A sidewalk is a part of the urban space where pedestrian movement is prioritized and vehicle movement is eliminated in all or part of it. In addition to providing access, the sidewalk creates a lively, safe and comfortable space for the presence of different social groups, social interactions and optional activities. The aim of the current research is to present a model of sidewalk construction in Khorramabad city with a theoretical-applied approach based on modeling and software studies. To achieve the objectives of the research, 4 categories of indicators are used through the minimum spanning tree algorithm in the standard Matlab 2016 software environment. For the spatial analysis of the indicators, the network analysis process has been used in the ArcGIS software environment. The results showed that 29.43% of the area of Khorramabad is in a completely suitable condition for the construction of sidewalk. Spatial analysis of Khorramabad city shows that five optimal routes can be achieved for the development of sidewalks in the city. These routes are in accordance with the theoretical models obtained from the research, including: socio-economic, physical-spatial, traffic and access criteria. The best routes for pedestrian construction are: 22 Bahman Square, Velayat Boulevard, 60 Meter Boulevard, and Sharq Boulevard towards Koi Enghelab.

Assessing and measuring the resilience of rural communities is one of the most important tools in determining the sustainability of rural settlements when environmental hazards occur. In the Dehdez section, there are numerous rural and nomadic settlements and are prone to many environmental hazards throughout the year. Rural settlements and their inhabitants do not have adequate resilience in various dimensions in the face of environmental hazards. The purpose of this study is to explain the resilience pattern of rural settlements in Dehdez section of Izeh county. In the theoretical foundations section, various methods are explained based on previous research and theories, and then the conceptual model is presented. The study method is descriptive-analytical. The statistical population under study includes all heads of households in rural areas above 20 households with 3003 people. The sample size was 341 according to Cochran's formula. The research tool includes a questionnaire with 60 questions. The data were analyzed using SPSS 22 and AMOS software and the Kolmogorov-Smirnov test, confirmatory factor analysis, and structural equations. The results indicate that each of the coefficients of impact of environmental-natural, social and economic indicators, institutional-managerial and physical-spatial on the resilience of rural settlements located in the research area are 0.73, 0.40, 0.19, and 0.25 respectively. In the resulting resilience pattern of the present study, the rural settlements of Dehdez district are generally in good condition in terms of resilience. This pattern places more weight on the natural index than on the human. As a result, in terms of natural-environmental index and adaptation to environmental conditions, villages have the highest resilience and in the institutional-management index, which requires organizational, institutional and human actions and efficiency, have the lowest resilience.
