The International Association of Traffic and Safety Sciences (IATSS) is a transdisciplinary platform that seeks to realize the ideal mobile society, with its core members playing leading roles in their respective fields. During its history of over 50 years, remarkable advances in transportation have brought our society both convenience and prosperity, and yet it must be acknowledged that we are still only midway along the road to safe, reliable mobility that does not burden our energy resources and the environment.

　IATSS prioritizes transdisciplinary research and studies that transcend the barriers between fields of specialization, engaging diverse stakeholders to play an active role in bringing science, policy, and society together, and build relationships of co-creation that foster mutual growth. 　IATSS is now turning its attention to mobile society in Japan and beyond, recognizing the diversity of traffic conditions and traffic cultures around the world as it develops international activities aimed at building new paradigms for mobile society in each region.

　In 2024, the IATSS celebrates its 50th anniversary and has formulated IATSS VISION 2024 to guide our future endeavors. Under the Common Vision--"We share a collective responsibility to realize a safe, sustainable, and positive mobility society where no one is left behind, both in Japan and around the world"--we aim to confront and overcome negative factors such as serious traffic accidents, environmental burdens, and health issues.

　Through our academic and collaborative activities over the next decade, we will promote a virtuous cycle in which mobility, sustainability, and well-being reinforce one another. IATSS remains committed to advancing this Common Vision through proactive and inclusive engagement.

　In closing, I would like to thank you all for your guidance and your support for our activities to date, as well as to ask for your continued support for our important work ahead.

Kazuhiko Takeuchi
President, IATSS
