ACCIDENT RECONSTRUCTION

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:

Occupant kinematics
Vehicle kinematics
Injury aspects of biomechanics

eXHIBITS

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.

Witness marks aid in proper alignment of vehicles

Proper alignment is important to get the reconstruction right. It helps show deficiencies in the opposing case.

3D scan overlays of crushed and undeformed vehicle

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.

Occupant kinematics

Occupant Motion Relative to Vehicle

Roof interior contact aids in determining direction of forces in collision and source of injuries.

Aligning Injuries with contacted objects

Roof exterior shows head contact

Vehicle Kinematics

Starting Point - Aligned vehicles at maximum engagement

From here, you work backwards to reconstruct the collision

Next Step - Computer Simulation of car to semi-trailer

Starting Point - Aligned vehicles at maximum engagement

Computer reconstruction then matches scene evidence, vehicle evidence and physics
