Globally, millions of individuals access services and opportunities on a daily basis using different modes of motorized and non-motorized transportation. However, in the global south, the role of public transport in providing access to services is relatively under-researched due to non-functional public transport services and poor infrastructure. This paper uses data from the Greater Accra Metropolitan Area (GAMA) to empirically contribute to the discourse on how public transport availability varies across different residential locations and assess if there is equitable access to Public Transport Infrastructure and Services (PTIS) across urban and peri-urban areas. A household questionnaire survey was designed to collect data on public transport access based on socioeconomic, socio-cultural, personal preferences/experiences and residential location in the Greater Accra Metropolitan Area (GAMA). A sample size of 1340 respondents, consisting of males and females between the ages of 18 and 70 residing in GAMA, was achieved. The paper also used data from the public and open databases. The Three-Step Floating Catchment Area (3SFCA) and geospatial methods were used to estimate spatial accessibility.
