A multi-criteria decision-making approach of transport intersection toward sustainable urban transport index

Intersections are key causes of traffic problems from a traffic engineering perspective. To determine the options of intersection investment, this study proposes a new framework by performing multicriteria decision-making analysis (MCDA) to determine the manner by which an entire network is affected. A study utilizing comprehensive SAW, TOPSIS, VIKOR, and PROMETHEE techniques is performed and focuses on three main criteria. Additionally, nine subcriteria related to SUTI are considered. This new framework examines the effects of urban mobility levels, which promote effective intersection options. In this regard, MCDA serves as an efficient filter that focuses on the most effective alternatives of an entire network. This decision-making framework is a novel idea for intersections along new corridors, particularly in developing cities, where bypasses are crucial for addressing urban sprawl. A case study in Mukdahan, Thailand, shows that an urban growth rate of 1.856 % affects the effectiveness of intersection selection for road transportation.
