Fast! Efficient! Safe! Accuracies of better than 1/2" for vertical clearances Accurate data on vertical clearances of roadway structures is critically important in oversize route planning. Horizontal clearance measurements must also be maintained. Traditionally collecting this data can be dangerous or can cause congestion with work crews subject to significant traffic hazards. Work must be performed during available traffic breaks which can induce errors. From a system-wide perspective clearance information in many cases is incomplete, inaccurate, difficult to maintain and difficult to access. Obtaining survey grade accuracy at traffic speeds is the proven, most efficient way to accurately measure various structures and roadway features. Deliverables:

Michael Frecks spoke on "Bridge Height Clearances Using Terrestrial Lidar in Motion" at the National Conference: Highway Asset Inventory & Data Collection Management in Durham, North Carolina. "The most exciting application we have seen out of this conference has been within the session on capturing bridge heights while keeping our surveyors safe." - Steve Varnedoe, Chief Engineer NCDOT |
