Contributed to the eclipse-sumo/sumo repository by developing features and documentation that improved simulation robustness, data visualization, and internationalization. Enhanced traffic simulation stability in C++ and Python by refining TLS cycle handling to safely bypass optimization when no critical flows exist, reducing errors in edge-case intersections. Advanced accessibility through Traditional Chinese localization and clarified emission reporting terminology to align with PM2.5 standards. Expanded Free-Coordinate Data output options with UTM support and improved documentation for coordinate systems and output formatting. Focused on technical writing and documentation quality, streamlining onboarding and ensuring cross-platform usability for both developers and end users.

Dec 1, 2025Month: 2025-12. This period focused on three core features for the eclipse-sumo/sumo repository that deliver business value through accessibility, clarity, and UX improvements: - Traditional Chinese localization across the Eclipse SUMO GUI, Netedit, and related UI strings, enabling broader adoption among Chinese-speaking users. Weblate-driven translations progressed through multiple commits, with GUI/Netedit at approximately 73.2% (2742 of 3745 strings) and applications at 81.3% (2266 of 2785 strings), reflecting steady localization momentum. - PM emission terminology clarification in PHEMLight documentation to align emissions reporting with PMx terminology and PM2.5 equivalence, reducing user confusion and support questions. - Enhanced visualization for TAZ relation lines, including scaling, adjustable line width, and updated usage guidance to improve interpretability and decision-making.

May 1, 2025May 2025: Focused on robustness in TLS cycle handling within eclipse-sumo/sumo. Implemented zero-critical-flow handling to gracefully skip TLS optimization when traffic is zero, emitting a warning and returning no group flows to prevent errors and unnecessary calculations. This contributed to safer, faster simulations and improved observability in edge-case intersections.
