Zusammenfassung: | Research on highway alignment optimization has been quite intensive over the last two decades. Determining the best candidate for highway alignment is one of the most complex highway design stages due to the different effects of various parameters. Hence, in the present study, Analytic Hierarchy Process technique is proposed to determine the best highway candidate with special focus on the cost and safety criteria. The methodology presented in the current research is not limited to the cost and safety criteria but can be extended to other criteria. This methodology is implemented on a case study region in north-western Iran, and therefore the cost and safety criteria are obtained for the case study conditions. The final result of the current paper indicates that the optimal highway candidate obtained with the proposed methodology can simultaneously meet all relative parameters in highway alignment optimization based on their impact. Keywords: Analytic Hierarchy Process; cost category; safety parameter; the best highway candidate Istrazivanje o optimizaciji trase drzavne ceste postalo je vrlo intenzivno u zadnja dva desetljeca. Odredivanje najboljeg kandidata za trasu ceste jedan je od najslozenijih stadija u projektiranju ceste zbog razlicitih ucinaka raznih parametara. Stoga se u ovom istrazivanju predlaze metoda analitickog hijerarhijskog procesa u svrhu odredivanja najboljeg kandidata za cestu posebno usmjerena na kriterije troskova i sigurnosti. Metodologija predlozena u ovom istrazivanju nije ogranicena na kriterije troskova i sigurnosti vec se moze prosiriti i na ostale kriterije. Ta je metodologija primijenjena na istrazivano podrucje na sjeverozapadu Irana te su kriteriji troskova i sigurnosti dobiveni za uvjete analiziranog slucaja. Konacni rezultat pokazuje da optimalni kandidat za cestu dobiven predlozenom metodologijom moze simultano zadovoljiti sve relevantne parametre u optimizaciji trase drzavne ceste na temelju njihovog utjecaja. Kljucnerijeci: analiticki hijerarhijski proces; najbolji kandidat za drzavnu cestu; parametar sigurnosti; troskovna kategorija |
