Bridges with low vertical clearances present a considerable risk of collision damage to oversized vehicles, with the potential to cause tragic fatalities and injuries, as well as significant vehicle and structural damage.
Maintaining an accurate and up-to-date database of vertical bridge clearances is vital to preventing potential accidents.
Traditional methods of manually surveying bridges can be time-consuming, expensive, dangerous to workers, and impede traffic flow. Clearances may also vary from lane to lane and are often difficult to obtain due to high traffic volumes.
Using mobile LiDAR, RoadViewer automatically measures vertical bridge clearances by lane without subjecting workers to a dangerous environment or negatively impacting traffic flow.
In addition to providing lane clearances and other relevant bridge details, users can examine and measure the entire bridge structure and approach in 3D LiDAR point cloud and high-resolution 360-degree imagery using the RoadViewer 3D web portal.
