dc.description.abstract
This study investigates the potential of solid-state LiDAR (SSL) technology for measuring the International Roughness Index (IRI) as an alternative to inertial profilers. Using a Livox HAP SSL sensor mounted on a vehicle alongside a reference SSI inertial profiler, measurements were conducted on a 100-meter road section exhibiting varying roughness conditions. Point cloud data from the SSL was processed to extract elevation profiles at 30-centimeter intervals, and IRI values were calculated using the quarter-car model. Comparative analysis revealed acceptable agreement between SSL and inertial profiler, with an R2 of 0.821, MAE of 1.3 (m/km), and RMSE of 1.7 (m/km). While the SSL system showed some limitations in high-roughness zones, the overall results demonstrate its potential as a cost-effective alternative for pavement condition assessment, particularly in moderate roughness conditions.
