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. The study found a significantly high disparity in accessibility to public transport in the Greater Accra Metropolitan Area (GAMA). There is also significant spatial inequality in the level of access to Public Transport Infrastructure and Services (PTIS) in GAMA. The study revealed that the planning and provisioning of public transport infrastructure in GAMA has left areas with inequitable access to transport services. There is the need for increased investment in public transport infrastructure in EAs where Public Transport Infrastructure and Services (PTIS) were found to be very low or low in GAMA.
在全球范围内，数百万人每天使用不同的机动和非机动交通方式来获取服务和机会。然而，在全球南方，由于公共交通服务功能失调和基础设施差，公共交通在提供服务获取方面的作用相对缺乏研究。本文使用来自大阿克拉都会区（GAMA）的数据，以实证方式为关于公共交通可用性如何在不同居住地点变化的讨论做出贡献，并评估在城市和城郊地区是否存在对公共交通基础设施和服务（PTIS）的公平获取。设计了一项家庭问卷调查，以收集基于大阿克拉都会区（GAMA）的社会经济、社会文化、个人偏好/经历和居住地点的公共交通获取数据。获得了一个由1340名年龄在18岁至70岁之间居住在GAMA的男性和女性组成的样本。本文还使用了来自公共和开放数据库的数据。采用三步浮动集水区（3SFCA）和地理空间方法来估计空间可达性。研究发现大阿克拉都会区（GAMA）在公共交通可达性方面存在显著的高度差异。在GAMA，公共交通基础设施和服务（PTIS）的获取水平也存在显著的空间不平等。研究表明，GAMA公共交通基础设施的规划和供应使一些地区在交通服务获取方面存在不公平现象。在GAMA中发现公共交通基础设施和服务（PTIS）非常低或低的行政区，需要增加对公共交通基础设施的投资。
