Due to complex components of a trip, previous research is hard to practically measure transport accessibility and assess the quality of public transit services. However, better investigation of public transit quality highlights the importance of the accessibility for environmental perspectives, health problems, and equity issues. This study aims to assess the quality and equity of public transit services of Sydney, Australia using two measurements. Since the value of private car use also influences individual’s choice of transport modes for a trip, the first measurement is relative accessibility, a comparison of accessibility between multiple public transport modes and private car use at peak time on a typical weekday. The second measurement is service frequency of public transport modes. These two measurements contribute to the knowledge of assessment of transit quality by considering multi-public transport modes during one trip, congestion, and frequency. Results show that 89.10% of populations have medium-very high relative accessibility to CBD. After the integration of service frequency, only 29.75% of populations enjoy above average public transit services. 3.6% of populations have adequate service level in terms of public transit. In this study, the utilization of Google Maps application programming interfaces makes the accurate estimation of accessibility feasible. Meanwhile, this study provides a realistic picture of Sydney public transit services by taking into account service frequency of multiple public transport modes. It will help urban planners and policy makers to improve the quality of public transport facilities for sustainable development.
