我國的無障礙環境推動雖已提升至憲法保障層級，惟目前無障礙交通人行環境之營造甚少納入永續經營的概念。依據本文所蒐集國內外的相關文獻中，亦未單以無障礙交通人行環境的角度，來探討是否合乎永續發展的理念。 因此，本文嘗試以經濟合作與發展組織（OECD）於1996年所定義「永續運輸之9項發展原則」，來分析美國、英國、日本之無障礙交通人行環境推動是否符合永續發展理念。再以前揭3個國家之經驗，以及永續運輸之9項發展原則等角度，來研擬我國無障礙交通人行環境營造之相關法令修正、政策與相關配套、設計規範等建議。本文即希望透過這種開創性的連結，重新賦予無障礙交通人行環境營造的契機，使之具備永續發展的精神，也希望帶給後續研究者一種新的思考方向。 本文之研究範圍界定為交通人行環境中之人行道部分，但完整之無障礙環境範圍含括生活輔具、建築設備、建築物、交通運具、大眾運輸設施等，所以除了本研究範圍外，其他相關範疇仍需後續研究之努力，使完整的無障礙環境均能具備永續發展的精神。 / Though the implementation of barrier-free environment on Taiwan has been up to and assured by Constitution, the concept of sustainable development still seldom showed in the construction of barrier-free environment for the pedestrians. Moreover, in all domestic and foreign literatures conducted and analyzed in the study, it does not discuss whether the construction is consonant with the concept of sustainable development solely through the viewpoint of pedestrians’ barrier-free transit environment. Therefore, the study adopted the nine principles put forward by the NRTEE concern to explore whether the promotions of a barrier-free environment for the pedestrians by the U.S., U.K., and Japan are consistent with their sustainable development policies. Subsequently, the study tried to give suggestions on pedestrians’ barrier-free environment related laws, regulations, policies, and programs through examining the experience of previous 3 countries as well as the principles of OECD. The study hoped to realize the constructing concept of a barrier-free environment for pedestrians through an innovative link and to make pedestrian transport sustainable. Hopefully the study could lead researchers a new way of thinking. The research scope of the study is limited only in the sidewalks in pedestrian transport. The whole barrier-free environment, however, involves assistance facilities, buildings, construction facilities, vehicles, and public transport. Therefore, more endeavors on in-depth studies in previous related fields should be done to create an integral barrier-free environment with sustainable development spirit.
