With the development of cooperative driving technology, automated driving systems can share dynamic state and intention information in real-time. Accordingly, it has become possible to develop a model that comprehensively represents the influence of multiple vehicles by integrating the shared information to obtain the dynamic state information of all vehicles on the road in real time. This study developed a risk field model that can explain interactions between vehicles in real-time information of vehicles when calculating in an edge RSU in an infrastructure-centered cooperative driving environment to be used to assess the risk of a specific point of an autonomous vehicle and create a safe local route. The model showed that the range of risk influences increased as the velocity increased, the bias changed depending on the direction of acceleration, and caculating time decreases.

원전 방화지역의 화재리스크는 존모델 또는 필드모델을 사용하지만 화재 시나리오 또는 현상의 고찰 없이 사용되어온 측면이 있다. 한편 PIRT 기법은 전산코드의 적합성을 평가하고 최신기술과 입력자료의 타당성을 분석하여 우선순위 등급을 선정한다. 따라서 PIRT 기법을 화재모델링 분석에 적용할 경우 화재모델링 분석방법의 개선과 결과 값의 신뢰성을 높일 수 있는 기술로 활용할 수 있다.
