15. Subject 3 Safety and security analysis
Future risk level of public transport with present means of transport vs. future HSR transport
1. Determine the current transport safety level and development
2. Estimate future distributions between types of transport means
3. Estimate the future passenger safety including high-speed operations
4. Present changes in risk and consequences of the change
Uncertainty analysis is fundamental to the decision-making process => guidance on what safety factors to improve in order to increase the difference = benefits in future transportation systems
