Expressway development and operation should, therefore, be planned with careful consideration of the environmental impacts. An assessment of an expressway project may include consideration of different routes as distinct alternatives. Thus, evaluating alternatives is an important step of environmental impact assessment. In this paper, some MCDM (Multi Criteria Decision Making) models, were used for assessing alternatives in EIA in earlier studies, reviewed and a hybrid MCDM model proposed to tackle the dependency relations of evaluation criteria with aid of the fuzzy DEMATEL (decision-making trial and evaluation laboratory) method. In next step, the fuzzy DEMATEL method combined with ANP (Analytic Network Process) method to weighting criteria for assessment of alternatives with aid of the fuzzy VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje) method. Empirical study results illustrate the proposed model is a workable and reliable tool for evaluating alternatives of environmental impact assessment of urban expressway in order to make results much closer to reality. http://pubs.sciepub.com/ajcea/5/4/2/ajcea-5-4-2.pdf urban expressway EIA fuzzy DEMATEL combined with ANP fuzzy VIKOR and MCDM model
