Abstract
Abstract. The pothole is called a road breakage where the surface of road is locally recessed. The conventional vehicle-mounted pothole detection sensor acquires data only when the vehicle directly contacts the pothole and moreover, the acquired data is limited to show the position information of the pothole based on the low-precision GPS. We have, therefore, studied the assessment methods for the road condition using the terrestrial LiDAR data to complement and improve the current methodology. In this study we subtract the low-resolution raster data from the high-resolution raster one that are taken from the terrestrial LiDAR, which is similar to the trend analysis. We assessed the proposed method using the manholes, which we assumed as potholes. It also showed that our method can improve a variety of perspectives such as time consuming, space extension and quantitative interpretation. As a result, we could expect the proposed method will be effectively used in the field of road management.
Highlights
The pothole is called a road breakage where the surface of road is locally recessed (Miller & Bellinger, 2003)
The study is a preliminary study to prepare for the government-initiated planning investigation
We subtracted the high-resolution data from the low-resolution data, before the road condition assessment. Data produced in this method can represent the road conditions by eliminating road slopes
Summary
The pothole is called a road breakage where the surface of road is locally recessed (Miller & Bellinger, 2003). Korea is in the same situation, a pothole is often occurred with the effect of the deicing chemicals, which prevent snow in road. These potholes having a major impact on the vehicle. We have studied the assessment methods for the road condition using the terrestrial LiDAR (Light Detection And Ranging) data to complement and improve the current methodology. Terrestrial LiDAR is a remote sensing technique that transmits a laser beam into the atmosphere and the backscattered light is detected (Kasler et al, 2010) With these advantages, LiDAR has been used in such fields as geophysics, engineerings, extraction building, Digital Surface Model (DSM) production and 3D city modelling (kreylos et al, 2008; Song et al, 2002). We assessed the proposed method using the manholes, which we assumed as potholes
