Introduction and Goals: Sustainable transportation is comprised of an integrated set of dynamic and continuous policies and guidelines, including economical, social and environmental goals which involve fair distribution and effective use of resources in order for next generations and also society’s transportation requirements to be met.The effects resulted from these sections will determine the method of orientation towards this goal. Till now, no common definition has been provided for sustainability.However, both sustainable development in general, and specifically sustainable transportation are seeking to find a balance between environmental, social and economical qualities, in provision of transportation facilities. Accordingly, sustainable transportation is an approach that “Reflects socio-environmental costs”.Method: This descriptive- analytical research is based on documentary-library studies.Through ANP (analytical network process), we have tried to consider all aspects in data analysis, including internal and external relationships between the elements constituting decision network, such as all alternatives, criteria and sub-criteria, so that, a conceptual model of ANP could be developed after classification of data.Findings: ANP model including numerous clusters and alternatives has been developed via Super Decision software and the results from examinations made in the software were analyzed. Eventually, some of the results are referred to in this research, due to high volume of the outputs.Results: The results show that, in evaluation of sustainability of urban transportation network in district 21 of Tehran as a case study, following levels of priority have been obtained in respect of regions: 1- Region two, 251371.0, 2- Region one, 616064/ and 3- Region three, 132565.0.
