Abstract :
Nowadays with increasing population growth and the tendency of large cities to accept immigrants, the lack of public parking spaces in these cities is obvious. The inclusion of public parking spaces in developing countries is one of the significant issues in city’s transportation system. Ardabil is one of the centers of the country's newly-established provinces that due to deprivation and the lack of necessary substructures in transportation section, proportional to the increase of number of the automobiles and it's narrow streets (that according to some people they were built 60 years ago for carriages to cross ), it hasn't changed into a megacity yet and is the first city which forms the traffic point of view has outrun all the other megacities. This city which has old and inefficient structures frequently lacks methodical maps and the essential space to park the vehicles especially during rush hours. These factors along with the characteristics of being a tourism site necessitate building of parking lots for removing and controlling the traffic in this city. Therefore, in this research to prevent the traffic jam inside the city, the Analysis of Hierarchical Procedures (AHP) and Weight Co-covering Index were used to launch locating of parking lots in Ardabil's district 2. Attending the studies that have been done in the field of outer layer in AHP Procedure and Weight Co-covering index, we observe that the efficiency of The Analysis of Hierarchical Procedure (AHP) is remarkably important. Since, this procedure is flexible, we can launch producing the maps with low risk to high risk. While, in Weight Co-covering Index the layer can be divided to 3 or 4 unsuitable categories to suitable ones, outer layer produced by this procedure conforms to the layer produced by AHP with average risk. Most of the selected sites for building parking lots by these two procedures have been located in barren lands.
