Abstract:
Fire fighting station are one of the elements of public security in the
city. to make them have the supposed role in public security; we should look at different
urban facilities in detail and lend the city structure as a whole.
Appropriate site selection of firefighting stations is one of the most important
obligations of the city planners, which should be carefully planned and implemented.
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, best sites for the construction of new stations and moving of
those stations with improper location in Tehran 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 used
to assign weights to spatial layers. This process was done based on the expert's views
and pair wise compaction 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.
Network analysis, one of GIS spatial functions, used to find best routes from
fire stations to affected area and service area of each station. Based on the analyses of
this section and field checks, gave good attitude in terms of stations functionality.
Regarding to the locations of existing stations, new stations proposed using a moving
widow on the potential sites map.
