On November 24, the Federal Expansion Step 2023 for Road was put up for a public vote. The Expansion Step 2023 is a project programme for national roads consisting of six major projects, including the widening of the A1 highway between Bern and Nyon, as well as three More
The transport infrastructure planning process in Canton Zürich. With examples of planning infrastructure in Dübendorf-Hinwil corridor
Responsiveness of Transport Infrastructure Planning Processes
Responsiveness of planning processes is the ability to meet changing societal transport needs quickly in ways that are acceptable to all stakeholders. In Switzerland, considerable traffic jams and overfilled trains indicate that planning processes could be made more responsive. As delays for travelers persist, their needs are not More
Overcoming challenges in cost-benefit analysis of urban cycling infrastructure
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 More
Cost Benefit Analysis of Cycling Infrastructure
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 More
Adaptive Planning for Electric Vehicle Charging Infrastructure
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.
Stress Testing Transport Systems
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 More
Adaptive Urban Planning for an Uncertain Future: Infrastructure Interventions for the Technological Shift in Transportation
Planning cities to adapt to the future is challenging due to complex interactions between mobility, infrastructure, and land use. This challenge is exacerbated by the need to study future uncertainties such as ever-shifting demographics and industrial landscape, increased environmental and climatic changes, disruptive and unpredictable technological development, and More

Investing in Water Supply Resilience Considering Future Uncertainty and Management Flexibility
The infrastructure required to provide sufficient high quality drinking water to urban areas over long time horizons is highly uncertain. The use of the real options method, which accounts for future uncertainty and considers management flexibility over time, can significantly improve the evaluation of water supply resilience enhancing More
Future-proof urban development. Evaluating the impact of flexible assets in coping with the uncertain future conditions
The project was funded by the Network City and Landscape (NSL) to investigate the impact of flexible designs in coping with the uncertain future offices demand. The potential growth in the home-office working mode poses a large uncertainty on the future offices demand. Flexible offices can help limiting More
Multi-Stakeholder Decision support framework to identify and evaluate resilience improvement interventions for interdependent infrastructure systems
Infrastructure systems are susceptible to hazard events, which disrupts their functionality leading to direct and indirect consequences for their stakeholders as well as the public. Therefore, infrastructure managers need to execute interventions to improve the resilience of their system of interest. Due to the complexity and interdependency of More
Maintaining train schedule STABILITY and managing time table reserves via digitalized railway intervention planning
The future of rail transport will be one where trains carrying passengers and goods flow seamlessly from their origins to their destinations. Potential disruptions due to train incidents will be foreseen with the extensive use of surveillance technologies, and either prevented through the implementation of detailed action plans More
Exploiting Digitalisation to Plan Interventions on Large Water Distribution Networks
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 More
Future-proofing strategies FOr RESilient transport networks against Extreme Events (FORESEE)
System-wide transportation risks are not well understood across modes, regions, and critical interdependent sectors, creating uncertainty about risks resulting from a major system disruption. There is a lack of resilience schemes, especially for the long term, integrated into transport infrastructure due to an inability to monetize resilience for More
Evaluating Initial Building Designs Considering Possible Future Changes and Decision Flexibility: The Example of The New PET Centre of the University Hospital of Zurich
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 More
Quantitative Evaluation of Highway Designs Considering Uncertainties in Future Mobility Patterns and Flexibility Using Real Options
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 More
Identifying Changes in Bicycle Accident Trends Using GIS and Time Series Information in the City of Zürich
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, More
Considering Automated Vehicle Deployment Uncertainty in the Design of Optimal Parking Garages Using Real Options
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 More
Sustainable Funding Strategies for Stormwater Infrastructure Management: A System Dynamics Model
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.
Flexible Office Space for the Age of Distributed Work
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 More
