No universally accepted definition exists of the adjective “smart” as in smart city or smart mobility. Its mainstream interpretation revolves around the real-time exchange of digital data about the status of various parameters. This is expected to achieve a better “match” between the supply and demand side (e.g. of electricity, heat, mobility services etc.) in a way that triggers efficiency gains and reduces idle spare capacities. Whereas this interpretation tends to rely primarily on technical measures – without, for example, questioning the perception of mobility needs – the adjective “wise” is sometimes used to highlight the importance of a systematic reflection about the necessity of travel, trip qualities etc.
