초록

눈, 비, 안개, 미세먼지는 차량 운전자의 시야를 방해하고 이는 안전거리 미확보와 속도 편차의 증가를 야기하여 반복적인 대형 교통사고의 원인이 되고 있다. 본 연구에서는 안개, 눈, 비, 온도, 습도, 풍향, 풍속, 일사량, 기압, 미세먼지, 강수량 등 11종류를 측정할 수 있는 보급형 국산 도로환경센서를 개발하였으며, 기존에 상용되고 있는 안개 가시거리 센서로부터 측정된 가시거리와 개발 센서의 적외선 송·수신부를 통해 측정된 적외선 신호값을 비교하여, 두 측정값의 관계를 도출하였다. 기존 안개 가시거리 센서와 개발센서 측정값의 관계는 도로 안전에 직접적 영향을 미치는 500m 이하의 가시거리에서 측정된 데이터를 대상으로 도출되었다. 개발센서의 적외선 신호값과 기준 센서에서 도출된 가시거리의 비교 결과, 통계적으로 두 데이터 간 상관관계가 매우 높은 것으로 분석되었으며, 개발 센서의 적외선 신호값을 활용하여 안개 가시거리를 기준 센서와 매우 유의한 수준으로 추정할 수 있는 것으로 판단된다.

Snow, rain, fog, and particulate matter interfere with the vehicle driver's vision, which causes a non-secure safety distance and an increase in speed deviation, causing repetitive large-scale traffic accidents. This study developed a road environment sensor capable of measuring 11 types of fog, snow, rain, temperature, humidity, direction of wind, speed of wind, Insolation, atmospheric pressure, fine particles, rainfall, etc. and compared the visibility measured by the infrared signal value of the development sensor. The relationship between the existing fog visibility sensor and the development sensor measurement was derived from data measured at a visibility of 500m or less that directly affects road safety.
