Spatial Analysis and Optimization of Urban Fuel Planning(CNG), Case Study of West Regions of Tehran

The purpose of this study was to determine the appropriate locations of fuel supply stations (CNG) according to the existing criteria in the western areas of Tehran. In this regard, using the GIS, a map of effective parameters in locating gas refueling stations, such as: population density, passages and access, land slope, compatible and incompatible uses was prepared .. Using the Analytic Hierarchy Process (AHP) model Parallel comparisons between criteria were performed and the importance and weight of each criterion were determined using Expert Choice software. The results of weighing the criteria showed that the criteria of fire, access and population density had the greatest impact on creating suitable locations for gas refueling, respectively, and the development of gas stations in the western part of Tehran Municipality has not been done based on population needs of different areas. The output map obtained by spatial analysis and AHP showed that among the available stations, about 29% of them are located in areas with good potential and 71% of places are in places with medium potential and no places are located in places with unsuitable  potential. Also, 32.53% of the areas have suitable potential, 43.76% have medium potential and 23.7% have inappropriate potential for construction of refueling station.
