Project Description

Wiser completed an existing conditions field survey of a 1 mile section of Mack Hatcher Parkway from Lewisburg Pike to Royal Oaks Boulevard. To meet the challenge of producing a detailed topographic survey on an extremely congested corridor without any major traffic disruptions, we captured the road surface using mobile LiDAR scanning. The scanning was completed in a few hours with no impacts on traffic flow. The data was post-processed and classified to a bare-earth surface. Striping, pavement edges, breaklines and overhead wires were extracted from the scan data using TopoDOT software which runs directly in MicroStation. The result was a much more detailed survey than would be feasible using conventional methods while avoiding any risk to field personnel or the public at a significantly lower cost to the customer.
