Abstract

The practice of considering transportation choices involves several key components depending upon the factors, weights, and decision-making techniques. The current study used Multi-Criteria Decision Analysis (MCDA) tools in considering intersection improvements alongside traffic microscopic model. The findings revealed the following: (1) the level of complexity of the decision-making tools affects the prioritization of options and (2) the integration of decision-making models confirms the most suitable approach. In the case study of the Kalasin Intersection located in Maha Sarakham Province, the results of the analyses from SAW, WASPAS (λ = 0.5), TOPSIS, VIKOR (v = 0.5), and PROMETHEE (ϕ+(i)) converged towards Alternative 3.3: The new roundabouts at both intersections and VA traffic signal with a bypass left lane at the Kalasin intersection as the best option. The framework of this research describes new approaches to integrating the five MCDA tools, and exploring the intersection improvement options. This presentation of new decision-making frameworks illustrates the progress that is being made in the dimensions of transportation engineering decision-making with regard to intersection improvement prioritization.
