Automated Driving is expected as one of the key solutions to various social issues such as reducing traffic accidents and sustaining local transportation. This presenatation provides a brief overview of recent trends of international discussion regarding safety regulation for Automated Driving System, etc.

The realization of an advanced mobility society requires stable communication even in mobile environments. This study implemented a control xApp based on O-RAN Near-RT RIC to suppress communication interruptions during handovers on the OpenAirInterface. Furthermore, by constructing a wireless digital twin environment to replicate blockage during driving, we evaluated the impact of the proposed control method on interruption duration. This paper reports our latest results.

A Study on Reducing Operator Workload through Field-of-View Design in Remote Bus Operation Environments

Remote operation is considered as a backup when automated buses go beyond their Operational Design Domain. Since buses use many mirrors, remote operators may experience increased workload due to multi-directional monitoring. This study proposes a remote-driving environment with a display layout based on the effective visual field to reduce workload and evaluate its effectiveness using a driving simulator.

The Application of Encrypted Control Technology to CACC

Takaharu Yamada (dSPACE Japan)･kiminao Kogiso (The University of Electro-Communications)

CACC, known as the Cooperative Adaptive Cruise Control system, is a technology that maintains a constant distance between vehicles during driving by wirelessly transmitting information such as the speed and accelerator position of the preceding vehicle to the following vehicle. However, it is necessary to operate the communication channels and control parameters securely. In this study, we focused on Encrypted Control technology that enables operation with encrypted communication channels and control parameters, and attempted to apply it to CACC.

A port operation use case from the EU MODI project involving SAE Level 4 automated driving

sven Jansen･Antoine Schmeitz･Masamichi Kiyoyanagi (TNO)

One key development of the EU MODI project concerns standardisation of an interface to control automated vehicles in the logistic system. The interface is validated in a use cases executed in The Netherlands. In this use case an unmanned automated truck is sent around a port terminal for picking up/dropping off a container. Because the truck is unmanned, it also requires the interactions with the logistics systems to be automated. In this paper the use case and system architecture will be explained and results of use case demonstration in the port of Rotterdam will be shown.
