Prioritization Model for Rural Roads network in disaster situation, based on NRI

Natural and Non- Natural disasters have harmful results in various fields of society such as socio- economic. Infrastructure performance have a huge impact in disaster situation and can increase or decrease effects of damage. Considering the unpredictable feature of intensity of disaster, appropriate decisions can reduce failure. In this regards, this paper for the case of Tehran Province Transportation network roads, investigate the important links based on Network Robustness Index (NRI). For that, Tehran intercity networks links, are disconnected in each iteration and OD matrix assigned. Aggregate results on network such as Vehicle hour (VHT) are calculated and used for prioritization. Based on reduced VHT, links are categorized in 4 classes.
