The Transport Research Arena (TRA) is Europe’s largest and most prestigious conference on transport research and innovation, organized every two years by the European Commission and leading professional partners.

TRA brings together researchers, industry experts, policymakers, and civil society representatives to explore new solutions for the future of sustainable and smart mobility. It is where ideas meet action and where Europe’s transport community comes together to shape tomorrow’s systems and technologies.

The theme of the 2026 edition, Re-Generation in Transport, reflects a collective call for renewal in response to social, environmental, and technological challenges. It focuses on engaging the next generation of thinkers, innovators, and leaders to drive transformation toward cleaner, more efficient, and forward-looking transport systems.
