Analysis of the Consequences of Sales of Surplus Density at zone 2 Tehran city.

Density can be defined as a benchmark or a measurement system. The economic dimension of congestion is perhaps the most important issue in this category because the national economy, local economy and household economics directly affect urban density. On the other hand, the land value is very important, and on the other hand, financial power, operating factors and urban management in helping housing programs, providing land and housing, as well as urban services, all contribute to the formation of the nature of urban congestion and the realization of density The projections are effective in urban development projects. The purpose of this study was to analyze the consequences of surplus sales on zone 2 of Tehran, which was done by descriptive and analytical method. And after the conclusion, the data analysis method was used with the swot model to access the results. The study zone is Tehran 2 District. The results of the research have shown that the sale of surplus congestion by municipalities has disrupted the population density scheme approved by the Urban Organization and urban design. In addition, there was a shortage of service use, increasing congestion and becoming a bed of land and housing. The consequences of this policy in various economic, social and cultural aspects have led to an increase in the price of land and housing, an increase in the costs of the production sector and urban services, the weakening of urban laws and regulations, and the loss of urban identity.
