Spatial analysis and site selection fire stations in Isfahan city by using inversion hierarchical weight process (IHWP)

One of the modern cities problems is the lack of adequate site selection of urban activities that faced them with challenges. However, fire stations as one of the urban services activities are not excluded from this. Due to rapid population growth and illegal growth of cities, the city's safety system needs to be improved to provide adequate coverage for the entire city. Adequate site selection of fire stations is very important in rapid and timely access of firefighting vehicles to the scene of the incident and lowers the severity of damages. On the other hand, the timely arrival of firefighting trucks at the site of the accident requires the appropriate distribution of fire stations.
In this descriptive-analytic research, the required information is obtained through field observation, interview, studying the completed plans in relation to Isfahan city and the city's 1/2000 map.
Findings: The results indicated that existing fire stations only covered 52.03 percent of active urban spaces at standard time; it is necessary to find new site selection in order to promote fair access for citizens and to improve spatial distribution pattern of fire stations due to the standards.
According to the research findings, suitable locations for redistribution of existing stations and construction of new fire stations have been proposed by collecting effective data in form of information layers such as communication network, population density of areas and areas susceptible to accidents, land use, etc. and using GIS and Inversion Hierarchical Weight Process (IHWP).
