Abstract

The C-ARS(Cooperative Automated Roadway System) refers to a road infrastructure system that links automated vehicles with road infrastructure and communicates with each other via V2X communication to support automated vehicles. The purpose of this study is to suggest a performance evaluation method of C-ARS service. This study exemplifies the 'Work zone information service' among I2V service that provide information to automated vehicles in road infrastructure. First, we define the requirements and service scope needed to check the use case analysis and service performance of the service, and propose an evaluation system for performance evaluation of these services. In addition, the evaluation system was used to verify the feasibility of evaluation through the field test of 'Work zone information service'.

자율협력주행 도로시스템은 자율주행차와 V2X 통신으로 연결되어 상호정보를 주고받으며 자율주행차의 안전주행을 지원하는 도로인프라 시스템을 말합니다. 본 연구는 자율협력주행 도로시스템 서비스의 성능평가 방안 제시를 목적으로 하며, 도로인프라에서 자율주행차에 정보를 제공하는 I2V 서비스 중 '작업구간 정보제공 서비스'를 예를 들어, 먼저 서비스에 대한 Use Case 분석과 서비스 성능을 확인하기 위해 필요한 요구사항 및 서비스 범위를 정의하고, 이러한 서비스의 성능평가 수행을 위한 평가시스템을 제안하였다. 또한, 본 연구에서 제안한 평가시스템을 활용하여 '작업구간 정보제공 서비스'의 현장시험을 통해 평가 가능여부를 검증하였다.
