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.

Risk zoning is an important approach to the pre-crisis management process, which assists planners and managers to be prepared for reducing vulnerability. The key issue is the selection of vulnerability criteria and how these criteria are combined. It is also important to select the suitable model that can best illustrate the vulnerability. The city of Tabriz, from the viewpoint of size, industrial, economic, social and cultural conditions, is considered as the metropolis of northwest of the country, however, its proximity to a large and active fault has created an unfavorable condition for the city. In the present paper, using IDRISI and ArcGIS software, 15 selected criteria have been analyzed. Also, a combination of Fuzzy and AHP logic models were applied to analysis of vulnerability of urban areas and their population. The results showed that regions 10 and 1 of city municipality have the worst possible conditions respectively. Conformation of the results to the existing situation indicates the high accuracy of the chosen model for zoning the earthquake hazard.
