Since the announcement and execution of the Zoning Act of Taipei Metropolitan in 1983, there is no obvious improvement on the living quality in the residential areas. Conversely, there are some issues on the usage classification and permitted usage categories. After further research, it’s found that the Zoning Act biased on the mixed-use, which permitted too much usage in one category. The most serious one was the permitted usage in its appendix, which made the usage of residential area almost the same as the commercial area.
After researching on the related documents on mixed-use, the study emerged the appropriate evaluation indicators. Then collecting the experts’ comments, the study modified evaluation indicators accordingly, which formed the bases of environmental evaluation of mixed-use. In between, the relative importance of top three indicators was ranked as “residents’ mutual help and guard”, “shopping convenience” and “dinning convenience”. Both “trash collection” and “waste water manipulation” were less concerned. It understandable that in experts’ concepts, the residential safety was the first consideration then the living convenience.
Based on the above evaluation indicators and collected comments from the residents and experts, the study came out the positive and negative values of evaluation indicators. The “quiescence and convenience of living environment” and “public safety” were positive value but “environmental pollution” was negative value. Summing up the big indicators, the value was positive which meant people possibly evaluated highly on the mixed-use in the residential environment.
Understanding the importance of indicators, the study rebuilt the operation model for compatible businesses, which calculated the values of business evaluation indicators and built mathematical model. Then the study found out that the greater positive values of summed up indicators, the more representative residents and experts accepted the business. The greater the negative value, the more exclusivity represented. More compatible businesses would less impact the environment but enhance the living functionality. Ranking the business sequences according to the needs of environmental quality in mixed-use, we could build up different grades of living environments by setting up different mixed-use standards.
It was proven from the study on the new and old residential areas that the mixed-use ratio of businesses would be differed by the width of road and location in which vertical and horizontal mixed-use are positively related. From the field study, the businesses in Ta-An district belonged to the metropolitan type but those in Wan-Hua district belonged to the tithing type.
In summary, the study went through the review and analysis of related thesis then built the evaluation indicators for mixed-use in residential area, which in turn were the bases to identify the businesses compatibility. Utilizing the evaluation indicators, we could identify the business compatibility and its impact on the living environment. Simultaneously, through indicator analysis, new business compatibility could be redefined and evaluate the relationship between evaluation indicators and business relativity. Especially for the business category, which would heavily impact the environment, the indicators could be identified as, e.g., voice and vibration pollution, trash manipulation, parking issue, air pollution...which needed more evaluation standards. After some time of execution, the results could be used to modify the evaluation standard, which would be the reference for the succeeding study of land mixed-use.
