초록

Level 3 자율주행차의 상용화가 가시화됨에 따라 자율주행차의 운행설계영역(ODD)이 고속도로 외 도심도로로 확대될 필요가 있다. 본 연구는 도심도로 내 인프라-자율차 간 협력주행 기반의 자율주행차 서비스에 대한 교통운영효율성 및 안전성 측면의 효과평가를 통해 도심도로 자율협력주행 서비스의 실효성을 분석하였다. 도심도로 자율협력주행 서비스의 구현 및 효과평가는 미시교통시뮬레이션모델을 활용하였으며, 각 서비스별 중점관리목표에 따른 개별적인 효과평가 지표를 선정하여 효과 분석에 활용하였다. 분석 결과, V2X 통신 기반의 자율협력주행 서비스를 통해 자율주행차량의 교통운영 효율성과 안전성이 향상됨을 확인하였고, 그 효과는 자율주행차의 시장점유율이 증가할수록 커지는 것으로 분석되었다. 본 연구는 단속류인 도심도로를 대상으로 V2X 통신 기반의 자율협력주행 서비스의 효과를 도출해낸 것에 의의가 있으며, 향후 자율협력주행 서비스 검증 기반이 마련되는데 기초자료로 활용될 수 있을 것으로 기대된다.

The operational design domain (ODD) of autonomous vehicles needs to be expanded on highways and urban roads in light of the substantial commercialization of Level 3 autonomous vehicles. Therefore, this study developed a specific infrastructure autonomous vehicle-based cooperative driving service to ensure the driving safety of autonomous vehicles on city roads. The traffic operation efficiency, safety evaluation, and core evaluation indices for each service were selected and analyzed to study the effect of each service. The result of the analysis confirmed that the traffic operation efficiency and safety of autonomous vehicles were improved through the V2X communication-based autonomous cooperative driving service. On the whole, the significance of this study is in deriving the effect of the autonomous cooperative driving service based on V2X communication on urban roads with interrupting traffic flow.
