Kentsel Raylı Sistem Yatırımlarında Konjoint Analizi İle Yeni Bir Fizibilite Yaklaşımı Önerisi: Rize Örneği

Abstract

Urban rail investments are known to be one of the most popular solutions used by modern societies in terms of transportation needs and social sustainability. Urban rail systems are costly systems that require more resources. Therefore, investment decisions are taken with feasibility studies. As the feasibility studies in the present day predominantly evaluate the economic aspects of the investments. This attitude delays new investment processes that prevent urban development, so a feasibility approach is needed to fully evaluate the benefit potential of cities. In this study, primarily, feasibility frameworks and investment criteria of public transport systems have been explained. A new feasibility approach which is included using Conjoint Analysis has been developed that can evaluate different benefits of urban transportation investments. The feasibility of the different public transport scenarios pro-duced within the scope of the transportation plan of Rize has evaluated by using the pro-posed feasibility approach. In a medium-sized city, criteria importance has determined for the return on investment 22%, journey time 32%, comfort 11%, pollution 19%, rent in-crease 4%, spatial consumption 12%. Among the criteria evaluated within the framework of the new feasibility method, it has been determined that the rapid bus line is more feasible investment alternative.
