In December 2024, Leich developed dynamic Berlin transit schedules for the matsim-scenarios/matsim-berlin repository, focusing on the S41/S42 Endless Circle Line. By replacing hardcoded timings with responsive logic and integrating updated gtfs2matsim tooling, Leich enabled the scenario to support new routes and vehicles while improving data processing robustness. The work included a targeted build and dependency cleanup, removing redundant gtfs2matsim dependencies to streamline maintenance and reduce conflicts. Using Java and Makefile, Leich also addressed data integrity by fixing link ID formatting issues, ensuring reliable data linking. The project demonstrated depth in build automation, simulation development, and transit modeling.

December 2024 — Matsim Berlin project: Focused on delivering a dynamic, data-driven Berlin transit simulation with improved tooling, while tightening build stability and data integrity. Key work centered on dynamic generation of S41/S42 schedules, integrating updated gtfs2matsim tooling, and extending the scenario with new routes/vehicles. A targeted build/dependency cleanup reduced maintenance overhead, and data integrity improvements ensured robust link-id handling. Code quality improvements aligned with project standards and tooling requirements.
