Table 4: Research and public organizations. In terms of EU publications, almost half of the publications are journals (49%), and 21% are conference publications, showing the academic interest in the hyperloop system and the increasing research attempts in different aspects of the system. The remaining 30% is allocated to reports, which are associated mostly with private-based stakeholders. An analysis of the published literature is performed on the basis of infrastructure, pod, and performance to gain a deeper insight into the hyperloop components and performance goals that stakeholders work on. Infrastructure is divided into the (1) tube, (2) substructure, (3) interface pod-tube, (4) station, and (5) other. \"Other\" covers publications that are not covered by the four identified infrastructure areas or that refer to generic infrastructure aspects.
