Earthquake is one of disasters, which causes many problems in economic and society in Iran. With respect to the harmful effects of earthquakes on the human societies, disaster management is very important problem. Then, GIS as a science and technology for managing, representing, retrieving, saving and modeling of spatial and non-spatial data is efficient tool for decision making and planning for earthquake disaster management.
When earthquake is happened, roads are presented as important criteria for rescue activation. Their obstruction is one of the important problems for rescue in the earthquake situation. If we have ability to identify high danger obstructed roads, we can decide about the resistance of buildings, widening roads and assigning authorization for construction.
In this study we try to design a new model for road obstruction with respect to buildings heights, roads width and materials, which used in the closet structures. At first, we define problem structure. Then, we introduce road obstruction model that designed. Finally, we implement this model on the Farahzad (which is a part of Tehran) case study and we will discuss about results.
