| Abstract | ||
| Baghdad City suffers from severe traffic congestion due to the rapid urban expansion and travel demand growth. Based on many studies, urban rail transit was proposed by experts and the related transit agencies as an optimal solution to solve this problem. Accordingly, Baghdad metro route selection based on multi-criteria was proposed to be studied, evaluated and searched in the present research. The methodology utilizes a GIS to prepare and analysis data. Data was analyzed using a two-stage multiple-criteria decision making (MCDM) model which includes Analytical Hierarchal Process (AHP) and TOPSIS methods. Moreover, Geographic Information System (GIS) was used to explore the various route alternatives. To select the best alternative, all alternatives were evaluated against the selected criteria. The weighting system is not only based on expert’s opinions but also includes a set of measures based on real data. Based to the outcomes of the present study, alternative route number 1 can be recognized to be the optimal route in the year 2014, and alternative route 2 is recommended to be adopted to meet the high travel demand requirement in the year 2035. | ||
