Rail systems constitute the body of the public transport in cities. Suburban, tramway, light rail systems, metro and monorail systems are urban rail systems and participate in urban public transportation. In this context, large investments are made in railway systems in urban areas and urban transport is being tried to be improved.
Istanbul Metropolitan Municipality, which realizes its investments with a service concept that can be an example to the world states, also makes and plans big investments in the field of rail systems. Managers aim to increase the quality of life of Istanbul by avoiding the traffic problem brought by the increasing population and urbanization in Istanbul with short, medium and long-term rail system plans. However, it is not possible to make every project. Projects that provide the most benefits within certain constraints and criteria such as the budget should be prioritized or selected. Multicriteria decision making techniques are widely used for project selection. In this context, in this study, the planned rail projects in Istanbul are selected under the different budget scenarios using the analytic hierarchy process and the goal programming method in an integrated manner.
