The evidence of an accident, along with testimony and the Laws of Physics is what is called accident reconstruction. Some accidents are simple to reconstruct, and others require sophisticated programs.
Our accident reconstructions involve multi-discipline areas such as:
A picture might be worth a thousand words. It sounds trite, but so true, but what more can a video show? To comprehend a collision, seeing an airbag deployment in real time gives an indication of how fast the arbag must react.
Proper alignment is important to get the reconstruction right. It helps show deficiencies in the opposing case.
Accurate vehicle crush measurements are one of the important inputs when calculating vehicle speeds at impact. In this underride collision, 3D scans of the crushed vehicle and an exemplar undamaged vehicle allowed for precise measurement.
Roof interior contact aids in determining direction of forces in collision and source of injuries.
Roof exterior shows head contact
From here, you work backwards to reconstruct the collision
Computer reconstruction then matches scene evidence, vehicle evidence and physics
