We connect people across academia, public agencies, consultancies, and data and software providers to strengthen collaboration throughout the profession.
We steward the profession's knowledge by helping the community discover, preserve, and share technical expertise and practical experience.
We improve professional practice by advancing open standards, shared tools, and best practices that make travel analysis more transparent, interoperable, and reproducible.
