Futures Study of the role of NewTowns in Establishing of the Balance of Physical Space Struture in Metropolitans with Land Survey Approach and policies

Achieving a regional balance which is compatible with each regions’s capabilities and potentials is one the policies of already approved land survey polices. Accordingly, the policy of consctruting new cities has been planned and implemented due to efficient and balanced distribution of population. The main objective of the research is to analyze the role of new cities in balancing the present and future physical space structure of Tehran metropolican area and to address the question of whether construction of new cities in Tehran neighborhood has been effective in attracting the suplus of population and developing a balanced area. The findings suggest that except for the the new city of Andisheh in Tehran metropolis (with realization of more than 75 percent of predicted population), other new cities have failed to attract the population or confronted major problems. In the study, the rank-size distribution method was adopted to identify the impact of new cities on physical space structure of Tehran metropolitan and the MicMac software was used to develop scenarios of spatial organizition development and the positioning of new cities. The results show that the new cities have no effects on the balance of physical space structure of Tehran metropolitan area and these new cities have failed to make significant impact of attracting poulation of the area with only a slight number, around 359,029 people ( 2.4 % of the area’s population ) in a 30-year period from 1987 to 2017.
