The concept of accessibility, integral to transportation systems and planning projects, continues to lack widespread consensus regarding its definition. An efficient public transportation system plays a significant role in providing improved mobility to its users by enabling a sustainable and accessible urban environment. This study aims to understand how accessible the healthcare facilities to the population across the study area using this sustainable mode. The spatial distribution of bus stops and hospitals is the land use components, whereas walking time, proximity to bus stop and travel distance, speed and frequency of buses are the transport components considered in this study. Modified two-stage floating catchment area method and hierarchical floating catchment area method are compared against a proposed novel method to assess the accessibility of healthcare facilities in the study area at an aggregate level. The accessibility is classified into three levels and analyzed with respect to the demand for the facilities in terms of population and frequency of transportation services. This will yield better understanding of healthcare spatial inequity and demonstrate areas of key intervention for planners and policy makers.
