We use a high-frequency administrative dataset containing trip-level public transport usage information in millions of smart transit cards of Singaporean residents to study the behavior of public transport commuters. The results show significant heterogeneity in the public transport mode choice by different individuals, and also dependence of the public transport mode choices on trip purposes. We find that travel cost affects the public transport mode choices of senior citizens, students, and children; whereas, travel time and travel time reliability affects the mode choice of public transport of adult commuters, and also mostly for the work-related trips by the adult commuters. The results have important implications for policy makers in formulating action plans for the public transport system. Lessons from strategies implemented by Singapore’s government that have improved efficiency and reliability of the public transport system are discussed..
