Multi criteria decision making for sustainability assessment of carsharing

Confronted with negative environmental impacts, rising fuel costs and increas-ing congestion, many cities are implementing sustainable mobility measures to improve the flow of passenger and goods. Examples of these measures are use of public transport, cycling, walking, energy efficient vehicles, biofuels. The challenge before transport decision makers is which one(s) to choose for im-plementation as often there is no or limited quantitative data available on the subject. Moreover, the context of each city, its geographic and transport condi-tions restrict the generalization of results obtained in experienced cities. In this paper, we investigate four multicriteria decision making (MCDM) techniques namely TOPSIS, VIKOR, SAW and GRA for sustainability evaluation of urban mobility projects under qualitative data and demonstrate their application through a numerical example.
