Metro Manila is the main metropolis of the Philippines—the center of its society, government, and the private sector. Thus, many trips are generated within Metro Manila and between its surrounding provinces. Without alternatives, these trips are dominated by public transportation, yet private cars occupy more spaces in road infrastructure. This study aims to develop a general model to define public transport choice in Metro Manila through Logistic (LOGIT) Regression. The study results show that Household Income is a good predictor of the trip makers' mode choice between Public Transportation and Private Transportation in Metro Manila. As the total income of the household increases, there is a tendency to choose private transportation as the trip mode. The study findings will help inform decisionmakers in their policy directions to improve the public transportation system in Metro Manila as a sustainable mode choice.
