AITools WinSMACâ„¢ is a collision prediction program that can animate an entire collision. WinSMAC predicts the pre-impact events, collision damage, and post-impact events of a two vehicle collision. The starting positions and speeds are entered for each vehicle, and WinSMAC will simulate the collision damage and trajectories. The prediction analysis can be compared to the original scene data and the reconstructed pre-impact results. If the predicted vehicle motion, rest positions and tire marks are similar to the collision scene, then you gain additional confidence in your analysis. Assumptions used in the original reconstruction can be improved and unavailable data can be estimated. See AITools WinSMAC Sample Screens.

WinSMAC is an improved Windows version of the SMAC (Simulation Model for Automobile Collisions) algorithm that was originally developed for the National Highway Transportation Safety Administration (NHTSA).

WinSMAC can incorporate pre-collision events. The vehicles can be shown moving towards impact during the approach phase, moving through the collision, and spinning out to rest. The displays are flexible and can optionally show intermediate vehicle positions, tire paths, and varying degrees of vehicle detail. The damage patterns can also be displayed.

The requirements to run ARSoftware programs are limited but important. The software requires a computer running a 32-bit version of Windows. In addition, you will need a mouse or other pointing device. The software is compact enough that there are no practical memory or storage requirements. The software can be operated in a network environment but is licensed to an individual.
