Optimizing Public Transport Integration Tariffs in Ibu Kota Negara, Indonesia: A Quantitative Approach for Sustainable Urban Mobility

\nThis study introduces an innovative framework for planning integrated tariffs in public transportation, focusing on Ibu Kota Negara, a strategic national region of Indonesia. As Banjarmasin aims to establish a modern, inclusive, and affordable transportation network. This study aims to determine fleet needs, integration rates based on vehicle operational cost calculations, ability to pay integration rates and an effective subsidy scheme for Trans Banjarbakula and Trans Banjarmasin. A quantitative approach is applied in this study through analysis of fleet needs, determining vehicle operational costs, the stated preference method and developing a mechanism for providing subsidies to encourage accelerated integration of bus operations. The results stated that fleet needs were identified as having the highest value in trip requirements during the morning peak based on the value of vehicle operational costs, ability to pay and referring to the provision of subsidies by the government to adjust integrated tariffs based on the community’s ability to pay with planned scenario tariffs. A key novelty of this research lies in its proposed socialization initiatives that promote integrated tariff education, facilitating the transition to a smart cardbased payment system. This model promises substantial benefits for users and policymakers, laying a foundation for sustainable, cohesive urban transit solutions in national urban centers.\n
