عنوان مقاله [English]
Cities as the most complicated spatial spheres, despite the acceleration of innovation and efforts to develop and excellence, are faced with numerous infrastructure and superstructure challenges. The inclusion of safety and security indexes in spatial planning shows the importance of this area in the process of dynamism and prosperity of spatial areas, including cities. This security and space protection is against damage and disasters that can provide urban threats and crises in urban development processes. The injuries in both human and natural areas can make living in cities more vulnerable to disasters and disrupt the living conditions in these areas. On the other hand, the disasters that have occurred in the cities in recent years and the complexity of their dimensions indicate the increasing vulnerability and dangers of these threats in cities. Therefore, it is necessary to have new attitudes towards threats and strategic measures in this regard. What is, nowadays, considered as a concept for urban planning exposures against human and natural threats is the issue of resilience? Resilience is an approach that evaluates the capacity of tolerance and sustainability of the situation against accidents, threats and challenges. These conditions can be imagined in the form of various components such as social, economic, infrastructural, physical, cultural and environmental dimensions in its macro perspective. The pursuit and necessity of the research topic has shown its importance from two aspects. The first aspect is related to the concept and nature of resilience, due to its importance in analyzing the capacity of tolerance and reliability of arterial infrastructure in the field of urban transport as the communication arteries of the Ahwaz metropolis. On the other hand, the metropolis of Ahwaz is one of the most challenging areas in need of resilience in accidents and crises on the other. This planning process from reducing vulnerability to the strength and reliability of infrastructure flows can be regarded as one of the ineffective defense strategies and even crisis management for disasters and incidents.
The present study has a descriptive-analytic method in terms of target design and methodology. In order to collect descriptive data, the research method has been used in the form of documents in the form of book house studies and reference sources in relation to the subject matter. To analyze the data, a survey was carried out using a questionnaire. The process of collecting and compiling analytical data of the research has been in two stages. Due to the lack of standards and indicators for the purpose of reshaping the arterial transport infrastructure in a targeted Delphi method (consensus or initial confirmation and consensus and final approval). The main source of information layers is also extracted from the map of 1:15000 landuse in the metropolitan area of Ahwaz. The ArcGIS 10-3 software and the similarity model to the Fuzzy Ideal Option (FTOPSIS) has been used for space analysis and spatial mapping of the transport infrastructure in the Ahwaz metropolitan area.
Results and Discussion
Based on the Delphi method and using expert opinions, it has been found that there are 5 explanatory drivers for explaining urban regeneration in the arterial infrastructure. In fact, Delphi-based propagators show that the propagation of texture affects the quality and life of the network and is effective in identifying the damage and network resilience. The pattern of the network design is based on the standardization of the network in terms of its design and its degree of resistance and design stability against threats and risks. The propagator of network consumption is based on the amount of pressure on the network and the identification of high-vulnerability points. Network topology refers to the recognition of the significance and value of the network hierarchy in terms of their resilience, and ultimately the degree of network confinement that refers to the structural aspect of buildings with the width of the passages or arteries, and an important discussion in the resilience of the arteries.
Resilience is a strategic approach to non-operating defense and maintaining sustainability conditions for underlying performance systems and structures. This approach has been considered today in many developed countries to protect the resources and infrastructure of development against natural and humanitarian crises. In the present article, in the present paper, we tried to identify the propellants explaining the fluctuations in urban transportation in the spatial range of the Ahwaz metropolitan area to their spatial analysis and identification of critical points. This study could be an absolute test for future research on the development of these propulsion and assessment of the resilience of arterial infrastructure, including the arterial energy infrastructure in the city.
