Determination of unsuitability points on the route of Van Gölü-Kapıköy railway line by using GIS and AHP method

Abstract

It is seen that there is a parallelism between the economic power of the countries and the development of the logistics sector of their sustainable competition. According to the free market economy in the Keynesian economic system, the logistics sector has an important function. With the globalization of the world, the logistics sector gains importance and this makes railway logistics gain importance. The development of railways allows the development of the economy. Since it positively affects the cost-benefit analysis of public institutions and organizations and the private sector, the railway route should be chosen in the most appropriate way. In the determination of the route Geographic Information System (GIS) applications are used with the developing technology in recent years. Geographic Information Systems applications, on the other hand, play a major role in collecting data analytically, obtaining results and using the results thanks to computer technologies and software systems. The Analytical Hierarchy Process (AHP) method, which is used together with Geographic Information System (GIS) applications, makes it possible to provide the most appropriate and maximum benefit in line with certain parameters by comparing the alternatives in the decision-making process in the most appropriate way. These parameters considered include slope, aspect, stream, building, small water flow and transportation. Taking these parameters into account, the conditions affecting the railway line were evaluated using the AHP method.
