With the expertise of eight engineering & science disciplines in-house, and 55 years of forensic engineering experience, we have investigated over 20,000 collisions and incidents ranging from the simplest “fender-bender” to highly complex multi-vehicle collisions. Taking into account multiple elements, from the environmental conditions to the sequences of events, to the drivers’ behaviours, we provide an in-depth investigation and detailed analysis to support your needs. The first step for the majority of investigations is for us to produce a reconstruction of the incident. We reconstruct the sequence of events by analyzing all of the available physical evidence using the appropriate engineering and relevant scientific techniques, which may include any combination of the following: document review, research, data retrieval, vehicle & scene examinations, measurements, calculations, analysis, drawings, simulations, animations, and testing. Because no two reconstructions are exactly the same, our clients rely on our ability to use the right techniques in the right circumstances.  

Our experts are ready to tackle incidents involving any of the following:

For many investigations, you may want further analysis, and an opinion regarding driver behaviour / human factors, injury, or fraud. Once a reconstruction has been completed and we have a solid understanding of how incident occurred, we can begin tackling more complicated questions such as: Was the collision avoidable? Who was seated where? Was this injury caused by this accident? Did these vehicles even collide?  

Driver Behaviour / Human Factors

To establish liability in your case or claim, you need an expert to help answer questions such as: How fast was the driver going? Was the collision avoidable? What was the perception-response time? Did the driver respond to the hazard in a timely manner? We analyze the physical evidence and available information using the latest technology and relevant research (including our very own). Our unique peer-review process results in the most science-backed expert opinion.

Driver behaviour / human factors assessments we can conduct include:
  • Speed assessment
  • Visibility assessment
  • Hazard detection
  • Perception and response times (PRT)
  • Collision avoidance
  • Vehicle gap acceptance

Environmental & Design Factors

In the aftermath of a crash, you may need to uncover the variables that led to the incident beyond driver behaviour. What were the road and weather conditions at the time of the crash? Was weather or road design a contributing factor? Our experts can help answer these questions objectively by conducting careful engineering surveys of the scene, examining all relevant maintenance and/or design documents, and analyzing all the available physical and digital evidence using the latest technology.

Environmental / roadway design assessments we can conduct include:
  • Roadway design and geometry
  • Roadside safety
  • Contributing factors of weather
  • Determination of sun position
  • Winter maintenance
  • Traffic sign use

Fraud Investigations

When the validity of a claim is under scrutiny, you need an expert to help answer questions such as: Did these vehicles really collide? Did they collide as reported? Was it really a hit and run?  We examine the matter scientifically, and deploy our full arsenal of tools to thoroughly assess all the available physical and digital evident. An objective expert opinion may be just what you need to appropriately deal with your claim, settle your matter, or win your case.

Fraud assessments we can conduct include:
  • Vehicle electronic data downloads: EDR (or “black box”), Diagnostic Trouble Codes, Infotainment System
  • Damage consistency analysis
  • Sequence of events analysis
  • Airbag system assessment
  • Identification of driver and occupant through DNA
  • Vehicle theft / forensic locksmithing (original key, forced entry, etc.)
  • Analysis of odometer tampering and rollback
  • Vehicle fire investigations
  • Vehicle examinations

Injury Biomechanics

When injury claims arise following a motor vehicle collision, it can be tricky to separate fact from fiction. Our court-tested biomechanical assessments can help get answers to questions such as: Were impact forces great enough to cause injury? Could the injury have resulted from this incident? Was the occupant wearing a seat belt? Would a seat belt have mitigated the injury? Who was sitting where? Biomechanical assessments we can conduct include:
  • Crash severity (speed change, acceleration, forces)
  • Impact of crash severity on occupants 
  • Injury probability
  • Occupant movement (kinematics)
  • Mechanism of injury
  • Safety equipment use (i.e. seat belts, seats, child seats, and airbags)
  • Seat belt effectiveness
  • Helmet effectiveness
  • Identification of positioning of occupants (who was seated where)

Holistic Evidence Preservation Practices

We take a holistic approach to preserving vehicle and scene evidence to make sure we see the whole picture. It would be a mistake to think the black box has all the answers, when the physical damage, tire marks left at the scene, or the vehicle’s infotainment system could contain missing pieces of the puzzle that could change the outcome of an investigation. Digital data from black boxes and other electronic modules must always be considered in the context of the physical evidence. Our experts are highly trained in contextualizing all physical and digital data to ensure the view of the incident we outline for you is the scientifically accurate one. Properly collecting, preserving, and interpreting evidence is one of the most efficient and cost effective methods of finding the truth.

Peer Review Process for Bulletproof Reports

To ensure consistently high-quality forensic services, we employ a formal “Internal Peer Review” phase in all of our investigations. Internal Peer Reviewing is our quality control step whereby one professional’s opinion on a discipline or area of expertise is strengthened by that of a peer. Benefits of internal Peer Reviewing include, but are not limited to: Strengthening of the forensic opinion by the lead expert and reduction in the overall time spent on an investigation.

Research Leaders

When analyzing forensic evidence, we use only the soundest peer-reviewed technical research. But rather than relying solely on the existing knowledge base, we also fund and conduct our own research to contribute new data, models, methods, and formulae to the field. We are constantly exploring concepts that have not been studied or tested enough, or even at all. This is especially true for information that our team requires to support their analysis and reconstruction of crashes. Our Crash Test Conference is one such research initiative that allows us to remain an industry leader. Other examples relate to biomechanics, driver behaviour and pedestrian behaviour. Our company funds over 75% of its research initiatives, and our experts are authors of internationally recognized publications. Our dedication to research and education translates into a win-win-win for us, our clients, and other professionals in the industry; we continue to be trailblazers in accident reconstruction, driver behaviour and biomechanics, while our clients and peers benefit from refined expertise that stands up to the scrutiny of cross-examination.
