The assessment of urban road network vulnerability on earthquake against with crisis management approach; Case study: region1/Tabriz
Abstract


The urban road network is one of the main components of the city’s lifelines that especially after crisis play significant role including the rescue operation, evacuation of the wounded. So the analyzing of the urban road network besides planning for reducing these harms, are inevitable. The present study was performed with “descriptiveanalytical” method to assess the seismic vulnerability of the urban road networks in the zone1 of Tabriz with crisis management approach. In order to evaluate urban road networks vulnerability of region 1 of Tabriz, 3 criteria of density, level of inclusion and building features were employed. In this regard, the density criterion includes both sub criteria of residential density and construction density. In addition, the criterion of the building features includes 5 sub criteria such as: The building date, building quality, land use type, occupancy levels and types of materials which each of these sub-criteria are divided into other sub-criteria that these sub-criteria were weighted using Delphi method. Ultimately, after evaluation of roads vulnerability in terms of each criterion, the layers were overlaid using multi criteria evaluation. The ultimate results show that, the roads network vulnerability (excluding the region 1) is higher than the average, high and very high. The vulnerability of the road networks are observed mostly in informal settlements area that should be noticed in planning. Crisis management, Vulnerability, Urban road network, Tabriz
