永續運輸指標與策略之整合模式

Abstract

永續的運輸發展必須是在考慮目前及未來長期的狀況下，仔細審視所規劃的運輸系統與大自然和社會間的互動，其中必須要預測所有與計劃相關之變數未來可能的變化，例如地理與生態條件，社經條件，社經條件尚包括社會價值系統的潛在變化。運輸設施和運輸活動對環境、社會和經濟會產生顯著的衝擊，因此永續運輸發展必須考慮到多個準則。多準則最佳化方法則是在同時考慮多重準則下，設法求得一個可接受的妥協解之方法，多準則最佳化是一個複雜且具動態性的過程，經由此過程可以分別達成管理層面及工程層面的目的。妥協排序法(如VIKOR與TOPSIS)則是經常被用來求解多準則最佳化問題之方法之一，本研究首先建立永續運輸發展的評估架構，並且被作為最佳化評估之準則，接續發展出永續運輸指標與策略之整合模式，並利用多準則最佳化之妥協排序法，提出永續運輸策略之優先次序。

Sustainable transportation development requires consideration of the interaction of a planned transportation system with nature and society under present and long-term future conditions. It requires prediction of possible future changes in all variables relevant to the plan, e.g. geological and ecological conditions, as well as socio-economic conditions, including a potential change in society’s value system. Transportation facilities and activities can have significant environmental, social and economic impacts, and sustainable transportation development is a multicriteria task. The multicriteria optimization method may be applied to achieve an acceptable compromise. Multicriteria optimization is considered as a complex and dynamic process in which one managerial level and one engineering level can be distinguished. The compromise ranking method (known as VIKOR) is introduced as one applicable technique to implement within multicriteria optimization. The multicriteria model can treat all relevant conflicting affects and impacts in their representative units. It is assumed that a framework for building evaluation indices has been developed for sustainable transportation development. The established evaluation indices will be a basis for the optimization criteria. The integration model of sustainable transportation indices and strategies sustainability will be developed as a main project goal. The strategies sustainability will be determine by multicriteria ranking of generated strategies, and the priorities of sustainable transportation strategies could be proposed.
