Introduction ach form of urban development has its own characteristics and disadvantages or advantages. But the common denominator of all these development patterns has been responding to the growing development of cities and preventing irregular growth. In recent years, with the emergence of new ideas in various political, economic and environmental sciences, the growth and development of cities has become intelligently considered. Internal development is an essential part of smart urban development. Internal urban development policy is one of the three urban development policies that, along with other urban development policies; Connected or continuous development or separate or discontinuous urban development policy is proposed. In parallel with the horizontal growth of the city towards the suburbs and the destruction of lands and natural environment around the city, some spaces inside the city have been abandoned and have been left out of the development process. These abandoned spaces, called "infill-level" spaces, are important because they are located in cities, have underground or day-to-day facilities or equipment, and have access to such service centers and facilities. For example, in many of the old cities of Iran, the core of the city, which is considered in the form of historical and valuable worn-out texture, has such potential. The aim of this study was to investigate the effect of infill development strategy on the components of vitality and social desirability in the worn-out tissue of Zanjan city. Methodology This research project in nature is an applied investigation and based on methodology is considered attributive- analytical project. Also using GIS techniques and FUZZY-AHP model required maps was provided and in each map Zanjan city’s deteriorated areas infill development specified and in final map under studying area’s internal development characterized as low, average and high developed areas. The questionnaire was used to measure the variables of vitality and social desirability. The sample size is 382 questionnaires that have been selected from the statistical population of worn-out tissue of Zanjan city using Cochran's formula. The research findings show that infill development has a positive effect on promoting vitality and social desirability in worn-out tissues, and there is a significant relationship between infill development with vitality and social desirability variables. Therefore, it can be said that vitality and social desirability are significantly different from infill development (less, medium, high). Results and discussion 17 items have been selected to measure vitality, and according to descriptive statistics, vitality in the range will increase with increasing level of infill development. The rate of vitality score in neighborhoods with low intermediate growth development is 46.77, in neighborhoods with medium infill development is 52.63 and in neighborhoods with high infill development is 53.82. Also, each of the vivacity items is examined separately. The score of each of the items is between 1 and 6. To measure the level of social desirability, 14 items have been selected. The level of social desirability is improved according to the increase in the rate of infill development, and according to the average score of the social desirability variable, this can be realized. The rate of social desirability score in neighborhoods with low infill development is 44.98, in neighborhoods with medium infill development is 50.66 and in neighborhoods with high infill development is 52.12. Conclusion In studies of infill development, the potentials of different urban neighborhoods have been examined using the principles of infill development and its relationship with other variables has not been investigated. However, in this study, the relationship between infill development and the variables of vitality and social desirability in the worn-out context of Zanjan city has been investigated, which is a new discussion. This can determine the benefits of infill development. The findings show that the higher the infill development of neighborhoods, the higher the level of vitality and social utility. In the dilapidated context of Zanjan, neighborhoods with high infill development (neighborhoods above Imam Street) are in a better position in terms of quality of life and social acceptance than neighborhoods with low level of infill development (neighborhoods around the Husseinieh Azam Zanjan). Therefore, it can be said that the higher the level of infill development, the better the security, the beauty of urban spaces, the diversity of activities, the physical diversity, the presence of women in the place, the compatible uses, the vitality of the citizens, and so on.

