Engineering Dynamics Corporation Introduces HVE-2D™

Industry Leader in Accident Reconstruction and Simulation Software Brings Windows® Version to Market

BEAVERTON, OR — December 5, 1997 — Engineering Dynamics Corporation (EDC), the world leader in the development of motor vehicle accident reconstruction and simulation software, has introduced the successor to its "industry standard" EDVAP product line. The new software program, called HVE-2D, is fully Windows-compatible. HVE stands for Human — Vehicle — Environment, the three factors that influence every accident.

HVE-2D uses a visual approach to setting up and executing reconstructions, enabling safety researchers and law enforcement personnel to perform complex accident analyses faster and more accurately. With HVE-2D it is possible to perform a preliminary EDCRASH reconstruction of the entire accident while at the scene.

To ensure accuracy and reliability, HVE-2D incorporates physics programs that have been scientifically validated using staged collisions.

EDC, based in Beaverton, Oregon, developed and marketed the first professional computer software for motor vehicle safety researchers in the early 1980's and now has over 1600 customers in 27 countries. The firm's programs were nominated for a Computerworld Smithsonian Award in the field of Transportation in 1990.
