This paper explores the challenges in conducting Cost-Benefit Analysis (CBA) for urban cycling infrastructure. The authors discuss two key difficulties: determining the objective safety benefits and estimating the costs associated with implementing the infrastructure. To overcome these challenges, the authors conducted a study in Zürich, aiming to convert Mehr
Cost-benefit analysis is a tool frequently used in project appraisal to justify the implementation of infrastructures. Due to insufficient recorded data, the construction costs and safety benefits of urban bicycling infrastructure are difficult to estimate, weakening the appraisal and implementation of such projects. In this research, we conducted Mehr
Although a transition to electric vehicles (EVs) has potential to greatly reduce transportation-related greenhouse gas emissions, it faces significant challenges, including range anxiety and limitations in battery capacity. Effective long-term planning for EV charging infrastructure can overcome these barriers and increase the chances of widespread adoption.
Transportation systems are vital for economic and social development, yet are susceptible to disruptions caused by natural hazards, especially considering the adverse impacts of climate change on increasing the intensity of frequency of climatic hazards. To manage these risks effectively, stress testing, as a diagnostic tool, has shown Mehr

Das Projekt wurde vom Netzwerk Stadt und Landschaft (NSL) finanziert, um die Auswirkungen flexibler Designs bei der Bewältigung des unsicheren zukünftigen Bürobedarfs zu untersuchen. Das potenzielle Wachstum der Home-Office-Arbeitsform stellt eine große Unsicherheit für die zukünftige Büronachfrage dar. Flexible Büros können dazu beitragen, die negativen Auswirkungen dieser Ungewissheit Mehr
Infrastruktursysteme sind anfällig für Gefahrenereignisse, die ihre Funktionalität stören und direkte wie auch indirekte Folgen für die Beteiligten und die Öffentlichkeit haben. Daher müssen Infrastrukturbetreiber Eingriffe vornehmen, um die Widerstandsfähigkeit des betreffenden Systems zu verbessern. Aufgrund der Komplexität und der gegenseitigen Abhängigkeit von Infrastruktursystemen ist es von entscheidender Mehr
Die Zukunft des Schienenverkehrs wird darin liegen, dass Züge, die Passagiere und Güter transportieren, sich nahtlos von ihrem Ursprung hin zu ihrem Ziel bewegen. Potenzielle Störungen aufgrund von Zugunfällen sollen durch den umfassenden Einsatz von Überwachungstechnologien vorhergesehen und entweder durch die Umsetzung detaillierter Aktionspläne verhindert oder deren Folgen Mehr
Cities rely heavily on the services provided by water distribution networks. These networks are large and complex, consisting of thousands of kilometres of buried pipes and dozens of facilities where water is treated, pumped and stored. Infrastructure managers are entrusted with the planning and execution of interventions on Mehr
Systemweite Risiken im Transportwesen werden über alle Verkehrsträger, Regionen und kritische, voneinander abhängige Sektoren hinweg noch ungenügend verstanden, woraus sich Unwägbarkeiten hinsichtlich der Risiken aufgrund eines grösseren Systemunterbruchs ergeben. Die Verkehrsinfrastruktur ist gekennzeichnet von einem inherenten Mangel an Resilienzkonzepten, insbesondere auf lange Sicht; dies aufgrund der Unfähigkeit, Resilienzaspekte Mehr
The uncertainty on the future treatments demand, recently evidenced by the COVID-19 pandemic, makes it challenging for hospitals managers to determine the optimal design of new clinics. Flexibility can help in optimally minimizing the service risks when the benefits of the investments justify the costs, considering the dynamism of treatment Mehr
Road owners are increasingly being confronted with the need to optimize highway design for an uncertain future. A recent research project at the Infrastructure Management Chair investigated the use of a real options-based method to evaluate alternative highway designs for a fictive case study based on the A15 Mehr
This paper presents a case study based on accident reports from the Zurich City Police. Using a joint GIS and time series analysis based on negative binomial regression, the data is analyzed to identify trends in accident development for several accident subgroups (e.g., bicycle accidents, senior citizen accidents, Mehr
Parking garages are often currently designed assuming that parking demand will be stable over their lifetime. The looming mobility shift towards automated vehicles (AVs), however, makes parking demand highly uncertain, with some scenarios leading to its complete disappearance at some time in the near future. The design of Mehr
Most cities in Canada do not charge a stormwater fee; consequently, stormwater programs may need to compete with other funding priorities in public works. This often leads to a lack of dedicated and predictable cash flow, which can limit municipalities‘ capacity to sustain stormwater services.
The potential large-scale transition from working in the office to working at home, is a massive uncertainty related to the future needs of office space in our cities. It is in the face of this uncertainty, that real estate developers must manage their portfolios. The use of the Mehr
