Abstract

Installation of digital tachograph, black box, and ADAS have been enforced to commercial vehicles for preventing violent driving and accidents by the Traffic Safety Act in Korea. Nevertheless, the damage caused by road hazards has increased 1.5 times in 2016 compared to 2013. So, developing new technologies that can identify road hazard using the sensors installed in commercial vehicles are conducting by the Ministry of Land, Infrastructure and Transport. As a part of the technologies, this research analyze the error range of GPS installed in commercial vehicles that vary according to the driving speed. As a result, the average error was 9.72m at the driving speed of 100km/h, and the error was 2.1 times larger than the average error of 4.69m at the driving speed of 40km/h. The event point proper integration/separation range(m) was analyzed to be 20m with a recognition rate of 90% or more at the same point regardless of driving speed. The results of this research can be used as basic data for improving the accuracy of location-based data would be collected using commercial vehicles.

사업용 차량은 교통안전법상 난폭운전 및 사고 방지를 위해 운행기록계, 블랙박스, ADAS를 의무적으로 장착하여야 한다. 한편 도로 위 위험요소들로 인한 피해는 2013년 대비 2016년에 1.5배로 증가하고 있으며 이에 국토교통부는 도로위험정보를 수집할 수 있는 센서를 개발하고 사업용 차량에 장착하여 프로브 차량으로 활용할 수 있는 기술을 개발 중에 있다. 본 연구는 이러한 기술개발을 대비하여 주행속도에 따른 GPS 오차 편차 발생 여부를 확인하고 이벤트 지점을 통합·분리할 적정 통합 범위(m)를 도출하는 분석을 수행하였다. 그 결과 주행속도가 100km/h일 때 평균오차는 9.72m로 주행속도가 40km/h일 때 평균오차 4.69m에 비해 오차가 약 2.1배 커지는 것으로 나타났다. 이벤트 지점 적정 통합·분리 범위(m)는 주행속도와 관계없이 동일지점 인식률 90% 이상인 20m로 분석되었다. 본 연구결과는 사업용 차량이 수집할 위치기반 정보 정확도 향상 및 정책개발의 기초자료로 활용될 수 있을 것이다.
