| Summary: | 碩士 === 國立交通大學 === 交通運輸研究所 === 90 === “Sustainable Development” is generally discussed by three objectives：social equity, economic efficiency, and environmental preservation. Since transportation sector may generate some negative effects on these three objectives and intercity transportation has some special characteristics, the sustainable development of intercity transportation becomes an important issue. Although the conflicts exist among these three objectives, this study focused on the social equity for which was seldom discussed before. The purpose of this study is to build an indicator system to evaluate the sustainable development of intercity transportation in the social equity aspect. Based on this indicator system, the national sustainability of intercity transportation can be measured and the development strategies can be designed.
The goal setting method and some setting principles were used to generate the initial indicator set. Based on the examination of functional overlap, the survey of AHP questionnaires, and the feasibility of data acquirement, the final indicator set was decided from the initial indicator set. The fuzzy inference method was used to integrate the final indicator set and the fuzzy rules were built by the Matlab package. The “max-min” method and the “center of gravity” way were used to be the defuzzifier.
The results of this study show that, the degree of sustainable development for intercity transportation in Taiwan is “Medium” in the social equity aspect. The essential transportation needs of elders and the disabled are not satisfied enough. Private vehicle users do not play the reasonable cost. In order to improve these unsustainable phenomena, different strategies were designed and evaluated in this study. We found that the effects of most proposed strategies are insignificant. It was concluded that more strategies should be proceeded in parallel to generate significant improvement.
