효과적인 교통 통제 전략은 도시 교통 네트워크의 신뢰성을 향상시킬 것이다. 그러나, 차량 간의 조정 부족은 주로 신호되지 않은 교차로에서 빈번한 정지로 인한 혼잡을 악화시킨다. 복수의 접근 중인 커넥티드·자율주행차(요컨대 CAV)에서 기본 안전 메시지를 수집하고, 안전하고 사고 없는 차량 기동으로 효율적인 비신호 교차 운영을 보장하는 무충돌 협력 방식을 개발하는 것이 유리하다. 본 논문은 통제된 제약 조건 하에서 분산형 트래픽 조직 방법을 제안한다. 첫째, 공유 위치 기술에 의존했고 신호 불발 교차로에서 CAV의 운영 특성을 고려하여 교통 충돌을 감지 및 분석하여 CAV의 선로 설비 판단 모델을 구축했다. 선로설비 판단모델의 판단결과를 바탕으로 차량의 안전성과 운영 효율성을 더욱 보장하기 위해 교통상황별로 차량속도 안내모델을 수립한다. 실제 도시 표준 교차로를 실험 분석 대상으로 삼아 데이터 수집 및 시뮬레이션 실험을 통해 본 논문에서 제안된 신호 제어 방법과 조직 방법을 비교 분석한다. 그 결과 본 논문에서 제안된 교통조직 방식은 운영효율 46%를 향상시켜 평균 이동시간이 6.54초 줄어 신호제어 방식보다 우수할 뿐 아니라 자동차 네트워킹 기술 개발도 지원하는 것으로 나타났다.
