Issues on public transportation have become indispensable ingredients of Metro Manila's transportation struggle. Issues concerning car ownership and the existence of new public High-Occupancy Vehicle (HOV) Tamaraw FX were seen alarming. So far, considerable studies on the impact of the MRT on the Tamaraw FX riders have not yet been undertaken. This paper therefore attempts to clarify the significant factors affecting the Tamaraw FX passengers' mode switching behavior considering the post - MRT 3. The study hopes to understand the Tamaraw FX riders' propensity to switch to the rail-based mass transit system. Hypothetical scenarios of variable travel time and cost is presented to the passengers to determine the variations of their switching decisions. A mode-switching model (Logit Modeling) was employed in the analysis. The study also investigates the potential role of Tamaraw FX when the MRT is in full operation. This is in view of arriving at operational policy recommendations to facilitate the government's plight in solving the issues on urban mobility in Metro Manila and to fill the gap between the public transportation modes. The results of the study show that the combined household income, total number of trip transfers and total travel cost significantly affect the passengers' mode switching behavior. The same variables were found influential in the passengers' decision to use FX as an access mode to the MRT station.
