Tehran Suburban passenger terminals Locating using multi-criterion optimization model

Abstract
Suburban passenger terminals locating processes used in most cities indicates that methods used as non-scientific and based only on expert opinion. In this paper, a mathematical model which has been developed by the authors of this paper was applied to locate suburban terminals in Tehran. First, the most important criterias in locating terminals were identified by interviewing the experts and specialists and also by completing questionnaires. To excequte this model) which is a large scale programme (, the Branch and Bank method was used on TransCAD software.
Based on the results of implementing this model, four places in Tehran were identified in order to build the terminals and analesis of technical and economic evaluation of the results have been carried out shows positive results. In this paper a comparison between the results of the proposed model in this study and the existed model in the master plan of transport and traffic of Tehran was made. The model of master plan suggests 14 locations to construct the terminal, while, proposed our model showes that construction of more than 4 terminals may not be economically justify. Considering the significant differences in functional status, the proposed method in this study clearly varifies as an effective and efficient method to locate terminals.
