Investigating and Assessing the Vulnerability of Transportation Networks and Analyzing its Interaction with Urban Airports

What in this research it has been addressd vulnerability  review and assessment transportion networks  and its interaction analysis Emphasis on urban air ports against man made threats and proposals to reduce vulnerability based on the principles and foundations of passive defense is. Airports by providing  fast shipping platform and passenger and with high capacity between regions with a long distance to the comprehensive development of countries and even the provinces help a lot so that it as one of the symbols of development Civilian airports are currently considered as one of the vital and valuable assets in any country that is considered as one of the air borders, and will be very important, so that taking measures to reduce their vulnerability to threats is necessary and unavoidable, so that The slightest disturbance in its functioning or damage to its body causes huge material and moral damages. The current research is an applied research, and it is in the category of descriptive-analytical research, the required information has been collected using documentary methods, including library documents, observations and field. For this purpose, a number of 32 experts were chosen as experts and FEMA method was used for risk analysis and the information was analyzed using Expert choice software and AHP technique. The findings of the research show that the assets of city airports in different sectors are seriously vulnerable to military attacks and man-made terrorist acts Of course, according to the type, nature and function of each of the infrastructure elements, the degree and level of vulnerability is different And it is possible to explain the factors of increasing vulnerability and the ways to reduce it for each key asset, with the aim of ensuring the continuity of activity and maintaining the airport infrastructure and protecting human lives.
