Metro stations site selection in Karbala city using (GIS)

Karbala city suffers from a range of traffic congestion problems due to increased travel demand, population growth, and limited transportation infrastructure. A metro system has been proposed as a solution for this problem, and this paper thus aims to determine the best locations for stations based on multiple criteria, to serve largest volume of passengers and to connect vital places, and highly populated areas. This analysis is done using geographic information systems (GIS) as a powerful tool for spatial analysis. The Analytic Hierarchal Process (AHP) was used in weighting the criteria and a degree of importance selected for each one. The results showed that 31 station sites could be selected as the best sites for metro stations.
