Ditigalisation, new transport modes and new business models are jointly changing fast how public transport space is both produced and how travelers use it. For example, the deployment of mobile phone applications or the replacement of human presence with digital surveillance impact both workers and travelers in public transport; the latter has led to intense conflicts in Sweden lately. In this presentation we theorize and explore the evolving interface(s) between public transport workers and users by exploring three levels: 1) the sociotechnical and material elements of public transport interfaces, 2) the underlying political economic processes and rationalities that structure the interfaces, and 3) the (non)encounters between people that the interfaces give rise to. We also discuss the impacts on different groups when public transport interfaces are restructured through social, economic and technological reorganization. The research is undertaken through theoretical elaboration and a literature review to identify interfaces theoretically and empirically. Our research thus offers a novel analytical framework to contribute to deeper explorations of the relationship between economy, technology and space that together constitute what public transport is and becomes for different individuals and groups.
