Analysis and evaluation of effective variables on improving the urban road network resilience in the natural environmentMan-made (case study: five areas of the eastern part of Tehran)

The communication network network is one of the most important structural elements of the city's physical architecture. It is a standard measure for measuring the ability of the urban system to absorb changes and re-invent the changes resulting from disruptions and capacity building. The purpose of the research is to analyze and evaluate the variables that are effective in promoting resilience, identifying and identifying the factors affecting the vulnerability and reducing the losses and damages caused by the crisis in the natural and man-made construction of the earthquake network in the eastern region of Tehran. The method of this research is applied in terms of purpose and based on descriptive-analytical method. The data were obtained using library resources as well as surveying and field studies. Data analysis uses the AHP model using GIS. The results show that: By applying seven criteria in two classes Considering the population density and blockage of the roads in area 13, the most vulnerable streets are Imam Ali and Basij highways and the axes leading to them, based on the travel pattern of residents of the northern part of the 4th and 8th zone, with emphasis on Hemmat and Imam Ali highways Blocking, passageways, according to the degree of enclosure associated with areas 14,13 and 15, identification of social capacities of residents Towards area 15, the physical exhaustion of areas 14,13 and 15, and the building density component of areas 8 and 13, will have the highest vulnerability during accidents and crises.
