The ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems held a half-day workshop on Sustainable Urban Mobility. This was the second Workshop of this series, after a successful initial event at ACM SIGSPATIAL in 2023 in Hamburg 1. The workshop explicitly considers urban mobility as an open, complex system, and hence points to a wicked problem: estimating the global impact of any intervention to a mobility system that is aiming for less emissions, less vehicles on the road and less single-person cars, or any other sustainability goal. Often, such interventions show unintended consequences. For example, efficiency gains in one mode of mobility may show rebound effects on that mode as well as feedback loops with other modes. While we typically ignore such interrelations as "too difficult", the workshop set out to explore what the spatial computing community can contribute.
