Highway Route Planning via Least Cost Path Algorithm and Multi Criteria Decision Analysis Integration, a Comparison of AHP, TOPSIS and VIKOR

Highways are one of the main structures cities in field economic, social, and environmental facilities that connect cities, regions, people each other. Determining suitable highway routes includes difficult complex processes due to construction costs. Additionally, priorities, expectations, constraints for parameters must be considered together provide efficient solutions requirements. Multi Criteria Decision Analysis (MCDA) techniques such as Analytical Hierarchy Process (AHP), Ideal Solution Similarity Selection Ranking Technique (TOPSIS), Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) Least Cost Path Algorithm (LCPA) with Geographical Information Systems (GIS) combination most way overcome these complexities. In this study, slope, aspect, geology, elevation, distances roads, settlements, water bodies, fault lines, buildings, natural disasters, protected sites, population, land use were selected determine areas route. The AHP, TOPSIS, VIKOR methods applied calculate cost surfaces least paths generation LCPA, generated three compared. As a result comparisons route was considering topographical statistics all consistent other current road.
