초록

V2X 환경은 C-ITS 분야에서도 최신 기술을 토대로 활발한 연구가 진행되고 있는 분야이다. 이런 최신 기술을 평가하기 위해 통신가능범위와 V2X 차량의 시장 점유율이 사용되고 있다. 본 연구는 적절한 파라미터와 V2X 차량 속도 전달 알고리즘을 적용한 미시적 교통시뮬레이션 VISSIM을 사용해 V2X 환경에서의 통신가능 범위와 V2X 차량의 시장점유율이 교통류의 흐름에 어떤 영향을 끼치는지 분석하였다. 연구 결과, V2X 환경은 차량의 교통량에 의한 혼잡을 줄여주는데 효과적인 것으로 나타났다. 하지만, 도로 용량에 근접한 혼잡상황일 시에는 V2X 환경 역시 도로 상태를 개선할 수 없었다. 또한 통신가능 범위가 길수록 효율적인 것은 아니라는 것과 낮은 시장점유율을 가지고도 V2X환경의 효과를 볼 수 있음이 밝혀졌다. 본 논문은 V2X 환경을 더 효율적으로 평가할 수 있게 만드는 하나의 기반이 될 것이다.

V2X environment is the most popular part of the C-ITS based on the high technologies. To evaluate V2X environment technologies, radio communication range and market penetration rate of V2X vehicle are used. This paper studies the V2X environment considering various traffic congestion level, radio communication range and market penetration rate of V2X vehicle using the microscopic simulation (VISSIM) based on proper parameters and algorithm. In conclusion, V2X environment can reduce the congestion in proper traffic volume. However, if traffic volume is almost near the capacity, even V2X environment can't relieve the road condition. Furthermore, increase of the radio communication range does not always mean the decrease of the congestion and even with the small market penetration rate, it can also have an impact on the V2X environment. This result will be the foundation for the V2X environment much better.
