Application of analytical hierarchy process and the traffic micro-simulation model on highway interchange selection: Case study of highway no.12 and rural road no. morhor 4040

Abstract

Department of Rural Roads has been constructing rural road no. morhor 4040 that can support the expansion of the city of Mukdahan. However, from the results of the analysis of traffic volumes and future service levels of the project road junctions, Intersection with Highway no.12 reflects the potential for future traffic congestion after opening. This study applied the Analytical Hierarchy Process (AHP) together with the traffic micro-simulation model to evaluate the multiplier and score of the factors used in the interchange selection. The result presents the traffic micro-simulation evaluation result that were used attribute to determine multiplier of all factor which determine appropriable interchange. Alternative 3 is the best alternative that construction overpass along Highway no.12 with roundabout (Score = 99.91%). This approach is an alternative option for the interchange selection for agencies whose primary mission of road study and design in the future.
