The contemporary debate and research on transit-oriented development (TOD) has continued to progress within the context of sustainable development. At its core, this refers to providing essential transit services with an efficient manner which is achieved by including accessible public transport, mixed land use, and walkable neighbourhoods so as to reduce the volume of private cars on the road. We have analysed the theoretical development of TOD studies. Based on a scientometric analysis, this paper has collected 442 TOD articles through the Web of Science and used VOSviewer to visually map and analyse four main topics of TOD studies, including “correlation among TOD, smart growth and land use”, “TOD financing and the impacts of TOD on housing price”, “impacts of TOD on travel behaviour”, and “correlation among TOD attractiveness, accessibility and ridership”. And we also provide the current status of research and implications for Australia
