Evaluating the performance of transportation networks in case of disaster in suburban areas (Case Study: suburban areas at north of the city of Tabriz)

transportation networks is one of the main factors in crisis management there. In case of inefficient transportation networks during unexpected events, they will cause major problems in providing assistance rather than addressing the problems and facilitating the transportation. There exists a direct relationship between the time to reach to the place of the event and the loss of life. This actually requires efficient transportation networks. The other discussion is that in cities, especially cities in less developed countries, all over the city are not equally vulnerable to disasters. Compared to other parts of the city, due to their specific characteristics, suburban areas are more vulnerable to disasters. Human populations living in these areas due to the large volume of strong and irrefutable scientific and practical importance and necessity of study and action in relation to these areas. The main objective of this research is to find out the coefficient of performance of transportation networks in suburban areas at north part of Tabriz (study area of this research) at the time of crisis. The research method in the study is descriptive, analytic and field study. To achieve the research objectives of the Inversion Hierarchical Weight Process model is used. Thirteen indicator in this model that could be effective in network vulnerabilities was selected road networks and Were analyzed. Final results showed that out of the 16 networks in suburban areas of north part of the city of Tabriz, two transportation roads are not vulnerable
