SIS 77 C-ITS for Automated Driving in the Future

Session Organiser: Kevin Anegawa, TOYOTA Motor Corporation, Japan

In this session, authorities, vehicle and roadside unit manufacturers present their view on how Cooperative ITS (C-ITS) is expected to increase road safety and enhance transport automation on highways and in cities with focus on ASIL C & D (SAE L4 & 5).

Reportedly, approximately 40% of traffic accidents can be prevented by autonomous driving technology with cameras, radar, lidar and others. And furthermore, C-ITS that uses direct (short-range) communication to talk with others is contributing to reduce an additional 40% of it in Japan.

Countries around the world are making various efforts to realize Connected Automated Driving(CAD) that requires advanced applications. In Europe, studies and testing are progressing on ASIL C & D, but the use of related advanced applications requires an extended frequency spectrum.

Additionally, to realize CAD, various issues are raised: Legal systems, liability issues in the event of an accident, improvements in security technology, faster communication speeds and response to malfunctions, continued mutual compatibility of related communications, manufacturing costs including expensive parts, social acceptability and AI, etc..

Actual CAD is not so easy to realize, but we have to work on it seriously how to maximize the information availability such as what C-ITS can provide.
