Using Multi Attribute Utility Theory and Rank Order Centroid Methods: A Case Study of Phuket City to Patong Beach Corridor

Abstract

The purpose of this study is to determine the most suitable light transit system for Phuket Province using Multi Attribute Utility Theory (MAUT) and Rank Order Centroid (ROC) methods using Phuket City to Patong Beach Corridor as a case study. Respondents are classified into four sectors including designers, social sector, service providers and service users. Each sector rates score for each alternative and prioritizes decision factors based on their criteria. The results show that each group selects the most appropriate system and ranks the most important factors as follows: designers choose the Tram system based on construction difficulty, social sectors choose Bus Rapid Transit (BRT) system based on environmental impact, service providers choose Electric Vehicle Bus (EV Bus) system based on project cost, and service users choose Automated Rapid Transit (ART) system based on accessibility , respectively. If all respondents are equally important, the most suitable light transit system for Phuket is ranked as follows: ART (1st), Surface BRT (2nd), Tram (3rd), and EV Bus (4th). The analysis results provide guidance for selecting a suitable light transit system for Phuket Town to Patong Beach, considering all stakeholders' concerns.
