Abstract

It is important for highway maintenance and safety assessment to get the accurate highway geometric information. However, it is difficult to acquire good highway geometric information due to missing blueprints or deteriorated highway sections. This research, to get highway geometric information rapidly, has developed a highway geometric analysis algorithm that uses data from vehicles with GPS-IMU integrated system. In conclusion, the result shows that 3.38% of error-ratio for the horizontal alignment and 0.083 absolute value difference for vertical grade comparing with highway drawings. Therefore, the result suggest that the developed method can be applied to the road safety inspection or road safety audit.

도로기하구조정보는 도로의 유지관리와 안전성 평가 등에 중요한 요소로써, 정보를 취득하려는 구간에 대한 정확한 기하구조정보를 취득하는 작업은 중요하다. 그러나, 도면이 부재하거나 선형의 결함이 발생하는 구간에서는 정확한 자료를 수집하는데 한계가 존재한다. 따라서, 이러한 구간에 도면정보를 신속하게 취득하기 위해 본 연구에서는 GPS-IMU 통합시스템이 장착된 차량에서 취득된 자료를 이용하여 도로기하구조를 측정하였다. 연구결과, 정확도의 기준이 되는 도면 값과 평면선형은 3.38%의 오차율이 나타났으며, 종단선형은 0.083의 절대값 오차가 나타났다. 따라서, 본 연구에서 도출된 결과는 도로안전점검 및 진단과 같은 도로관리업무에 활용될 목적으로 적용이 가능한 것으로 판단된다.
