Investigation involves collecting all available evidence through general surface and aerial photography; surface and aerial videography; and forensic mapping conducted using a variety of technologies, including Total Station, 3-D scanning, and aerial (drone) methods. The evidence typically collected includes, but is not limited to, scene/roadway geometry and crash related markings, stains, and gouges; vehicular damage extent and available electronic data; and witness statements/testimony, vehicular maintenance, recall and specification records, and pertinent roadway maintenance records.
