Developing Optimal Zones for Urban Parking Spaces by Arc GIS and AHP

Nowadays, finding a place for vehicle's parking space has become a big challenge especially, in downtown of metropolises. Parking places are as one of main part of the modern urban transportation system, having the crucial role of removing static traffic from streets, which can cause to reduce streets' parking spots, improve vehicles movement and increase the width of streets indirectly. Allocations of public parking spaces have been done in traditional way by visiting the location until few years ago without considering all effective parameters in allocation of public parking spots. The only parameter that has been considered, being the price of land. Geographic Information System (GIS) takes into account a suitable system for specifying optimum location to develop the public parking space. Using the GIS has the merit of increasing accuracy in comparison with the traditional method. This research presents proper method for locating of public parking place by consideration all effective parameters and by using GIS. The effective parameters have been weighed by AHP method. Then these parameters have been combined by fuzzy algebraic sum. This method has been used for locating suitable parking spots in region1 of Tehran as the case study.
