In January 2026, Ozsoy Isik enhanced the eclipse-sumo/sumo repository by developing a user interface feature for public transport mode selection within the web wizard. Using JavaScript and Python, Ozsoy added checkboxes that allow users to select specific public transport types, directly integrating these selections into the flow generation pipeline. This approach ensured that only user-chosen modes influenced simulation outputs, reducing manual configuration and the risk of misconfiguration. The work demonstrated a solid grasp of front end and full stack development, with end-to-end integration that improved simulation fidelity and user control, though the scope was limited to a single feature.
