Pieter Fourie is a managing director and agent-based simulation specialist with 17 years’ experience blending urban data science, transport modelling, and machine learning. He leads the MATSim Association’s open-source roadmap while holding academic appointments at Hiroshima and Keio Universities, applying MATSim to real-world testbeds for resilience and accessibility research. Pieter has a strong engineering background—contributing core algorithm and performance improvements to the widely used MATSim simulation libraries—and founded Agency Simulation Research to translate research into practice. His work bridges rigorous PhD-level research at ETH Zurich with hands-on software implementation, often focusing on feedback, emergence and path-dependence in complex transport systems. An often-overlooked strength is his experience producing analytics-ready outputs from large simulations, enabling policymakers and analysts to act on model insights.

Contributions summary:Pieter's contributions involved implementing new features within the core agent-based transport simulation library. This included the creation of a writer for ExpensiveSimScoreWriter and the development of new cost calculators and route calculations. The commits demonstrate a focus on algorithm implementation, performance optimization, and integrating new mathematical models within the established codebase. They also contributed to improvements to the transit-related parts of the simulator.
