Abstract

This study evaluates the effectiveness of a real vehicle safety performance assessment method for cooperative driving communication devices through a V2V(Vehicle to Vehicle) communication test on actual roads using two vehicles. Unlike previous studies, where experiments were conducted with fixed receiving points, this research modifies the assessment method to reflect real-world road conditions by utilizing moving vehicles for communication verification. The evaluation includes three static tests (long-distance straight road, uphill, and downhill) and three dynamic tests (short-to-long distance straight road, long-to-short distance straight road, and intersection) in various environments such as straight roads, intersections, and slopes. Additionally, the same verification was conducted in a standardized test environment (K-City). The results confirm that the standardized road-based assessment method can be effectively applied in real-road conditions. This study verifies the consistency between standardized and real-road evaluations and confirms that both environments meet the performance suitability criteria suggested in previous research, including received signal strength indicator (RSSI) and packet error rate (PER). These findings demonstrate that the assessment method reliably reflects V2X(Vehicle to everything) communication device performance in real-road conditions and can be widely applied.

본 연구는 협력주행 통신장치 장착 실차 안전 성능 평가법의 실효성을 검증하기 위해 차량 2대를 활용한 V2V(Vehicle to Vehicle) 통신 실도로 평가를 수행하였다. 기존 연구에서 수신지점이 고정된 상태에서 실험이 진행된 반면, 본 연구에서는 실제 도로 환경을 반영하기 위해 이동하는 차량 간의 통신을 기반으로 평가법을 수정하고 검증을 진행하였다. 직선로, 교차로, 경사로 환경에서 3가지 정적 평가(원거리 직선로, 경사로 상승·하강) 및 3가지 동적 평가(근거리에서 원거리 직선, 원거리에서 근거리 직선, 교차로)를 수행하였으며, 표준도로(K-City) 환경에서도 동일한 검증을 진행하였다. 실험 결과, 표준도로 기반 평가법이 실도로 조건에서도 적절하게 적용될 수 있음을 확인하였는데, 본 연구를 통해 표준도로와 실도로 간 평가 결과의 일관성을 확인하였으며, 두 환경 모두 기존 연구에서 제시한 성능 적합 기준인 수신 세기(RSSI, Received Signal Strength Indicator) 및 패킷 에러율(PER, packet Error Rate) 조건을 충족함을 확인하였다. 이를 통해 평가법이 실도로에서도 V2X(Vehicle to everything) 통신장치의 성능을 신뢰성 있게 반영할 수 있고 보편적 적용이 가능함을 확인하였다.
