Urban streets are dynamic spaces with a sense of movement, which are designed for use by pedestrians and riders, or sometimes only on foot.These spaces often do not respond properly to the needs of the people who use them, and people look at the street as a path just for riding.The purpose of this research is to fully and comprehensively identify the effective indicators in improving the quality of city streets.This research is practical in terms of purpose and in terms of method, using the Delphi technique and the method of structural equations.By using documentary and library methods, opinions and views of experts have been summarized and presented in the form of default indicators.In the first stage, the statistical population of the research was considered to be 20 experts in the field under study.Based on the results of the questionnaire,the initial indicators were analyzed in several stages using the fuzzy Delphi technique, and the final indicators were measured for normality using the Kolmogorov-Smirnov test.In order to finally confirm the indicators extracted from the first stage, confirmatory factor analysis method was used to create a structural equation model. In this section, due to the unknown statistical population, using Cochran's formula, the size of the statistical population was considered to be 384 normal people. Finally, using Friedman's test, the indicators were ranked to determine the effectiveness of each one.The results of the findings are a complete identification of the effective indicators identified in improving the quality of Shahid Beheshti Street in Karaj.

The concept of livability has emerged alongside sustainability as a slogan in public discourse and planning. Planners and policymakers in relation to the creation or preservation of cities mention the concept of livability as a guiding principle for investment and decision-making and shaping the social, economic, physical and biological environment of the city, and livability is considered the standard of living and the general desirability of people living in a settlement like the city. This concept has various dimensions and indicators and is measured by them.The present study was conducted with the aim of providing an analysis of the factors affecting livability in district 8 of Tabriz metropolitan, which by studying the principles and available resources to develop a livability model for the study area. Then, using the opinions of the residents of the area, the model is tested and finally the final model is presented using the second-order confirmatory factor analysis. The results show that 8 main components with 41 variables form the components of the model."Infrastructure quality" with a factor load of 0.88 is the most important dimension and "health facilities" with a load of 0.23 is the least important dimension in establishing livability. Therefore, based on the obtained results, it can be acknowledged that in order to achieve the desired livability and maintain it, the obtained effective components must be comprehensively addressed.

To achieve a sustainable society, it is necessary to recognize the levels of vulnerabilities versus natural risks and root the causes of socio-physical differences. Based on this, recognizing vulnerability and socio-spatial pattern of that is the base of policy making toward reducing vulnerability and increasing resiliency. The objective of this research is to evaluate and rank the levels of socio-physical vulnerability of Ardabil province counties versus earthquake. This research from view of objective is applied and from view of nature and research method is a descriptive - analytic study. The required data for the study has been gathered from the reports of population and housing sections of national census center. To rank the counties in terms of distribution index, TOPSIS and to express the relationship between variables geographical weighted regression (GWR) has been used. The results of research indicate that in terms of social vulnerability Pars Abad County is on the very high zone and Ardabil County is on the very low zone. In contract, in terms of physical vulnerability, Meshkin County is on the very high zone and Ardabil County is on the very low zone. The results of combination of social and physical indexes in TOPSIS model showed that, Ardabil County with score of 0.580 is on the very low zone and Meshkin County with score of 0.411 is on the very high zone of vulnerability. Finally analysis of geographical weighted regression (GWR) indicated that there is direct and significant relationship between population and vulnerability.
