Expert WitnessForensic ExpertLitigation Support
Collision Analysis, Inc. was formed in 1979 to serve a recognized need for specialized consulting services in the area of automotive forensics. We have the experience and expertise to support a multi-disciplinary investigation of vehicle, biomechanical, and human factors from initial investigations to reporting and expert testimony. Our Senior Consultant, Dr. Craig Good, has a Ph.D. in mechanical engineering specializing in injury biomechanics and holds two seatbelt buckle patents.


Collision Analysis, Inc. provides the following services:

- Safety Systems Analysis
Our Company provides analysis of safety systems use, misuse, design, and performance.

• Seatbelt restraint systems in all types of vehicles
• Child restraint systems
• Seat systems
• Airbag supplemental restraint systems
• Bumper systems
• Vehicle crashworthiness
• Helmets and Helmet Testing
• Rollover protection systems
• Personal watercraft steering systems

- Injury Biomechanics Analysis
Our company provides biomechanical analyses of injuries such as those sustained by vehicle occupants, cyclists and pedestrians. We offer advanced analysis using MADYMO, a complex computer program that models human motion and response to impact. MADYMO is used by automotive manufacturers and suppliers of automotive restraint systems.

• Head and brain injury
• Spine injury
• Soft tissue injury
• Abdominal injury
• Extremities injury
• Eye injury
• Auditory system injury
• Trampoline and Foam Pit Injury

- MADYMO Modeling
MADYMO (MAthematical DYnamical MOdel) is a highly complex computer modeling program that can be used to analyze the movement and injury response of the human body to impact. Collision Analysis' experts are skilled in using this powerful tool to enhance biomechanical investigations. MADYMO's uses in forensic biomechanics include the analysis of:

• seatbelt misuse, non-use, and failure
• late airbag deployment
• frontal, side, and rear impact collisions and rollovers
• all-terrain vehicle crashes
• bicycle and pedestrian impacts

- Product Liability Investigations
Automotive product liability issues require specialized knowledge, testing, research, and analysis beyond the normal scope of general accident reconstruction. Our automotive safety systems expertise is paramount in the identification and analysis of product design, performance, and failure. Our consultants are experts at determining the presence or absence of alleged failures and proper usage or misuse by claimant.

• Three-point restraint systems
• Automatic restraint systems
• Lap belt restraint systems
• Seatbelt buckles
• Airbag restraint systems - Deployment, late deployment, non-deployment
• Child restraint systems
• Seat systems
• Braking systems
• Door latch systems
• Tire separation and failures
• Steering systems
• Suspension systems
• Vehicle stability
• Vehicle crashworthiness
• All Terrain Vehicle (ATV & UTV) design and handling characteristics
• Motorcycle and bicycle helmet protection and failures
• Personal watercraft design and handling characteristics
• After market accessories
• Misuse of product