Introduction Considering the occurrence of scattered phenomena in the cities of Iran, the need for re-planning on land and housing in old textures has doubled. In fact, urban sprawling growth shows that the city's population growth is lower than the physical development of the city. Infill development provides the best opportunity to maintain outdoor space and optimize the use of existing infrastructure. And at the same time, by promoting identity in areas where abandoned land is redeveloped, while providing housing, especially for the low income, can provide a model for urban development policies, especially in the housing sector. In general, issues such as the lack of land, the destruction of agricultural land and gardens due to the excessive spread of cities, the energy crisis, air pollution, informal settlements, the spread of cities on hazardous areas and faults and social anomalies, including issues Which make it imperative to pay attention to the infill and sustained development approach in the housing sector. Methodology Thus, in this study to investigate the role of infill development at renovation of Hokm Abad region of Tabriz old texture we applied spatial analysis. By calculating the indexes of infill development and old texture and corresponding maps, the final map of Infill development in the neighborhood with 95% confidence level came out. In addition, there are street network restrictions for infill development the relationship of which is also being approved through a map to exclude the respective problems, to come out of a state of exhaustion and regain its life as before. Result and discussion The overall results of this article suggest that: There is a high talent for the development of vacant land between existing parts (10% of the total land), which can be used for residential development by increasing the use of the density of buildings and increasing the use of lateral land uses of housing land use. Considering that neighborhood development has taken place at the Horizontal surface can Aggregate of fine-grained pieces, which accounts for over 50% of the area in question, the existing construction density can be increased. According to the buildings' life plans, the materials used, the quality of the building, most buildings need to be fully renovated and restored. In the new rebuilding, the principles and criteria for infill development should be considered as an example of the new urban planning principles, so be build new development based on the human scale, neighborhood the centerpiece with a distinctive center and edges with the ability to walk and bike ride. According to population density map 1.3, the population increase can be done in empty spaces and points marked on the population density map. Most of the transit network in the Hakam Abad district of Tabriz are organic and have not complied with the relevant rules and regulations that should be amended in new constructions Improved passageways and extensions of less than 6 meters, and attention should be paid to the rules for the extension of old texture tracks transit of at least 8 meters (Local access). Conclusion New towns are creating unbridled areas around the large cities and metropolitan regions witnessing, the sprawl development, the increase of urban costs, and finally untold magnitude of urban and urban management facing up complexity and trouble. And the creation of new towns cannot lead to the important goal of attracting new towns not only in the metropolis crowd overspill, but Some have not yet reached the stage of exploitation after some years. According to this issue the focus should be on the managers agenda and municipal officials rather than the urban sprawl development around the cities The spreading cause of fertile agricultural lands can blight available (old textures) usage, The decline of urban life in urban centers revives the past new towns are creating unbridled around the large cities. This matter causes sprawl development, the increase of urban costs, and finally untold magnitude of urban and urban management facing up complexity and trouble. And The creation of new towns cannot lead to the important goal of attracting new towns not only in the metropolis crowd overspill, but the operational out comes as well. According to this issue the focus should be on the managers agenda and municipal officials rather than the urban sprawl development around the cities the spreading cause of fertile agricultural lands can blight available (old textures) usage. Therefore, infill development and utilizing existing capacities can help solve problems both in terms of exhaustion and lack of services, and infrastructure and Superstructures. It can resolve to promote awkward urban development discipline.

Urban population growth and increasing demand for housing and services in the cities of the country has forced the need for physical development of cities this development in recent decades has been more of external development, and the provision of services and housing has been following by adding to the city's area, that has caused to urban sprawl and deterioration of surroundings and neighboring gardens and agricultures. While that infill development and particularly redevelopment and utilization of land as effective approaches can be considered in reducing damage to the environment and realization of sustainable development of cities. In this regard the aim of this research is to develop a model to identify lands with redevelopment capability and use it to the city of Arak as an example. Therefore, this research tries to answer these questions that how to identify the lands with redevelopment capability? And what are these areas in Arak? For this purpose, an innovative algorithm to identify lands with destruction and redevelopment capability is designed, that urban parts are evaluated on the basis of 8 criteria, construction quality, age of Construction, small lot, permeability, land's price, sponsorship rate, ratio of migration and access to green space. This innovative algorithm has been implemented for example in the city of Arak. The results show that innovative algorithm has nice capability in combination with GIS software and can be used to identify the lands with destruction and redevelopment capability. Also using this algorithm in Arak city lead to identify 4187 pieces with redevelopment capability which has an area of 85.8 hectares and can be used to realization of infill development in Arak city.
