| Summary | The transit-oriented development (TOD) planning usually emphasized the development efficiency but ignored the other two aspects of sustainability: living environment and social equity. This study developed a multi-objective programming model to help planners to generate alternatives for TOD planning systematically and efficiently. Based on the concept of sustainability, three objectives were considered: maximizing the number of MRT passengers, maximizing the quality of living environment, and optimizing the social equity of land development. The decision variables were the ratios of floor space to site space (RFS) for different land uses in MRT station area. The constraints considered the limit of land use density, the combination of land uses, and the level of environment quality. Four types of stations along the blue line of Taipei MRT were studied. In addition to show the process of model application and the planning results, we also found that the area around CBD stations can achieve the largest number of MRT passengers, the area around neighborhood type stations can achieve the highest level of environment quality, and the area around transfer type stations can maintain the smallest deviation between station area and other area. According to the sensitivity analysis, the increase of the upper bound of residential RFS will significantly increase the MRT passengers, but the social equity and environment quality will both deteriorate. |
