Investigating the distribution of Tehran transportation services with emphasis on justice

According to some experts, in order to establish justice a criterion should be defined for each benefit or area and transportation can be considered as one of these areas. The experts relate the formation of a city’s texture to its transit network directly. An inequality in transportation distribution can form an unequal city. The purpose of this study is to investigate the formation of transportation services in order to find out to what extent the distribution of transportation services in Tehran city is based on justice and how can a better distribution be provided. In this study, five criteria of equal opportunity, difference, need, participation in public interest and entitlement were determined as the criterion. The use of these criteria was based on different theories. The numerical taxonomy was used to assess the status of Tehran metropolitan areas. The finding shows that, there are significant inequalities among the sectors and, on the other hand, the distribution of the facilities is not in favor of the deprived areas and benefits the advantaged regions. Finally, based on the results of the present research, transportation facilities should be distributed in such a way that the disadvantaged regions would receive more share than the advantaged regions. Establishing state-owned centers in less-developed areas can created demand for business trips. This will improve the situation of disadvantaged regions in terms of transportation services and advantaged regions in terms of some indexes like traffic, delays, waiting time at the bus stop, total travel time, crossing over capacity.
