APPLICATION OF MULTI-CRITERIA ANALYSIS FOR RAIL ALIGNMENT RELOCATION: A CASE STUDY OF JAGODINA

Abstract

The process of rail alignment planning and design in infrastructure projects is often complex and influenced by numerous, sometimes conflicting, factors. As part of the preliminary design (PD) for the Belgrade–Niš railway modernization project, intended for speeds up to 200 km/h, the initial alignment was designed to remain within the existing corridor, with the station retaining its current location. However, following concerns raised by a group of local citizens regarding the alignment passing through the city, the possibility of relocating the railway alignment and station in the Jagodina area was additionally analysed. To ensure a balanced and informed decision-making process, stakeholder input was included in the definition and weighting of criteria used to evaluate the options. The main objective was to identify the optimal alignment and station location that integrates technical and technological feasibility, economic viability, and environmental and social considerations. Three alternative variants, along with the PD solution, were assessed using Multi-Criteria Analysis (MCA) methods, PROMETHEE and TOPSIS, with accompanying sensitivity analysis to test the robustness of outcomes. This case demonstrates the practical value of MCA tools in navigating complex planning decisions and highlights the importance of early engagement with affected communities.
