Analysis of transportation criteria in order to decrease vulnerability arising from earthquakes in city passages (ANP-SWOT)(Case study: central texture of Sanandaj)

In order to decrease the vulnerability, urban planning is in need of recognizing the vulnerability of every physical elements of the city. In this case, evaluation and analysis of the transportation criterion in order to decrease the vulnerability of the communication network and especially city passages, as a physical element of the city, is highly important. This research, deals with the analysis of the transportation criteria by using analytical network process (ANP-SWOT) with the applied analytical method. The objective of this research is to analyze and evaluate the transportation elements in order to decrease the vulnerabilities arising from earthquake, and to recognize and separate the effective factors on vulnerability in the city passages network of Sanandaj. The transportation criteria that are used in this research are, city land use, materials and quality of buildings, the distance of the passages network from fault, passages hierarchy, optimizing the capacity of passages, remoteness and proximity of passages to the medical centers. The final results indicate that the ranked one criterion of the passages hierarchy has the most importance and the material and the quality of the buildings with the priority six has the least significance.
