Abstract

Traffic accidents in the country have steadily increased. Although IOT technologies have been applied so as to prevent the primary accident, practical solutions to prevent the secondary accident have not been suggested. A general guideline is simply recommended. In this paper, utilizing existing communication technology, we implement a proposed model and its simulation to prevent the secondary accident. When it is possible for a driver to secure visibility, the secondary accident can be prevented; In areas like tunnel, mountain terrain, and curve road with heavy traffic, where the driver has difficulty in securing the visibility, the secondary accident rates after the primary accident have been increasing. Therefore, we implement an accident prevention system that determines the primary accident utilizing sensor technology and prevents the secondary accident communicating through V2V or V2I. After the simulation, we found that the proposed model and the existing model made no difference with regard to the secondary accident rates when the visibility of the driver is secured; With the application of the proposed model, however, the accident rates decreased for 3-7 percent even though the visibility and communication were not secured.

국내의 교통사고는 지속적으로 증가하고 있다. 현재 1차 사고를 방지하기 위한 IOT 기술들이 적용되고 있지만 2차 사고방지를 위한 실질적인 대안은 제시되고 있지 않다. 단지 일반적인 지침으로 권고하고 있는 상황이다. 본 논문에서는 기존의 통신 기술을 활용하여 2차사고 방지를 위한 제안 모델 및 시뮬레이션을 구현하고 있다. 1차사고 시 운전자의 시야 확보가 가능한 상황에서는 안전거리를 확보하여 2차 사고를 예방 할 수 있지만 터널 및 산악 지형 또는 차량 통행이 많은 곡선도로와 같이 운전자의 시야확보가 어려운 지역에서는 1차사고 후 2차 사고의 확률이 점점 증가되고 있는 추세이다. 이에 본 논문에서는 1차 사고는 센서기술을 활용한 정보로 사고 판단을 하고 V2V 또는 V2I 통신을 통한 2차사고 방지를 구현하였다. 시뮬레이션을 통해 운전자의 시야가 확보되는 경우의 2차 사고는 제안 모델과 차이가 없었으나 시야가 확보되지 않고 통신이 단절된 곳에서는 제안모델이 적용된 결과 3%~7% 사고율이 감소하였다.
