Reliability of Tehran Transportation Network during Earthquake

The great potential of natural and unnatural events in many countries like Iran along with the strategic role of transportation networks in a country's economic, disaster management in Iran's transportation network, especially in its capital, Tehran, has a great importance. Also transportation networks play an important role in various stages of response to disasters, such as evacuation, search and rescue, and reconstruction missions. Hence, special attention must be paid to transportation networks in any disaster management system. Reliability measures are critical in judging the performance of a transportation system and it is very important to evaluate the performance of the network after disaster under the most probable scenarios in planning stages before disaster. In this paper, the causes of degrading link capacities will be discussed and we will propose a new algorithm for computing the reliability of Tehran's transportation network during the occurrence of an earthquake. In other words, we will present an approach for optimizing disaster management of transportation networks. We will verify our claim using simulation by MATLAB. By using the proposed method to compute the reliability, acting in various stages of response to disasters (search, rescue...) by simulation of network's performance would be easier and more secure in planning stages before disaster.
