Evaluation of make smart indicators in Yazd city using ANP model and GIS analysis

The accelerating trend of urban development that has dominated the cities of the country in recent years and the adverse consequences of such development have already raised. the need to change the prevailing views on urban planning and attention to the application of smart urban growth in urban development plans and programs. The establishment of a smart city is an indisputable necessity to get out of the urban planning crisis and solve many problems in cities. The aim of this study was to make decisions in a smart city based on the knowledge obtained through spatial data mining in Yazd City using a descriptive-analytical method and the ANP model.

The present study is applied in terms of purpose and descriptive-analytical in terms of nature and method. Some theoretical data were collected through library studies, reports, and dissertations related to the research topic. Then, based on the studies, appropriate indicators along with their measurement method were determined. In the next step, the required data were collected, edited and prepared. Compactness, access to public transportation and environmental factors were selected as indicators. For the physical spatial analysis of the urban areas, the ANP model was selected from the models and indicators proposed during the research process. Then, the indicators were formed in the Super Decision software as clusters and components within these clusters. Finally, the selected indicators in the five districts of Yazd were examined and prioritized from the perspective of smart growth. Since this method is used in addressing the elite community, 1 to 4 experts were considered to be sufficient to implement this method. However, to reduce the bias of the results and increase the reliability of the data, 15 experts in the field were selected. In the next step, a questionnaire was designed for the pairwise comparisons of the criteria and the sub-criteria and filled by the target community. In order to integrate the collected data, their geometric mean was calculated and then examined from the perspective of individual judgments and elite community. Finally, the results of network analysis and digital GIS layers were combined and the urban spaces of Yazd were analyzed and evaluated based on intelligent growth indicators.

According to the pairwise comparison, the weight of the population density sub-indices was 0.66, which was higher than that of the other sub-indices. Also, the weight of the sewage route sub-index was 0.001, which was less than that of the other sub-indices. Among the access, compaction and environmental indices, the access index with a weight of 0.45 had the highest value, and the valuable environmental index with a value of 0.23 had the lowest value. The weights of the sub-indices and indices were applied in layers. Highly talented selected areas are located in the northwest, center, southeast and southwest of the study area. They include the southern part of region 1, the western part of the historical region, the eastern part of region 3 and the western part of region 4. According to the obtained weights, the historical region with a weight of 0.35 has the highest potential in terms of the intelligence indicator; Regions 3, 4, 1 and 2 had the weight of 0.19, 0.18, 0.13, 0.12. The historical area, which is also the center of the city, has a dense texture. The establishment of such places as administrative, commercial and medical has caused citizens from other areas to come to this area. The other areas of Yazd have no justice in the distribution of land use.

of results The accelerated trend of urban development that has dominated the cities of the country in recent years and the adverse consequences of such development have made it inevitable to change the prevailing views on urban planning and to pay attention to the application of smart urban growth in urban development plans and programs. In this regard, it is necessary that the concept of smart growth be introduced in principle in all the dimensions and areas of the city life and be used as a basis for organizing the performance and communication among them. Therefore, in order to achieve sustainable urban development in Yazd, the smart growth should be considered as the main strategy. This not only preserves the environment but also prevents the uncontrolled expansion of the city and reduces the volume of travel in the regions. To achieve such sustainability, it is necessary to do planning based on the knowledge of the current situation in the whole city. The purpose of this study was the spatial analysis of the urban smart growth indicators in Yazd through a descriptive-analytical method. The study area consisted of five regions in Yazd that were evaluated in terms of compliance with urban smart growth indicators. The results of the study indicate that the physical growth and development of Yazd City has gone through ups and downs over the years, so that its urban area has exceeded 100 square kilometers. This development has occurred unevenly, in an uncoordinated and scattered form and without considering the spatial distribution of urban land use.
