Abstract

Crash scene measurement, documentation, and analysis is used to determine crash dynamics and causes in order to determine fault, liability, and prevention methods. The device to be patented is a low cost, compact system that significantly enhances the speed and accuracy of crash scene documentation, and it is applicable to aviation, highway, railway, and vessel crashes. The system will use highly accurate, kinematic, Differential Global Positioning System (DGPS) measurements to locate crash scene elements and reference points with a relative measurement error of less than two centimeters (0.79 in.). Using a government DGPS reference signal (National DGPS, US Coast Guard) or locating the reference module on a geodetic marker, allows the absolute location of the scene to be determined with an error of between three to five meters. Once the scene is measured, the device automatically develops accurate dimensions, scene drawing, and a standard report of the crash.
