Provided are a connected autonomous vehicle-based traffic signal system and a control method therefor. The connected autonomous vehicle-based traffic signal system allows autonomous vehicles to form a vehicle group while the autonomous vehicles and traffic lights, respectively connected thereto, communicate with each other when the autonomous vehicles enter or passes through intersections of the urban and controls the traffic lights such that the autonomous vehicles, having formed the vehicle group, can pass through the continual intersections at once without delay, thereby improving efficiency, safety, and environment friendliness in operating urban traffic signals. Moreover, the traffic signal system further improves the urban signal operating while the autonomous vehicles communicate with other adjacent autonomous vehicles and traffic lights at front intersections under an autonomous vehicle and C-ITS environment (a connected environment in which vehicle-vehicle, vehicle-roadside facilities communicate bidirectionally). The system comprises: at least one connected autonomous vehicle (100); a connected traffic light (200); and a traffic signal controller (300).
자율주행차량이 도시부 교차로에 진입 또는 통과할 경우, 각각 커넥티드되는 자율주행차량과 교통신호등이 서로 통신하면서 자율주행차량은 차량군을 형성하고, 교통신호등은 차량군을 형성한 자율주행차량이 지체 없이 연속한 교차로를 한꺼번에 통과할 수 있도록 제어됨으로써, 도시부 교통신호 운영 효율성, 안전성 및 친환경성을 향상시킬 수 있고, 또한, 자율주행차량과 C-ITS 환경(차량-차량, 차량-노변시설물이 쌍방향 통신하는 환경인 커넥티드 환경)하에서 자율주행차량이 인접한 다른 자율주행차량 및 전방 교차로의 교통신호등과 통신하면서 도시부 신호운영을 최적화할 수 있는, 커넥티드 자율주행차량-기반 교통신호 시스템 및 그 제어방법이 제공된다.
