 In the present era, planners are required to adopt appropriate policies for the proper deployment of land uses in the form of principles of sustainable land management. In this regard, the necessity of locating site of major commercial centers is to a great extent considered as one of the influencing factors on cities economic success.

Shopping auto mall centers require proper site selection in order to prevent the dispersion of their service centers due to the widespread provision of services and the growing need of citizens for cars. Therefore, the present study aimed to locate the construction site of an auto mall shopping center in Gaz-e-Borkhar.

The research method is based on spatial data analysis based on comparative studies and field evaluations. The selected criteria included access to services and communication ways, hazards in terms of privacy and flooding, landscape and climate form whose digital layers were prepared based on spatial maps and data, and were analyzed in ArcGIS software environment. To determine the relative weight of the parameters, quantitative analysis was performed and prioritized by pairwise comparison. Finally, by combining the layers based on their weights through weighted means method, the zoning map of the area was prepared for optimal regions to create a shopping auto mall center.

The results of the research categorized the study area into five zones ranging from very appropriate to very inappropriate to construct a shopping auto mall center. Zones 1 to 3 due to low land use, and Zone 4 due to intersection with the agricultural lands were not ranked as optimal. But, the 5th zone (very suitable) because of the intersection with the residential areas and the existing aqueducts, was classified into 4 sites from south to southeast of Gaz-e- Borkhar. Respectively, Site 1 was very desirable (82.593 hectares), Site 2 strongly desirable (56.359 hectares), Site 3 desirable (21.158 hectares) and Site 4 with low desirability (11.346 hectares) were prioritized, respectively, as suitable places for constructing a shopping auto mall center. The first place (site 1) has the highest function and performance.

The present study has presented a spatial graphical representation of  Gaz-e-Borkhar city in the form of capable zones for constructing a shopping auto mall center that can be a comprehensive guide and scientific document for managers and planners to make the constructive decisions and to implement developmental policies.

The increasing tendency of man to the life of the car and the use of personal vehicles, the lack of utilization of public transport, the increase of environmental pollution and, ultimately, the movement of society to individual life, diminish social interactions and distant Human beings are from each other. The approach to turning some of the streets into a pedestrian that removes or reduces traffic in the central part of the city is to improve the quality of the environment and increase the vitality of these spaces. The present study attempts to evaluate the feasibility of the implementation of a pedestrian-centered plan in Khajeh Nasir Street, located in the historical context of the city of Gaz-e-Borkhar. The research method used in this research is a descriptive-analytical approach using library studies and expert interviews. Analysis of the variables used was done using spss and Amos softwares. In the first issue, the implementation of the pedestrian plan was considered in terms of transportation dimensions. The results of the first hypothesis test showed a significant relationship between the variables studied and the first hypothesis was confirmed. In the second hypothesis, we examined the feasibility of accepting the implementation of the plan from the point of view of the business and citizens. The results of the second hypothesis test showed a significant relationship between the measured variables and the second hypothesis was confirmed. Also, the results of the second-order factor model showed that the economic factor has the highest gain with regression weight of 0.86. Subsequently, the social and physical factors with a regression weight of 0.82 and the environmental factor with a regression weight of 0.44 are in the next rank. The results of this study indicate that the implementation of the pedestrian plan in Khajeh‌e‌_nasir Street is acceptable for citizens and businesses and will not cause any problems in terms of traffic and traffic dimensions.

Introduction Today, due to the rapid growth of urbanization, the mismatch of today's streets with the need of the population, the placement of crowded applications on the edge of the city streets and the placement of incompatible uses together have caused traffic congestion in cities. Traffic phenomena are one of the major problems in most large and even medium and small cities. This is one of the social problems of today's societies and cities. Although extensive studies have been conducted on the structure of the network and the use of the device separately, their interrelationships have been neglected (castmost, 2003: 19). The central texture of the city of Kashan, on the one hand, is based on the history of the city, which has attractive elements of the population such as the old Kashan bazaar and historic buildings and schools on the one hand, and streets embodying a vibrant population such as commercial, educational, and health use, on the other hand, a large population throughout the The day, especially during peak hours, absorbs traffic, causing severe traffic congestion in this tissue, therefore, it is necessary to pay attention to this problem and to re-distribute the space of absorbent applications of the population in this tissue. The present study evaluates the role of land use in creating urban traffic in the central part of Kashan and the re-distribution of spatial uses and identifies the relationship between the distribution of medical applications and urban traffic. Methodology

Nowadays, rapid urbanization; mismatch between modern streets and the demands of population; population attracting land uses along streets; and vicinity of incompatible land uses have resulted in traffic congestion in cities. Traffic is one of the major problems in most large cities, and even medium and small cities. It is also one of the social problems of modern societies and cities. Although, extensive studies have been carried out on the network structure and land use separately, their interaction has been disregarded. Like other modern cities, the city of Kashan faces this problem. The central texture of Kashan attracts a large population throughout the day, and especially during rush hours. This is on the one hand, due to the presence of historical elements, such as Kashan historical bazaar, historical buildings and schools, and on the other hand, because of population attracting land uses like commercial, educational, and therapeutic land use. Therefore, it is necessary to consider this problem, and the spatial redistribution of population attracting land uses.
Materials & Methods : The present study applies a descriptive-analytic methodology. The necessary information was collected using library research, documentary method, and expert interview. Then, the data was entered in GIS software. GIS software and network analysis model were used for data analysis.  Results & Discussion: In this study, the role of educational and therapeutic land use in traffic congestion in central areas of Kashan was investigated. To carry out network analysis, the network map of Kashan streets and their operating speed were required. The street network was depicted in GIS software. Then, the maximum operating speed of the main streets of Kashan was determined based on the master plan. Table 1 presents operating speed in five main axes of Kashan based on the master plan.  These include main and crowded streets of Kashan. The operating speed of other streets was collected through expert interviews. After designing the network and determining operating speed of streets, (educational and therapeutic) land uses with the most significant impact on the traffic congestion of Kashan were identified by interviewing ten experts, with the aim of determining service areas. For each sample land use, a test was performed to determine service areas in the network analysis phase. To conduct this test, the standard service radius of educational and sanitation land uses in Iran was used. In network analysis, the test was separately conducted for each primary school (minimum operating radius of 4 minutes/ maximum operating radius of 5 minutes), middle school (minimum access radius of 6 minutes/ maximum access radius of 7 minutes), high school (minimum access radius of 8 minutes/maximum access radius of 10 minutes), and therapeutic land uses (minimum access radius of 7 minutes/ maximum access radius of 8 minutes). Based on the analysis of service provision range in Kashan downtown, we conclude that compared to other areas in the city, primary schools (in their minimum access radius) face 2.25% increase in traffic congestion; middle schools in their minimum radius of access face 4.67%, increase and in their maximum radius of access face 1.83% increase; high schools in their minimum radius of access face 3.25% increase, and in their maximum radius of access face 7.95% increase, and therapeutic land use in their minimum radius face 7.46% increase, and in their maximum radius face 6.16 % increase in traffic congestion. However, primary schools in other areas of the city face 0.24% higher traffic congestion in maximum access radius as compared to downtown. Thus, downtown attracts 13.13% more unnecessary urban commutes and traffic in its minimum radius of access. This reaches 20.68% in the maximum radius of access, which is due to a larger overlap between educational and therapeutic land u
