Evaluation of Khorasan Razavi railway stations using TOPSIS in GIS

Railway as a transportation system is an important issue because of some advantages such as crowed of people, transportability, environmental impacts, energy saving and tourism attraction. In this issue determining suitable rail stations is necessity because of noticeable effects on economic, social, political and cultural applications. So the aim of this paper is to survey the condition of rail stations in Khorasan Razavi case study to estimate locations and improve existed positions for development. For this purpose, geospatial information system (GIS) as a flexible framework is used to program, manage and decide on spatial data for specifying best locations. Continually the related data included crowding center, industrial and commercial infrastructures are controlled and prepared to enter GIS an MCDM (TOPSIS & AHP) models. The results of the implementation show that Marzdaran is the worst station by rank of 22 and the best stations are located near big cities. In addition, evaluation of AHP and TOPSIS presents that Neghab station has the highest modification among all others.
