# The Hyperloop System and Stakeholders: A Review and Future Directions
## 3 Analysis and Results
### Hyperloop in the EU
The pod is divided into the (1) system and propulsion, (2) interior, or (3) both. Finally, the performance of the hyperloop system is explored by considering six areas: \begin{table}

Table 5: Private companies. (1) safety, (2) energy, (3) aerodynamics, (4) traffic and capacity, (5) environment, (6) cost, and (7) other. \"Other\" refers to publications that include two or more areas or areas that are not covered within the six areas. Publications that focus on legislation were considered separately; a necessary area of research for the development of the hyperloop. Figure 6 summarizes the results of this analysis. It is noted that one publication may be attributed to one or more areas; therefore, the total sum may not be 100%. Hyperloop studies are found to conduct research related to the traction of the pod (37%) within the tube (28%) and quantify impacts related to safety (35%), energy (33%), and cost (30%). Other hyperloop areas, including passenger comfort and system acceptance, while focusing on substructure and station, are scarcer in the EU literature. For the organizations that focus on the hyperloop pod, the majority of them focus on the exterior design (i.e., related to aerodynamics), whereas only two studies were found to focus specifically on the interior. Other fields of research relate to social impacts, land implications, serviceability, and hyperloop maintenance. Different fields of research are engaged in the hyperloop system, including mechanical, transport, electric and aeronautical engineering, and business and structural experts.
