One of the most complex social phenomena in today's cities is inequality. This inequality in urban space has led to problems, especially in metropolitan areas. One of these issues and problems is the social exclusion of some citizens in the urban space. The purpose of this paper is to survey urban space in terms of indicators of social exclusion.

The present paper is applied in terms of purpose and descriptive - analytical in terms of method. First, the data were collected using questionnaire tools for indexing and then Shannon entropy method was used to weight social exclusion indices. The target neighborhoods are then ranked and leveled based on the Coopers model and analyzed spatially through a map in ArcGIS.

According to the indicators of social exclusion from a total of 13 neighborhoods, the residents of 4 neighborhoods, all of which are located in the northern part of the region, do not suffer from social exclusion due to their social context, economic situation and access to political power structure. While the neighborhoods of Bazaar, Imamzadeh Yahya, Sangalaj and Harandi, which have the largest population and area and form the old and central core of Tehran, are severely socially excluded in terms of socio-cultural, economic- structural and political-civil dimensions. And the other 5 neighborhoods are in a moderate situation in terms of social exclusion.

A study and recognition of the concept and indicators of social exclusion and their evaluation in the urban space of District 12 of Tehran Municipality shows that although this area is located in the heart of Tehran in terms of geographical location, But it is not possible to provide social, political and economic opportunities for all its inhabitantsAnd some of its neighborhoods are considered isolated spacesAnd some neighborhoods are considered excluded spaces.

The urban landscape is the art of visual and structural integration that is perceived and monitored by the observer spatially. The subjective perceptions of residents of the urban landscape regeneration and the factors that influence these perceptions are of great importance. This perception is more sensitive to planning and designer interventions in the city’s fabric and structure, especially in historical cities with valuable elements, history of mentality, and identity. Therefore, it is necessary to identify the factors affecting mental perception and residents’ perception of space and urban landscape. To explore this issue, we employed a two-step mixed approach: First, a qualitative method with Delphi technique was used specified for each sub-criteria and then 500 members in the District 12 were interviewed using a Liker-based questionnaire. The results of the exploratory factor showed that all the terms could be found in the 10 final factors, which explain more than 65.8% of the total variance. Based on the results of this study, the perceived components of urban landscape from a resident and active perspective include visual attractiveness, ease of access, Legibility, diversity and harmony, reduction of visual disturbance, attachment, adaptability, and the variety of ultimate determinants affecting the urban landscape regeneration. Therefore, it is suggested focusing on refining the fabric of these factors using the participation of people.

It is true that Central part of Tehran is important commercial, political and administrative center of Tehran. While many BRT and subway lines are being operated recently, domestic bus system are not changed harmonically. It compels urban and traffic managers to revise the bus transit system. The purpose of this paper is to identify the most important possible measures for revising the bus transit system and to examine the effects of this policy on improving transport, environmental, physical, and socio-cultural dimensions in region12. Firstly, with Delphi technique, the most important solutions for this policy were identified then, using Chi-square test, a significant correlation was found between the research indices. Using the Friedman test, the three-dimensional transport, environmental, physical, and socio-cultural indicators were ranked.
The results show that the socio-cultural, transport and physical-environmental dimension will receive the greatest impact from this policy respectively.
Also, investigating on demerits and obstacles of this policy reveals major factors compromised the necessity of coordinating with the bus system of regions which are in vicinity of region12, and increasing the number of trips;
while the most important obstacles to the implementation of this policy are the interference of the tasks of the decision-making bodies, and the absence of specialist personnel.
In the following, experts were questioned about the potential of each of three actions of the policy and the results showed that the locating passenger hub in the boundaries of the region has the highest potential to operate respectively.

The criteria and standards of green space development should be specified before any planning for green space development. The cities'' conditions not only rule the creation of vast and more importantly planned and organized green spaces but also demand vast green space in order to establish ecological balance against made environments. This research tries to study green space per capita in region 12 of Tehran with regard to green space criteria determined، such as the local climate characteristics، environment quality and density of people in room in resident units. Then، considering these criteria، the green space per capita in region 12 of Tehran was specified. Green space per capita for each person is 5. 12 m2 in region12، which considering the above criteria should be increased to 35 m2 for each one. It is concluded that the maximum amount of 12 m2 for each person، which was proposed by Ministry of Housing and Urban Development for all cities، is not logical and per capita of each city should be calculated with criteria and environment condition of the city.
