인프라 기반 자율협력주행을 위한 통신 메시지 연구 = Communication Message for Infrastructure-assisted Cooperative Automated Driving

다국어 초록 (Multilingual Abstract)

The limitations of stand-alone automated vehicles, such as limited sensor range, mixed-traffic problem, and fallback issues, require that a V2X-based cooperative automated driving system be developed. Infrastructure-supported cooperative automated driving solutions such as INFRA-Guidance are necessary to pave the way for automated vehicles to have longer sensing ranges, safe driving in mixed traffic, and minimum risk maneuvers. Message sharing and exchange based on V2X communication is essential for implementation of such services, and questions on the type of contents, From whom to whom, and what exact time to share are crucial. In such a perspective, the purpose of this study is to propose a communication message structure for INFRA-Guidance, which can be categorized into several elemental services through an analysis of the system architecture. The requirements analysis was performed to determine an appropriate structure of messages with clear and appropriate contents. The message exchange system was implemented using ASN.1 and UPER. Traffic simulation coupled with communication simulation was adopted to verify the performance of the proposed communication message structure, and we found that the proposed message is well-designed and appropriate for INFRA-Guidance.
