PROFILE
Gregorryb
Worked on matsim-org/matsim-libs, focusing on backend development and simulation reliability using Java. Delivered a precision-control feature by adding a command-line option to CreateScenarioCutOut, allowing users to retain original link capacities in scenario cutouts for more flexible simulation setups. Addressed data integrity by implementing a route consistency check that ensures agent plans remain valid after network cleaning, reducing the risk of routing errors. Improved simulation stability by replacing infinite link capacities with a large finite value, resolving qsim-related failures. Emphasized data validation and robust software development practices to enhance the reliability of transportation modeling and policy analysis workflows.

Feb 1, 2025February 2025 — Delivered critical stability improvements to matsim-libs, focusing on data integrity and simulation reliability. Implemented a network-cleaning data integrity check to ensure agent routes remain valid when links are removed, and replaced infinite capacities for out-of-scenario links with a large finite value to resolve qsim-related failures. These changes reduce data inconsistencies, prevent routing errors, and improve robustness of models used in planning and policy analyses.
