Evaluation of medical- relief centers along with the design of the geometric network of routes to determine the nearest center and the best path to reach the site of the accident using GIS
Abstract:   (238 Views)
Background: Historical textures have become one of the most vulnerable urban textures during the crisis due to the severe physical decay, structural instability, and lack of proper accessibility; therefore, site selection of the crisis management bases is essential for these textures. In this research, site selection of crisis management bases in the historical texture of Shiraz city is investigated.
Method: In this applied and descriptive-analytical research, the combination of GIS and FAHP model, the paired comparison of the criteria, the determination of the weight of the criteria, and the provision of the information layers maps has been used for site selection of the bases. In addition, Gogos and Boucher's method have been used in order to calculate the consistency rate in the judgments.
Findings: Four criteria were identified as the effective factors in site selection of crisis management bases including physical desirability (grain, stability, land use), accessibility (closeness, straightness, gravity, betweenness and reach/access), adjacency to compatible land uses (green space, health centers, police stations, fire stations) and finally non-adjacency with incompatible land uses (hazardous installations, high-rise buildings). Physical desirability and adjacency with incompatible land uses criteria with the weight of 0/356; then, accessibility measures with the weight of 0/195 and adjacency to compatible land uses with the weight of 0/114 had respectively the most importance in the site selection of the crises management bases.
Conclusions: The results showed that because of the lack of desirable accessibility, it is appropriate to consider the accessibility criteria for the site selection of the crisis management bases in the historical textures. After overlaying the maps of the information layers, two options such as the library of Holy Shrine of Shahecheragh and Pars Museum were introduced as the location of crisis management bases in the historical texture of Shiraz.
