PC-Crash™ is a Windows™ collision & trajectory simulation tool that enables the accurate analysis of a wide variety of motor vehicle collisions and other incidents.
Step-By-Step Example of How Our Engineers Utilize PC Crash
Step 1
DJS Associates’ site measurements aligned with aerial photographic coverage of the area of the occurrence.

Step 2
Same image as step 1, but zoomed in closer to the area of the occurrence.

Step 3
A tracing of police diagram, aligned with DJS Associates’ site measurements and aerial image.
Tracing includes tire marks left by a yawing vehicle.

Step 4
Image highlighting the tire marks left by the yawing vehicle.

Step 5
Independent plot of vehicle dynamics on tire marks and manual calculation of yaw speed is performed.

Step 6
PC-Crash computer simulation is setup and input parameters are iterated.

Step 7
Iteration is performed to match the simulated vehicle dynamics with the tire marks. Vehicle yaw speed is confirmed.

Step 8
Simulation is shown in plan view on aerial photograph.

Step 9
Simulation is shown in perspective view on aerial photograph.

Step 10
Simulation is shown in perspective view on basic site drawing.
