Utilization of Mobile LiDAR to Verify Bridge Clearance Height on the Western Kentucky Parkway

Bridge clearances can vary from lane-to-lane beneath overpasses, and can often be difficult to measure due to high traffic volumes. Therefore, a mobile LiDAR unit was utilized in this project to obtain the bridge clearance heights on the Western Kentucky Parkway. The LiDAR information was collected at 400,000 points-per-second at a driving speed of 30 mph. Hand measurements were also taken on each bridge to assist in quantifying the potential error between field measurements and LiDAR measurements. The results of the collected LiDAR data appear to be less than 1.2 inches, which appears to be in line with both manufacturer and industry standards.
