to stu dy the interactive behavior of sustainability indicators, an urban systems model is developed which consists of six subsystems: land use, population, transportation, water resources, solid waste, and waste water. In all, four teen urban sustainability indicators are included in the model developed. U sing Taipei as a case study area, STELLA software is used to simulate the c hanges of indicators overtime. Three scenarios are formulated to study the likely effects of different urban policies on Taipei's sustainability.
