Nowadays, urban planners are encountered with Urban sprawl in the large cities, especially in the developing countries. In order to control this condition they have taken different policies, one of these policies are increase density. The aim of this research is to determine the optimal building density in Isfahan's fifth district. To analyze this subject, firstly the selected district was divided into several quarters (neighborhoods), the indicators in each quarter were studied and weighted according to their suitability for the proposed density, then the weight of each index was established by the use of comparison matrix and eventually the suitability of each quarter was determined to propose the increase of density. The findings of the presented research indicate that because of the specific qualifications of the district, such as the existence of the valuable historic fabric of Jolfa and its neighborhood with Zayande-Rood, the historical center of the ChaharBagh-e-Bala and width of the passages and …, it`s better to avoid the increase of density in this district; and finally some suggestions is presented in order to determine an optimal density for this region.

  The major style of urbanization in Isfahan has been always conventionally based and focused on pedestrianism. This city whose frame and structure is organized and nearly completed in the Seljuk and Safavid eras, still (particularly in the old areas) is under a system based upon evaluation of the qualitative properties of districts and maximum connection between people  and environment .Though from early  20^th century and the start of modern transformations in architecture and urbanization in Iran, building new and modern districts with central focus being on maximum usage of land to build infrastructure and paths for passing cars, the pedestrians are less valued .Regarding this point that city development and description of new necessities by humans has inevitably new activities and utilizations in definition of districts, by comparing the new and old districts of Isfahan we can significantly come to the conclusion that how each one`s frame work properties can satisfy today human beings' requirements and interactions and what the strategies for their adjustment and promotion are .This article compares the capacity of pedestrianism and social interactions between an old and a new-fashioned district in Isfahan in order to discuss the strengths and foibles of them. The discussed titles are: aim of research and the way of that, reviewing the supplies about new urbanization and walkability, checking pedestrianism in two districts of Isfahan, and the results of the research .The final parts discuss the results of the review and physical position of two intended districts. Finally, the implications will be presented as guidance principles to design new-fashioned neighborhoods in order to improve the quality of neighborhood and social interactions due to the walkability.
