Abstract

Public transportation plays a significant role in the lives of human societies, influencing essential factors such as economic, social, cultural, and environmental aspects of the community. The bus rapid transit (BRT) system, a form of public transportation, takes part of the traffic solution in urban transportation networks. The process of selecting and ranking appropriate strategies to address the challenges and obstacles for the effective operation and implementation of the bus rapid transit (BRT) system is a significant requirement. Recent research has widely discussed the issue, but such assessments have remained limited in Viet Nam, Ho Chi Minh city where there are many challenges in improving the traffic solution and analyzing the direction of proposal for the implementation of BRT system in Vo Van Kiet - Mai Chi Tho boulevards. As a result, to facilitate the assessment process, this study addresses the research gap by identifying the most significant obstacles to the implementation and operation of the BRT system. Additionally, it recommends the most effective approach to overcoming these challenges. To tackle this problem, simulation with Arena 14 represented an realistic system operation of Bus 39 and Bus D4, then a BRT optimization model with OptQuest for Arena software has been created to minimize multiple objectives including total of passenger waiting time and vehicle energy consumption. Firstly, the study simulated reality scenarios using Arena 14 software, and analysis of variable by adjusting buses to the current bus system of Bus 39 and Bus D4, as well as accelerating the BRT buses, are then constructed to solve the multiple objectives. Additionally, these scenarios are ii evaluated and ranked with Multiple criteria decison-making (MCDM) integrating Fuzzy and AHP. Finally, the most effective approach is compared to the results obtained from the optimization of each response variable on a unified BRT line. The results indicate the suggested approach ensuring the BRT system is executed and operated successfully enough to tackle real-life issues. The methodology presented in this study can be highly beneficial in aiding public transportation operators to effectively establish and manage a Bus Rapid Transit (BRT) system.
