Die Entwicklung des lückenlos verschweissten Gleises (LVG) war einer der grössten Fortschritte des Gleisbaus im 20. Jahrhunderts. Das Konzept hinsichtlich der Gleislagestabilität änderte sich damit grundlegend: Unter thermischer Belastung reduzierten sich beim früheren Stosslückengleis die Längsspannungen in den Schienen, da sich diese in den verlaschten Stössen frei ausdehnen More
SRF News 10 vor 10, 22.6.2026. Die Hitze belastet die Schweizer Infrastruktur zunehmend und führt zu Schäden wie Blow-Ups auf Autobahnen und deformierten Schienen. Für Bahn und Strassenbetreiber wird der Umgang mit extremen Temperaturen zur langfristigen Herausforderung. Zum Beitrag auf srf.ch
Im Interview spricht Patrick Braess über die Herausforderungen eines zunehmend belasteten Schweizer Schienennetzes: kürzere Unterhaltsfenster, fehlende Redundanzen und die Folgen von Klimawandel und Infrastrukturalterung. Als Professor of Practice verbindet er seine Erfahrung aus der Bahnindustrie mit der Lehre und plädiert für eine stärkere Verankerung der Bahninfrastruktur in Forschung More
Major cities worldwide experience problems with the performance of their road transportation networks, and the continuous increase in traffic demand presents a substantial challenge to the optimal operation of urban road networks and the efficiency of traffic control strategies. The operation of transportation systems is widely considered to More
With urbanization and centralized economic activities, recent years have witnessed steady population growth in major cities around the globe. For example, the population in the city of Zurich has increased by 16% between 2000 and 2020, which certainly leads to an ever-growing traffic demand, potentially more traffic accidents, More

Modern cities suffer from a multitude of stressors, including congestion, pollution and crises. AntifragiCity is a new European research project that aims to deliver better services to citizens through antifragile designs, with solutions that improve under real-world stress. The Traffic Engineering group, IVT at ETH Zurich, leads the More
Cycling as a mode of transport is on an upward trend as a low-emission alternative to driving in urbanised areas nowadays. With the increasing number of cyclists, it is of great importance to assess the capacity of cycling infrastructure in practice. Simulation models are useful tools to investigate More
The average trip length in Swiss cities is under 14km, with around 60% of trips below 6km. Despite the potential for healthier, more sustainable alternatives, nearly half of the total distance travelled is by car. Bicycles play a key role in recent initiatives (e.g. E-Bike City project from More
AntifragiCity is a groundbreaking European research initiative aiming to revolutionize how urban mobility systems respond to disruptions. Rather than merely resisting shocks, AntifragiCity envisions cities that learn, adapt, and grow stronger through challenges—embracing the concept of antifragility. To realize this vision, the project will develop a comprehensive framework More

Federation of network optimisation services, simulation foresights, and data alchemy for adaptable, agile, secure, and resilient multimodal traffic management. Lack of orchestration, structured and standardized integration protocols and metadata descriptors, incorporation of real-world traffic complexities and nuances, underutilization of valuable resources, model uncertainties and integration of micro-mobility services More
Dr Hermann Patrick Braess (*1979), currently Technical Director and Head of Research and Development at TrackNet Holding Group (Tensol Rail SA and EFSA SA), as Professor of Practice in the Institute for Transport Planning and Systems (IVT), Department of Civil, Environmental and Geomatic Engineering. Hermann Patrick Braess is More
Automated vehicle technologies offer a promising avenue for enhancing traffic efficiency, safety, and energy consumption. Among these, Adaptive Cruise Control (ACC) systems stand out as a prevalent form of automation on today’s roads, with their time gap settings holding paramount importance. While decreasing the average time headway tends More
The E-Bike City project’s design is anchored in shifting away from private car use, particularly for daily commuting. It does so by ensuring access to shared vehicle hubs within 200 meters (or another designated distance) of every residence, promoting convenience and accessibility.

Eva Heinen’s interdisciplinary research looks at mobility and transportation at the intersection of sustainable development, transport planning, spatial planning, and health.
Car dependence brings along many negative social and environmental externalities that policymakers and stakeholders need to consider. Nonetheless, the concept is not well defined and lacks a clear framework regarding its determinants and mechanisms, which also leads to problems in terms of its operationalisation.
Die Verbesserungen der Verkehrsinfrastrukturen auf Strasse und Schiene können nicht wie ursprünglich geplant umgesetzt werden. Der jüngste Ausbauschritt für die Nationalstrasse wurde von der Bevölkerung abgelehnt. Die Umsetzung des Angebotskonzepts 2035 der Bahn führt zu erheblichen Mehrkosten. Das Eidgenössische Departement für Umwelt, Verkehr, Energie und Kommunikation (UVEK) hat More

Most cities do not charge for driving. Do you think that is fair? It causes externalities such as noise and pollution to residents and shops. In peak-hours of congestion, valuable life time, money, and fuel are wasted. Do you think driving in the city should be priced? Do More
The reduction of energy consumption is an increasingly important topic of the railway system. Energy-efficient train control (EETC) is one solution, which refers to mathematically computing when to accelerate, which cruising speed to hold, how long one should coast over a suitable space, and when to brake.
Inference of detailed vehicle trajectories is crucial for applications such as traffic flow modeling, energy consumption estimation, and traffic flow optimization. Static sensors can provide only aggregated information, posing challenges in reconstructing individual vehicle trajectories.
Cities allocate dedicated road space to bicycles in favor of active-mode road users. For urban environments with a mass bicycle volume, bicycle traffic congestion is likely to occur. Hence, a thorough understanding of bicycle traffic flow is necessary for the assessment of cycling infrastructure and the development of More
