Welcome messages from the leadership of APTE 2026.

Dear Colleagues and Friends,
It is my great pleasure to welcome you to the 15th Asia-Pacific Conference on Transportation and the Environment. On behalf of The Korean Society of Intelligent Transport Systems, I extend my warm greetings to all participants joining us for this important gathering.
This conference offers a valuable platform for researchers, practitioners, and students to exchange ideas, share insights, and discuss innovative solutions for building efficient, sustainable, reliable, and inclusive transport systems.
I sincerely welcome you and wish you a productive, insightful, and enjoyable experience.
Sincerely,
Prof. Dongjoo Park

Dear all,
On behalf of the Cho Chun Shik Graduate School of Mobility at KAIST, it is a great honor to host the 15th APTE in Jeju. We are delighted to bring together the Asia-Pacific mobility community to share cutting-edge research and forge new collaborations.
I hope this gathering will encourage open discussion, foster meaningful collaboration, and contribute to future mobility systems that are sustainable and inclusive.
Sincerely,
Prof. Kitae Jang

Dear participants,
We warmly welcome you to this conference, where we gather not only to reflect on transportation's profound contributions to human well-being — enhancing mobility, connectivity, and the exchange of people and goods — but also to confront its environmental and social challenges.
Today, we stand at a unique inflection point. Digital and AI technologies are unlocking extraordinary potential to transform how we promote environmentally enhancing transportation. This vision has been at the heart of the APTE Conference series since its launch in Singapore in 1998.
I am confident that every participant will benefit greatly from the insights shared here and will enjoy a rewarding and pleasant stay on Jeju Island.
Sincerely,
Prof. T. F. Fwa

Sincerely,
Dr. Inhi Kim
