According to some experts, in order to establish justice a criterion should be defined for each blessing, gift or each area and transportation can be considered as one of these areas. In this study, in order to investigate the justice status in the distribution of urban transportation services, five criteria of equal opportunity, difference, need, participation in public interest and entitlement were determined as the criterion for the subsequent investigations. The use of these criteria was based on different views and perspectives, and in addition, a number of them have been used in other studies. The numerical taxonomy was used to assess the status of Tehran metropolitan areas in terms of relative level of transportation development.

Finally, in the conclusion section , the implications of this situation were addressed and the strategies that can be taken into account in this regard were taken into consideration.
