## Summary

Cities worldwide are facing challenges with urban air quality due to emissions from transportation, particularly from internal combustion engine buses. To address this issue, many bus network operators are seeking ways to integrate battery electric buses into their fleets as a means to improve air quality. However, this integration requires careful planning and consideration of the necessary charging infrastructure to ensure operational feasibility. In response to these needs, the authors propose an integrated modeling approach that aims to determine a cost-optimal, long-term transformation plan for incorporating battery electric buses into urban bus networks. This model takes into account both strategic and operational decisions and seeks to minimize the total cost of ownership while also analyzing potential reductions in nitrogen oxide emissions. To validate their approach, the authors conducted a case study using a real-world bus network. The results demonstrate that a comprehensive integration of battery electric buses is not only feasible but also economically beneficial. Furthermore, by examining the impact of different factors such as battery capacities and charging power on the optimal fleet transformation, the authors find that medium-power charging facilities combined with medium-capacity batteries offer superior performance compared to networks with low-power or high-power charging facilities. Overall, this study highlights the importance of integrating battery electric buses into urban bus networks as a means to improve air quality. The proposed modeling approach provides valuable insights for bus network operators seeking to develop effective transformation plans that consider both economic viability and environmental impact. By adopting such plans, cities can take significant steps towards achieving sustainable and cleaner transportation systems.
