So that, the highest vulnerability based on network access roads and open space, related to region ۸, and the least vulnerability related to ۱ area and ۶ is urban. The result to reduce the vulnerability in urban areas of Shiraz, based on the criterion of proximity sensitive centers, zones ۴ and ۱ in priority scheduling are.
