Regeneration model of Taiwan old urban centers - A research framework of a performance evaluation system for a livable urban district

The researchers explore the current urban redevelopment problems in Taiwan old urban centers. Based on an indicator system framework, this study proposes a regeneration model-a performance evaluation method for a livable urban district, composed of four constructs, and 21 general indicators and 62 policy-making indicators. The four constructs are land use sustainability; transit oriented development (TOD) pattern, district composition, and architectural typology and estate. Considering this framework feasibility, the researchers recruited a panel of experts for judgment of priority for the indicator system in two phases of questionnaires. The first phase uses the fuzzy Delphi method (FDM) for experts to decide each policy-making indicator and the degree of importance of that indicator. The second phase uses the analytic hierarchy process (AHP) to determine the priority of the four constructs and that of each general indicator. Since panel experts from various disciplines and regions evaluate this indicator system with priorities, the current study discusses the variance of priorities caused by different panel experts. This AHP framework serves as a guideline for local government to proceed with regeneration plans toward livable districts, or a framework to evaluate the performance of regenerated old urban districts.
