This paper shows a case study for a tool introduced by Elvarsson et al. (2024) identifying po tential for more efficient and effective infrastructure planning, emphasizing foresight in accom modating societal changes. The tool is used to generate and assess infrastructure developments. The assessment mirrors the societal needs of individual stakeholders showing in a transparent manner how some infrastructure developments can be favoured over others fostering consen sus-building in participatory settings. Illustrated through a case study on the Swiss A15 high way corridor, the tool is used to naively generate a large number of variants within the solution space, enabling evaluation of the variants. The study addresses uncertain land use and mobility scenarios used to assess additional highway access points in multiple futures. These variants are furthermore compared to making no change. The evaluation considers costs and benefits such as construction and maintenance cost, travel time, and environmental factors across the different scenarios, based on population growth. This scalable, open-data-reliant framework empowers regional planners to strategically allocate resources, prioritize areas, and make evi dence-based decisions, fostering transparent consensus-building. The results show that the methodology and framework can be used to streamline early-stage planning, guiding further study of specific variants, and facilitating efficient infrastructure improvements.
