The application of Information and Communications Technologies (ICT) to mobility has produced a wide range of smart mobility services. These services have been deployed either as large, vertically integrated solutions driven by governments or as fragmented initiatives by competing companies and consortia. Lack of open approaches has restricted the diffusion of these services. In this paper we explore two possible paths for how the value systems around smart mobility services could transition from a closed model to an open model. We use a framework and two case examples from prior research [1] to study these transitions in either centralized or decentralized path. We aim to address the potential conflicts in the evolution of smart mobility services especially from the European perspective.
