Transport is crucial for access to activities in society. Inadequate public transport (PT) result in burdensome commuting for low-income workers. Demand-Responsive Transport (DRT) promises a solution to socially inadequate PT. Drawing on experiences from a DRT Living Lab, this study examines how to organize socially sustainable PT. It focuses on possibilities and barriers identified by DRT users, employers, and PT actors. The results indicated that a DRT solution can solve social problems. However, the matter of social sustainability is charged with tensions. To integrate social considerations, there is a need to better understand the diverse conditions of PT actors.
