Combining Scene Data with Trajectory Information for Effective Accident Simulation 880066

Several accident reconstruction computer programs provide trajectory simulation information to determine the path of the vehicles from impact to rest. Many of these will even plot the information to the computer screen or printer. What all of these plotting programs seem to lack, however, is a way to include scene data such as the locations of trees, poles, and parked cars.
It is possible to merge the superior scene drawing capabilities of commercial CAD/CAM packages with the results of trajectory simulations to produce a time sequence drawing or a real time simulation. This combination of tools results in output that fully depicts the reconstruction in every detail and makes an impressive display in the courtroom should litigation be involved.
Techniques are discussed that are general to all brands of reconstruction and CAD/CAM software. Specific examples are given using CRASH3-PC, from the U.S. Department of Transportation and AutoCAD, from Autodesk, Inc.
