Abstract: Research on optimization of highway alignment has been quite intensive in two past decades. Determine the best candidate of highway alignment is one of the most complex of highway design stages because the effect of various parameters with different impacts. Hence, in the present study, a multi-criteria analysis methodology is proposed to determine the best highway candidate with the special focus on the cost and safety criteria. The multi-criteria analysis methodology is based upon the analytical hierarchy process technique which systematically transforms the performed calculations for each criterion into a series of simple pairwise comparisons and then determines the weight of each criterion. Provided methodology in current research is not limited to cost and safety criteria and can be upgraded to other criteria. This methodology is carried out for a case study region in western north of Iran and therefore cost and safety criteria are obtained for case study condition.
