Success and Failure in Metropolitan Regions Organization Comparative comparison of east pivot of metropolis Tehran and east pivot of metropolis Paris

For a long time, East pivot of metropolis Tehran has been playing an efficient role in spatial urban and rural habitationdevelopment in its region; so that in different periods this capacity and potential caused the pivot develop rural andurban habitations without meeting planning rules and requisites. Lack of schedule, and scattered, however, createddisorganization and unfavorable conditions from different economic, social, environmental, and demographic aspects.Accordingly, the government has taken decentralization in Tehran into account based on new cities experiences inother countries and in order to decrease the population load, and also constructed and developed Pardis new town toorganize habitation on this pivot in order for eliminating regional unfavorable conditions around Tehran. After morethan two decades of Pardis new town construction, however, failure and success of this policy has received attention.Hence, this research serves to consider and comparatively analyze east pivot of Paris (as a successful instance ofEuropean new cities) and the one of Tehran. Research methodology is comparatively analyzing these two instances bymeans of spatial cartographic analyzes and comparative comparison of data related to spatial and skeletal characteristicsof studied areas. perceived results indicate that planning without considering spatial relations between activities andhabitation and a simple point attitude towards habitation are of main causes of failure in management and equalizingeastern region of metropolis Tehran. That is, new town Marne-La-Vallee in east of Paris comprises all houses andeven old rural centers on its base beside spatial capacities of new development, whereas only determining the range ofdevelopment and new buildings are considered regardless of habitations interrelations between Roudehen, Bumehenand Jajrud, and relations between other existing habitations in this pivot or spatial order has been neglected.
