Research Report Seminar, “Research and Development of Road Technology Utilizing Various Big Data” (February 22)

[22 February, 2019]

We held a seminar, “Research and Development of Road Technology Utilizing Various Big Data”, in collaboration with Iryo Laboratory, Kobe University, Tsukai Laboratory, Hiroshima University, and Ministry of Land, Infrastructure, Transport, and Tourism (MLIT). In this briefing seminar, each project leader introduced the outline of their research on three specific projects (ETC2.0, autonomous driving, and AI for sightseeing), which are being conducted by the MILT’s Highway Bureau as part of the “New Road Technology Development Project”. Moreover, we also discussed on the future research direction and the development of road technology using various big data.



The seminar was so successful that the room was almost full. Thank you very much for your attendance. The following is a summary of the seminar.

At the beginning of the seminar, Prof. Yozo Fujino, a senior distinguished professor at Yokohama National University, gave a keynote speech on the prospects of AI and Big Data applications, mainly in the hardware field.


Prof. Iryo of Kobe University gave a presentation on the construction of a hierarchical database to improve computational efficiency when using vehicle trajectory data.


Prof. Fukuda, an associate professor of our laboratory, presented the results of research related to ETC2.0 and Wi-Fi, in which he has been mainly engaged for the past three years.


Prof. Tsukai, an associate professor of Hiroshima University, presented his research on the reconstruction of road stock effect measurement technology.


In addition, Prof. Arimura, an associate professor at Muroran Institute of Technology, and Prof. Harada, a professor at the University of Tokyo, made presentations on the road infrastructure required for the realization of an autonomous driving society.



Then, Prof. Rikiishi, an associate professor at Hiroshima University, Prof. Kuwahara at Tohoku University, and Prof. Fuse at the University of Tokyo presented their researches on the development of traffic analysis, prediction, and management methods using AI.




Finally, Mr. Mizuno of the MILT’s Road Bureau, gave a presentation on the future research direction and development of road technology utilizing various big data, and a panel discussion followed.


The following is a recap of the program of the day.
