Abstract
Shared mobility is discussed as one potential solution making transportation more sustainable since it can enable a more multi-modal behaviour and provides joint access to vehicle fleets. Research has focused on respective potentials for greenhouse gas (GHG) emission reductions. However, there are more external effects such as land use, accidents or noise that need to be incorporated in analyses. Thus, this work takes a systemic perspective on external cost effects regarding shifting transport demand to shared mobility services, i.e. carsharing, ridepooling, (e-)bikesharing, and shared e-scooters. To do so, survey and external cost data is combined to compute the effects of shifts to shared services concerning seven external cost dimensions. Results show that overall external costs are decreased by 2.3 % due to indicated shifts to shared services, mainly resulting from land use and GHG emission cost reductions. Yet, particularly regarding accidents, these shifts also cause external cost increases.
