Real time simulation has been available since the beginning of the 90’s using accident reconstruction software. One of the most popular accident reconstruction software programs used by engineers is “PC Crash” which we have utilized for 22 years. The accident reconstruction programs will take into account the physical properties of the motor vehicle including its weight, size, center of gravity, geometry and inertial properties. In addition, the physics based model can be used to simulate the motion of the vehicle to match certain physical evidence on the roadway. That’s why it had become known as simulation software because it will simulate in virtual space, the motion of the vehicle using documented physical evidence collected or obtained from an accident scene, such as gouge marks, tire marks, final rest position, and point of impact. This information is analyzed and processed by the computer program which results in a simulation of how the vehicle got from point A to point B matching that physical evidence that was created during an accident. Matching very precise, within a couple inches. It takes many trials and errors to achieve this precision, but if you are patient, in time, you can get a very good match.
