Site Selection for Fire Station in Gorgan City Using Geographic Information Systems

Fire fighting stations are one of the elements of public security in the cities. To make them have the supposed role in public security, we should look at different urban facilities in detail and lead the city structure as a whole. Appropriate site selection of fire fighting stations is one of the most important obligations of the city planners, which should be carefully planned and implemented. He better site selection is meant to avoid waste of resources in one hand and better capability of the stations on the other hand. In this research, the best sites for the construction of new stations and moving of those stations with improper location in Gorgan city has been studied. First, conceptual model of the study was defined; then, spatial layers and other information about site selection of the stations collected. In the next session, Analytical Hierarchy Process from the MCE model used to assign weights to spatial layers. This process was done based on the expert's views and pair wise comparison method. After collection of expert views and in order to avoid wrong views, judgment compatibility amounts were calculated. After accepting of CR values, these weights used in future analyses. Fuzzy logic model, using weights of membership functions employed as combination model.Network analysis, one of GIS spatial functions, used to find the best routes from fire stations to affected area and service areas of each station. Based on the analyses of this section and field checks, gave good attitudes in terms of stations functionality. Big overlaps between different stations service areas in some parts and gaps of coverage (where no station covered those areas) in other parts are indicate that security services are not well allocated in the city. Regarding to the locations of current stations, new stations proposed using a moving window on the potential sites map. This last map was prepared using two criteria, available land for new construction and sites where a fire station needed most urgently
