Jyotika Athavale, Andrea Baldovin, Michael Paulitsch · 2020
The railway market is changing quickly to enable optimizations for future efficiency and environmental improvements like automated operations, infrastructure utilization, advanced analytics, system-level optimized energy-efficient driving. Additionally, consolidation at different levels (operation centers, hardware virtualization, cloud compute usage) push cost efficiency. Increased system-level connectivity pushes the needs for reliable high-speed communication. In this paper, we present the trends in modern mainline railway and possible implications on safety, differentiate from associated improvements like advanced analytics, and show how these trends can be supported from an IT technology perspective with associated safety needs. We also present elements beneficial for automated transportation.
