Abstract

Several that analyzed the effectiveness of traffic safety facilities a method of comparing changes in the number of accidents, accident severity, speed through traffic accident data before and after installation or speed data collected from vehicle detection systems (VDS). , when traffic accident data is used, it takes a long time to collect because must be collected for at least one year before and after installation. , the road environment may change during this period, such as the addition of other traffic safety facilities in addition to the facilities to be analyzed. , the location of the VDSs for speed data is often different from the location where analysis is required, and there is a problem in that the investigators are exposed to the risk of traffic accident during on-site investigation. Therefore, this study a case study by establishing a methodology to determine effectiveness video images with a drone, extracting data using a program, and comparing vehicle driving speeds before and after speed reduction facilities. Vehicle speed surveys using drones are much safer than observational surveys conducted on highways and have the advantage of tracking speed changes along the vehicle, it is expected that they will be used for various traffic surveys in the future.

교통안전시설의 설치효과를 분석한 여러 연구사례에서는 주로 설치시점을 기준으로 전후의 교통사고자료나 지점검지기에서 수집되는 속도자료를 통해 사고건수, 사고심각도, 속도 등의 변화를 비교하는 방법을 활용하고 있다. 하지만 교통사고 자료는 설치 시점 기준 최소 전후 1년 이상 수집해야 하므로 소요시간이 길고, 자료 수집기간동안 분석 대상 시설 외에 다른 교통안전시설이 추가되는 등 도로환경이 변화하여 사고감소 효과가 분석 대상 시설로 인한 효과라고 판단하기 어려울 가능성이 있다. 또한 속도자료는 지점검지기 위치가 분석이 필요한 지점과 다른 경우가 많고 현장조사시 교통사고 위험에 노출되는 문제가 있다. 이에 본 연구에서는 드론으로 영상을 촬영하고 프로그램을 이용해 자료를 추출한 다음, 속도완화구간 도입 전과 도입 후의 차량 주행속도를 비교하여 실효성을 파악하는 일련의 방법론을 정립하여 사례연구를 수행하였다. 드론을 활용한 차량의 속도 조사는 고속도로에서 이루어지는 관측조사에 비해 훨씬 안전하게 조사할 수 있고, 차량의 주행궤적을 따라 속도 변화를 추적할 수 있는 장점이 있어 향후 다양한 교통조사에 활용될 수 있을 것으로 기대한다.
