Alps, a versatile research infrastructure
The Swiss National Supercomputing Centre (CSCS) has a long-standing tradition of delivering top-tier high-performance computing systems, exemplified by the Piz Daint supercomputer. However, the increasing diversity of scientific needs has exposed limitations in traditional vertically integrated HPC architectures, which often lack flexibility and composability. To address these challenges, CSCS developed Alps, a next-generation HPC infrastructure designed with a transformative principle: resourc…

Effect of the Gotthard Base Tunnel:
👉 a modest but statistically significant decline in the number of cars 🚗
👉 a substantial induced rail demand effect resulting from the travel time savings 🚅
Conclusion by the authors:
on such touristic routes, road and rail transport are not perfect substitutes
My personal conclusion:
👉 Modal shift needs push & pull measures
👉 Without other measures (pricing, reduced capacity, slowing), adding capacity only increas…

The Effect of the Gotthard Base Tunnel on Road Traffic: A Synthetic Control Approach
The opening of the Gotthard Base Tunnel in 2017, the longest railway tunnel in the world, marked a milestone in Swiss transport policy. The tunnel, a part of the New Rail Link through the Alps, serves as a key instrument of the so-called "modal shift policy," which aims to transfer transalpine freight traffic from road to rail. The reduction in travel time by train between northern and southern Switzerland raised expectations that a substantial share of tourist-oriented passenger traffic would …
