What is a Network Survey Vehicle?
Network Survey Vehicles (NSV) are equipped with either a thirteen Laser Profiler (13LP) or a 3D Laser Crack Measurement System (LCMS). These vehicles are designed for surveying larger local government or state road networks.
The cracks are beginning to show

As well as roughness and texture they can also report rutting. They are also fitted with a large number of calibrated digital cameras and the imagery they collect can be used for visual rating of surface defects such as cracking, or for identifying and rating roadside assets.
For very large networks an LCMS equipped vehicle can be used to automatically identify and quantify cracking using Automatic Crack Detection (ACD) software, which is faster than manual visual rating. 13LP equipped vehicles may also operate on unsealed roads, but LCMS vehicles are restricted to sealed roads.
