SAMAC Engineering - Collision/Accident Reconstruction

Collision/Accident Reconstruction

Collision reconstruction, also known as vehicle accident reconstruction, is the scientific process of investigating and analyzing how an incident occurred. Our experts have conducted thousands of investigations into all types of vehicle collisions. We provide solid answers backed by continued research into vehicle behaviour and our instrumented vehicle test facilities.

SAMAC experts use the latest technology and techniques to analyze each incident. Examples include:

  • Computer simulations and animation of vehicle motions (2D & 3D)
  • Event Data Recorders – SAMAC was among the first firms to provide clients with downloaded crash data in 2000. Using the latest Bosch software, we have continued to maintain our expertise in this area
  • Probability analyses
  • Paint analysis and matching
  • Photogrammetry – the science of obtaining measurements from photographs
  • Vehicle crash testing and data collection (in low speed collisions)
  • Microscopic lamp examinations
  • Visibility studies, including sightlines and night visibility

Our investigations have included, among others, incidents involving automobiles, motorcycles, emergency vehicles, tractor-trailer units, pedestrians and cyclists.

Types of Analyses

At SAMAC, we perform detailed analyses to assess the following:

  • Vehicle orientations and locations at impact
  • Speeds and movements of vehicles
  • Sequence of events
  • Sightlines
  • Time available for drivers to react
  • Potential to avoid incident
  • Vehicle occupant dynamics
  • Seatbelt use and effectiveness
  • Use of vehicle headlights or signals
  • Tire failure and vehicle control analyses

When investigating a vehicle collision, SAMAC personnel normally examine the vehicles involved, both externally and internally, and the location of the incident. Depending upon the particulars of the incident, the location may need to be surveyed by SAMAC personnel.

Information from police sources, photographs and witnesses are also reviewed. We routinely work with legal counsel in the preparation of questions for Examinations for Discovery to help obtain pertinent incident details.

When addressing occupant injuries, medical and occupant information will be required. As necessary, a biomechanical expert can also be requested to assist in assessing injury mechanisms, probable causation and seatbelt effectiveness.

Many investigations concern low speed/minimal damage collisions. With our extensive in-house low speed expertise and testing capability, the available information can be analyzed to determine the collision severity.
