Transportation Product Evaluations

Safety and performance analysis of transportation products

Exponent quantifies product performance, analyzes system and component failures, and addresses claims of manufacturing and design defects.

We help clients answer hard questions regarding the performance and safety of all types of vehicles and mobile transportation equipment.

For over five decades, Exponent has assisted manufacturers in the automotive, heavy truck, motorcycle, sports, and recreational vehicle industries in evaluating the performance of products and product components.

Our vehicle engineers determine the compliance of client products with applicable standards, regulations, and industry practice through design and safety analysis, laboratory and full-scale testing, and benchmarking analysis.

State-of-the-art Test & Engineering Center in Phoenix, AZ.

As automated driving technologies continue to advance, Exponent is uniquely positioned to define the actual performance and effectiveness of Advanced Driver Assistance Systems (ADAS) under real-world accident conditions. 

Our Test & Engineering Center (TEC) in Phoenix, Arizona is equipped with advanced robotic vehicle controllers and a full suite of AB Dynamics™ reusable robotic soft targets. We use these technologies to create complex accident scenarios, perform parametric studies of ADAS response, and rigorously address failure to equip/failure to perform allegations related to these systems.

Mechanical engine component. Exponent provides mechanical engineering research, design support, and process evaluations.

Multidisciplinary support.

Our multidisciplinary teams help clients assess allegations related to the following:

  • Mechanical and machine design
  • Safety system and component design and performance
  • Operation protection and operator field of view
  • Machine controls
  • Design and manufacturing defects
Vehicle Benchmarking Multiple

Benchmarking analysis.

Our teams regularly assist clients in determining compliance of their machines with government regulations, consensus industry standards, and industry practice through benchmarking analysis. 

Typical projects include:

  • Reconstruction of complex accidents in challenging environments
  • Component failure analysis including metallurgical and fracture surface analysis
  • Evaluation of the adequacy of maintenance and/or repair practices
  • Analysis of training practices, product documentation (operation manuals, warning, and instructional labels), and operator behavior
Vehicle Analysis Testing

Data-backed insights to quantify safety and performance.

Our vehicle engineers work with our team of data scientists to quantify the safety performance of products using statistical risk analysis methods and can rank product performance relative to peer products.

Often, claims related to the adequacy of a product design cannot be rigorously performed without a complete understanding of the circumstances of the related incident.

Detailed Reconstruction Vehicle Crash Accident

Detailed reconstructions of complex accidents.

To answer the question, "Did the alleged project deficiency or defect cause or contribute to causing the reported incident or alleged injuries?", Exponent performs detailed reconstructions of complex accidents and, if necessary, can re-create the conditions of the accident at full scale.
